1 00:00:03,040 --> 00:00:06,800 Speaker 1: Welcome to Stuff to Blow Your Mind production of iHeartRadio. 2 00:00:13,240 --> 00:00:15,600 Speaker 2: Hey, welcome to Stuff to Blow Your Mind. My name 3 00:00:15,640 --> 00:00:16,639 Speaker 2: is Robert Lamb. 4 00:00:16,840 --> 00:00:19,200 Speaker 3: And I'm Joe McCormick, and we're back with part two 5 00:00:19,320 --> 00:00:22,520 Speaker 3: of our series on the horse hoof. Now. In part one, 6 00:00:23,040 --> 00:00:26,400 Speaker 3: we discussed the anatomical form of the horse hoof, with 7 00:00:26,440 --> 00:00:30,160 Speaker 3: an emphasis on the alarming fact that the hoof is 8 00:00:30,280 --> 00:00:35,519 Speaker 3: essentially a highly specialized form of the tetrapod middle finger. 9 00:00:35,680 --> 00:00:37,960 Speaker 3: So when you see a horse galloping around, yes, it 10 00:00:38,080 --> 00:00:42,600 Speaker 3: is running around on all middle fingers and toes. We 11 00:00:42,680 --> 00:00:45,959 Speaker 3: talked about an ancient legend about the horse ridden by 12 00:00:46,040 --> 00:00:50,360 Speaker 3: Julius Caesar, which some artists have depicted as having dock 13 00:00:50,479 --> 00:00:53,520 Speaker 3: and hair and human feet instead of hoofs, at least 14 00:00:53,520 --> 00:00:57,560 Speaker 3: on the first two legs. Rob's idea, I think was 15 00:00:57,640 --> 00:01:00,280 Speaker 3: that this it's possible that these stories could be based 16 00:01:00,320 --> 00:01:04,759 Speaker 3: on observations of what are called polydactyl horses, horses born 17 00:01:04,840 --> 00:01:08,120 Speaker 3: with extra hooflets on the sides of the primary hoof, 18 00:01:08,160 --> 00:01:09,440 Speaker 3: which do in fact exist. 19 00:01:09,840 --> 00:01:13,640 Speaker 2: Yeah, this seems to be the more sensible interpretation that 20 00:01:13,680 --> 00:01:17,000 Speaker 2: you see taken by folks, and I don't think anyone's 21 00:01:17,040 --> 00:01:22,360 Speaker 2: actually arguing that these horses had like human fore feet, 22 00:01:23,160 --> 00:01:27,080 Speaker 2: but it looks hilarious in the illustrations. It does. 23 00:01:27,160 --> 00:01:30,440 Speaker 3: And we finally talked about the evolution of the horse hoof, 24 00:01:30,520 --> 00:01:34,199 Speaker 3: with the commonly accepted narrative being that millions of years ago, 25 00:01:34,440 --> 00:01:38,959 Speaker 3: the ancestors of modern horses lived in more forested environments, 26 00:01:39,000 --> 00:01:42,759 Speaker 3: maybe warmer, wetter environments. They were much smaller, maybe about 27 00:01:42,760 --> 00:01:46,800 Speaker 3: the size of dogs, and had multiple toes per feet. Then, 28 00:01:47,040 --> 00:01:51,680 Speaker 3: due to climate and habitat changes, they became grassland dwellers, 29 00:01:51,720 --> 00:01:56,320 Speaker 3: which drove them to evolve larger body sizes and select 30 00:01:56,360 --> 00:01:59,960 Speaker 3: for galloping speed. And these changes coincided with the law 31 00:02:00,400 --> 00:02:03,520 Speaker 3: of peripheral toes until you end up with the modern 32 00:02:03,560 --> 00:02:06,400 Speaker 3: horse and its relatives in the genus equis, so that 33 00:02:06,400 --> 00:02:09,919 Speaker 3: would include the zebra and the ass, all having only 34 00:02:10,040 --> 00:02:14,080 Speaker 3: one toe per foot, the columnar hoof. Now today, we 35 00:02:14,120 --> 00:02:16,560 Speaker 3: wanted to continue the series on the horse hoof, getting 36 00:02:16,560 --> 00:02:20,359 Speaker 3: into a couple other things about horsecof evolution as well 37 00:02:20,360 --> 00:02:23,720 Speaker 3: as the invention of the horseshoe. But before we do that, 38 00:02:24,000 --> 00:02:27,440 Speaker 3: I wanted to take a brief detour into a metaphorical 39 00:02:27,480 --> 00:02:32,760 Speaker 3: connection to the hoof, which concerns medical diagnostics, and more generally, 40 00:02:32,800 --> 00:02:38,279 Speaker 3: the realm of statistical reasoning. So there's a famous aphorism 41 00:02:38,720 --> 00:02:43,000 Speaker 3: widely used in medical education, often invoked by practicing physicians, 42 00:02:43,360 --> 00:02:46,480 Speaker 3: and it goes like this, when you hear hoof beats, 43 00:02:46,639 --> 00:02:51,200 Speaker 3: look for horses, not zebras. Rob. I think this saying 44 00:02:51,280 --> 00:02:53,280 Speaker 3: may have come up on the show in the past, 45 00:02:53,320 --> 00:02:56,040 Speaker 3: though I couldn't remember when, but I'm sure you've heard 46 00:02:56,040 --> 00:02:58,000 Speaker 3: this before, right, Yeah. 47 00:02:58,160 --> 00:03:02,120 Speaker 2: Yeah, basically is what it sounds like, right, it's, you know, 48 00:03:02,200 --> 00:03:05,640 Speaker 2: whatever the evidence seems to indicate, go for the more 49 00:03:05,800 --> 00:03:12,239 Speaker 2: likely and more statistically reasonable explanation for the evidence. Right. 50 00:03:12,400 --> 00:03:14,240 Speaker 3: So I was looking up the history of this quote 51 00:03:14,240 --> 00:03:17,480 Speaker 3: in a chapter on medical aphorisms in a book called 52 00:03:17,560 --> 00:03:22,280 Speaker 3: White Coat Tails Medicine's Heroes, Heritage and Misadventures by Robert B. 53 00:03:22,480 --> 00:03:26,080 Speaker 3: Taylor published by Springer. So I'll refer back to that 54 00:03:26,160 --> 00:03:28,200 Speaker 3: chapter in a second. But yeah, Rob, like you said, 55 00:03:28,240 --> 00:03:31,160 Speaker 3: the point of this aphorism is that when a patient 56 00:03:31,240 --> 00:03:35,000 Speaker 3: presents with symptoms X, Y, and Z, you should start 57 00:03:35,160 --> 00:03:39,440 Speaker 3: by thinking about the most common conditions within the population 58 00:03:40,000 --> 00:03:43,800 Speaker 3: associated with that cluster of symptoms, rather than jumping to 59 00:03:43,880 --> 00:03:47,800 Speaker 3: assumptions about rare diseases. So, for example, if a patient 60 00:03:47,880 --> 00:03:51,760 Speaker 3: presents at a US clinic with flu like symptoms, it's 61 00:03:51,800 --> 00:03:54,840 Speaker 3: better to start by investigating the possibility that they have 62 00:03:55,040 --> 00:03:59,520 Speaker 3: the flu or common cold, or now maybe COVID, rather 63 00:03:59,560 --> 00:04:02,920 Speaker 3: than to by investigating whether they have contracted the hindra 64 00:04:03,120 --> 00:04:07,560 Speaker 3: virus from a flying fox in Australia. Taylor traces this 65 00:04:07,720 --> 00:04:11,440 Speaker 3: saying back to an American medical researcher named Theodore E. 66 00:04:11,640 --> 00:04:14,560 Speaker 3: Woodward who lived nineteen fourteen to two thousand and five, 67 00:04:15,080 --> 00:04:18,720 Speaker 3: who taught at the University of Maryland School of Medicine. 68 00:04:18,920 --> 00:04:21,480 Speaker 3: And it seems actually the common form of this aphorism 69 00:04:21,560 --> 00:04:25,839 Speaker 3: might be a paraphrase, and the more accurate original quote 70 00:04:26,680 --> 00:04:30,960 Speaker 3: may have been don't look for zebras on Green Street. 71 00:04:31,720 --> 00:04:34,160 Speaker 3: That might be a little perplexing, but it makes sense 72 00:04:34,160 --> 00:04:37,800 Speaker 3: in the context because Green Street was the location of 73 00:04:37,920 --> 00:04:41,039 Speaker 3: the University of Maryland hospital in Baltimore, and he was 74 00:04:41,080 --> 00:04:44,159 Speaker 3: teaching at the University of Maryland two students there, So 75 00:04:44,240 --> 00:04:45,800 Speaker 3: of course you can see why it would need to 76 00:04:45,839 --> 00:04:49,120 Speaker 3: be rephrased to make more sense outside of its original locality. 77 00:04:49,200 --> 00:04:54,680 Speaker 3: But I also think the localization to Baltimore geography highlights 78 00:04:54,839 --> 00:04:58,440 Speaker 3: something important, which is that this aphorism is only useful 79 00:04:58,480 --> 00:05:02,560 Speaker 3: when you're talking about a no own population of patients 80 00:05:02,560 --> 00:05:06,120 Speaker 3: in which the frequency of certain diseases or conditions is 81 00:05:06,240 --> 00:05:09,200 Speaker 3: fairly well understood. Because if you were talking to a 82 00:05:09,200 --> 00:05:12,360 Speaker 3: group of medical students, maybe in a region of southern 83 00:05:12,400 --> 00:05:15,680 Speaker 3: Africa where zebras are abundant, it might make sense to 84 00:05:15,760 --> 00:05:18,760 Speaker 3: use the aphorism inverted, I guess, depending on how many 85 00:05:18,760 --> 00:05:21,479 Speaker 3: horses there are around as well. But in the same sense, 86 00:05:21,560 --> 00:05:23,880 Speaker 3: you have to know what the frequencies are in the 87 00:05:23,920 --> 00:05:26,480 Speaker 3: population you're looking at before deploying this. 88 00:05:27,640 --> 00:05:28,560 Speaker 2: Yeah, that's true. 89 00:05:28,920 --> 00:05:32,080 Speaker 3: Now, I find this the reasoning behind the saying actually 90 00:05:32,160 --> 00:05:34,240 Speaker 3: kind of interesting, because if you interpret it in the 91 00:05:34,360 --> 00:05:37,120 Speaker 3: usual way, it's a piece of advice that can seem 92 00:05:37,200 --> 00:05:41,720 Speaker 3: rather obvious, like common explanations are more common than rare ones. 93 00:05:42,440 --> 00:05:46,200 Speaker 3: But I think as a general rule, when looking for explanations, 94 00:05:46,680 --> 00:05:50,120 Speaker 3: we do have to be reminded to start by considering 95 00:05:50,520 --> 00:05:55,000 Speaker 3: what is most likely in terms of frequency, because there 96 00:05:55,000 --> 00:05:59,040 Speaker 3: are all kinds of mental biases that constantly tempt us 97 00:05:59,440 --> 00:06:04,320 Speaker 3: to start looking for highly unusual causes for unexplained phenomena 98 00:06:04,720 --> 00:06:09,640 Speaker 3: before we've exhausted all of the extremely commonplace candidates for 99 00:06:09,720 --> 00:06:15,080 Speaker 3: one thing. Unusual causes and explanations are usually more exciting. 100 00:06:15,480 --> 00:06:17,840 Speaker 3: They kind of stick in the mind because of our 101 00:06:17,960 --> 00:06:21,240 Speaker 3: level of interest in them, and they can quite easily 102 00:06:21,320 --> 00:06:24,279 Speaker 3: then come to mind when we start searching around for 103 00:06:24,360 --> 00:06:26,960 Speaker 3: an explanation. They're sort of at the top of the 104 00:06:27,000 --> 00:06:30,800 Speaker 3: toy box right now. In this section of the book 105 00:06:30,839 --> 00:06:34,159 Speaker 3: I was talking about, Taylor makes an interesting point about 106 00:06:34,200 --> 00:06:38,200 Speaker 3: the zebra aphorism, which I hadn't quite considered. I was 107 00:06:38,240 --> 00:06:41,240 Speaker 3: just thinking at the first order level of more common 108 00:06:41,279 --> 00:06:45,400 Speaker 3: explanations and less common explanations. But Taylor also writes quote 109 00:06:45,480 --> 00:06:51,400 Speaker 3: as a clinical corollary, experienced diagnosticians look first for uncommon 110 00:06:51,560 --> 00:06:59,200 Speaker 3: manifestations of common conditions rather than common manifestations of uncommon diseases. 111 00:07:00,160 --> 00:07:03,479 Speaker 3: Now that seemed really interesting to me. I hadn't quite 112 00:07:03,480 --> 00:07:05,520 Speaker 3: thought about it that way. And of course it would 113 00:07:05,520 --> 00:07:08,640 Speaker 3: depend on exactly how uncommon you mean in each clause 114 00:07:08,680 --> 00:07:11,160 Speaker 3: of that sentence, Like if you were to represent them 115 00:07:11,160 --> 00:07:14,560 Speaker 3: as actual percentage chances and stuff, the math might break 116 00:07:14,600 --> 00:07:16,920 Speaker 3: out in different ways. But if a certain set of 117 00:07:17,000 --> 00:07:20,120 Speaker 3: symptoms appears in I don't know, only three percent of 118 00:07:20,240 --> 00:07:23,960 Speaker 3: cases of an extremely common condition that affects you, know, 119 00:07:24,080 --> 00:07:27,600 Speaker 3: millions of people every year. It is probably still worth 120 00:07:27,640 --> 00:07:32,880 Speaker 3: investigating that diagnosis, the uncommon manifestation of the extremely common 121 00:07:32,960 --> 00:07:36,600 Speaker 3: condition before you look at the possibility of a condition 122 00:07:36,680 --> 00:07:40,400 Speaker 3: that matches the symptoms very closely. But you know, you 123 00:07:40,480 --> 00:07:42,560 Speaker 3: might only see only a couple of cases in the 124 00:07:42,560 --> 00:07:46,760 Speaker 3: world per year, it's extremely rare. You'd still get way 125 00:07:46,880 --> 00:07:51,360 Speaker 3: more hits of confirmation on the on the uncommon version 126 00:07:51,560 --> 00:07:52,640 Speaker 3: of the common condition. 127 00:07:53,040 --> 00:07:55,880 Speaker 2: It reminds me of various discussions we've had about cryptozoology 128 00:07:56,360 --> 00:08:02,040 Speaker 2: and the interpretations and misinterpretations of dead animals and in 129 00:08:02,080 --> 00:08:06,840 Speaker 2: some cases dead human beings, where you're looking at some 130 00:08:07,000 --> 00:08:09,520 Speaker 2: rate of decay and yeah, are you looking at it 131 00:08:09,560 --> 00:08:13,080 Speaker 2: as an uncommon manifestation of a common condition? In other words, 132 00:08:13,120 --> 00:08:15,040 Speaker 2: are you looking at is kind of like a novel 133 00:08:15,720 --> 00:08:21,160 Speaker 2: pattern or appearance in decay of just a normal, mundane animal, 134 00:08:21,680 --> 00:08:24,720 Speaker 2: or are you going to jump to that extreme level 135 00:08:24,720 --> 00:08:27,240 Speaker 2: and think, well, no, this is just how it looks 136 00:08:27,560 --> 00:08:30,480 Speaker 2: and we've just never seen this creature before. Yeah. 137 00:08:30,600 --> 00:08:33,400 Speaker 3: Yeah. However, I want to come back on the other end, 138 00:08:33,600 --> 00:08:38,040 Speaker 3: because if you search for medical case reports citing this aphorism, 139 00:08:38,120 --> 00:08:40,560 Speaker 3: which I was doing a lot of times, it will 140 00:08:40,600 --> 00:08:45,400 Speaker 3: be specifically to discuss cases where it was a zebra 141 00:08:45,520 --> 00:08:49,840 Speaker 3: on Green Street, the rare and unexpected diagnosis that turned 142 00:08:49,880 --> 00:08:52,880 Speaker 3: out to be correct. So just one example I was 143 00:08:52,920 --> 00:08:56,800 Speaker 3: looking at this was a case report published in Clinical 144 00:08:56,840 --> 00:09:00,680 Speaker 3: Practice in Cases in Emergency Medicine in twenty nineteen by 145 00:09:00,760 --> 00:09:03,960 Speaker 3: Loupez at All called Beware of the Zebra nine year 146 00:09:03,960 --> 00:09:07,400 Speaker 3: old with Fever. I believe this incident took place in 147 00:09:07,440 --> 00:09:09,719 Speaker 3: the US state of North Carolina. So it was a 148 00:09:10,080 --> 00:09:13,640 Speaker 3: nine year old girl whose family spoke only French, and 149 00:09:13,720 --> 00:09:18,720 Speaker 3: they presented at the hospital with the patient having an 150 00:09:18,880 --> 00:09:23,760 Speaker 3: abdominal pain, vomiting, intermittent fevers, fatigue, and headache, and because 151 00:09:23,760 --> 00:09:26,199 Speaker 3: there was a language barrier, everything had to be done 152 00:09:26,200 --> 00:09:28,320 Speaker 3: with the help of an interpreter, and it seems that 153 00:09:28,400 --> 00:09:32,480 Speaker 3: this led to some maybe some original misunderstandings about the 154 00:09:32,520 --> 00:09:36,000 Speaker 3: case history. So the doctors tried to diagnose based on 155 00:09:36,080 --> 00:09:39,360 Speaker 3: all the normal explanations that they would be likely to 156 00:09:39,400 --> 00:09:42,679 Speaker 3: see in their patient population, but none of the common 157 00:09:42,720 --> 00:09:47,000 Speaker 3: diagnoses really fit her case. Her condition continued to get worse, 158 00:09:47,040 --> 00:09:50,120 Speaker 3: it even became life threatening, and the breakthrough seemed to 159 00:09:50,120 --> 00:09:53,199 Speaker 3: come when the doctors began looking outside the normal slate 160 00:09:53,240 --> 00:09:56,760 Speaker 3: of conditions encountered in their practice in the United States. Finally, 161 00:09:57,200 --> 00:09:59,839 Speaker 3: they learned that the girl's family had just in the 162 00:09:59,840 --> 00:10:04,440 Speaker 3: wa weeks before, arrived from the Congo, where malaria is common. 163 00:10:04,840 --> 00:10:08,160 Speaker 3: The care providers eventually ordered a test that would put 164 00:10:08,160 --> 00:10:11,319 Speaker 3: them on the right track. They write in their report, quote, 165 00:10:11,480 --> 00:10:15,080 Speaker 3: this test was a peripheral blood smear, specifically a thick 166 00:10:15,120 --> 00:10:19,440 Speaker 3: and thin smear, which revealed Plasmodium falciparum. And this is 167 00:10:19,440 --> 00:10:23,480 Speaker 3: one of the protozoa responsible for causing malaria, leading to 168 00:10:23,520 --> 00:10:27,120 Speaker 3: a final diagnosis of cerebral malaria. And then they write 169 00:10:27,280 --> 00:10:30,239 Speaker 3: from here they contacted the twenty four hour CDC hotline 170 00:10:30,320 --> 00:10:36,040 Speaker 3: to immediately get the appropriate anti malarial medication. They put 171 00:10:36,040 --> 00:10:38,920 Speaker 3: the girl on a quinine drip and admitted her to 172 00:10:39,040 --> 00:10:42,880 Speaker 3: the pediatric intensive care unit. And then they say, quote remarkably, 173 00:10:42,920 --> 00:10:45,440 Speaker 3: within four weeks she made a full recovery and returned 174 00:10:45,480 --> 00:10:49,000 Speaker 3: home with her family. So thankfully, the patient was all 175 00:10:49,080 --> 00:10:52,000 Speaker 3: right in the end, but she potentially could have died 176 00:10:52,040 --> 00:10:56,679 Speaker 3: if doctors hadn't made the locally unusual but correct diagnosis 177 00:10:56,720 --> 00:10:59,440 Speaker 3: and given her the right treatment. And so the authors 178 00:10:59,440 --> 00:11:02,319 Speaker 3: say in their conclusion quote, many of us are taught 179 00:11:02,360 --> 00:11:05,600 Speaker 3: the common aphorism in medical school. When you hear hoof beats, 180 00:11:05,679 --> 00:11:09,000 Speaker 3: think horses, not zebras. When approaching a nine year old 181 00:11:09,000 --> 00:11:11,640 Speaker 3: with fever, we hear the hoof beat symptoms and tend 182 00:11:11,640 --> 00:11:14,760 Speaker 3: to think of the typical diagnoses that are commonly seen 183 00:11:14,880 --> 00:11:18,160 Speaker 3: in our pediatric population. Yet if we are not thinking 184 00:11:18,240 --> 00:11:21,520 Speaker 3: about the zebras, we will miss this common presentation of 185 00:11:21,559 --> 00:11:24,560 Speaker 3: a disease that is uncommon north of the equator, which 186 00:11:24,559 --> 00:11:28,200 Speaker 3: could lead to high morbidity and possibly even mortality for patients. 187 00:11:28,960 --> 00:11:31,280 Speaker 3: So it's very good that they were able to discover 188 00:11:31,360 --> 00:11:35,560 Speaker 3: this intervene and probably save the girl's life. But it 189 00:11:35,640 --> 00:11:39,160 Speaker 3: highlights how there's a difficult balance, Like if you go 190 00:11:39,360 --> 00:11:43,120 Speaker 3: looking for zebras before you look for horses on Green Street, 191 00:11:43,320 --> 00:11:45,800 Speaker 3: you will waste a lot of time and resources and 192 00:11:45,840 --> 00:11:50,240 Speaker 3: potentially cause frequent misdiagnoses that could harm people. But if 193 00:11:50,240 --> 00:11:53,959 Speaker 3: you never consider the possibility of zebras on Green Street, 194 00:11:54,040 --> 00:11:56,880 Speaker 3: there will be rare but very real cases where you 195 00:11:56,920 --> 00:11:59,040 Speaker 3: could save somebody's life but you don't. 196 00:12:00,080 --> 00:12:02,760 Speaker 2: So that's a great point. Yeah, certainly looking at the 197 00:12:02,880 --> 00:12:06,360 Speaker 2: like the professional end of the scenario, because on the 198 00:12:06,360 --> 00:12:08,839 Speaker 2: other end, like say the user end and the media end. 199 00:12:09,320 --> 00:12:12,680 Speaker 2: I mean, zebra on Green Street. That's a great headline. 200 00:12:13,160 --> 00:12:15,640 Speaker 2: You're gonna that's this headline that's gonna stick in your mind, 201 00:12:16,000 --> 00:12:17,800 Speaker 2: and then when you're going to see the doctor, you're 202 00:12:17,840 --> 00:12:20,720 Speaker 2: gonna be like, hey, doc, is it possible that a 203 00:12:20,800 --> 00:12:23,760 Speaker 2: rare amiba is eating my flesh? Or something to that effect, 204 00:12:23,840 --> 00:12:26,320 Speaker 2: because that's what you saw in the headline, that's what 205 00:12:26,360 --> 00:12:31,600 Speaker 2: you saw on the the documentary series that that that 206 00:12:32,200 --> 00:12:34,880 Speaker 2: sensationalized a rare case, right. 207 00:12:34,920 --> 00:12:38,120 Speaker 3: I mean, the the difficult thing is like, because of 208 00:12:38,160 --> 00:12:41,920 Speaker 3: the way we emotionally react to stories like this, I 209 00:12:41,920 --> 00:12:44,319 Speaker 3: feel like it kind of tends to have the effect 210 00:12:44,320 --> 00:12:46,320 Speaker 3: of making us think, well, maybe then I should start 211 00:12:46,360 --> 00:12:51,679 Speaker 3: looking for diagnoses of unusual diseases in patient populations. So 212 00:12:51,840 --> 00:12:55,520 Speaker 3: it just highlights like diagnosis in the specific case of medicine, 213 00:12:55,600 --> 00:13:02,240 Speaker 3: and searching for explanations for unknown phenomena generally is really difficult. 214 00:13:02,320 --> 00:13:08,080 Speaker 3: It involves a balance between prioritizing likely explanations, which are 215 00:13:08,280 --> 00:13:12,000 Speaker 3: you know, by very definition, almost always going to be correct, 216 00:13:12,280 --> 00:13:16,080 Speaker 3: but also being open minded enough to catch the unusual 217 00:13:16,320 --> 00:13:20,040 Speaker 3: ones when they arise. And obviously, I think a big 218 00:13:20,040 --> 00:13:23,320 Speaker 3: part of the art of medicine is gaining good intuition 219 00:13:23,520 --> 00:13:29,920 Speaker 3: and establishing sound processes to prioritize explanations in a reasonable 220 00:13:29,920 --> 00:13:33,000 Speaker 3: way based on what we know about frequency, but then 221 00:13:33,120 --> 00:13:36,600 Speaker 3: also to be able to catch the cases that are 222 00:13:36,760 --> 00:13:50,520 Speaker 3: unusual and intervene appropriately to help people. All right, you 223 00:13:50,520 --> 00:13:52,400 Speaker 3: want to talk a little bit about the evolution of 224 00:13:52,440 --> 00:13:53,079 Speaker 3: the horse hoof? 225 00:13:53,480 --> 00:13:55,120 Speaker 2: Yeah, yeah, we should probably talk a little bit more 226 00:13:55,160 --> 00:13:57,960 Speaker 2: about how they came to run about in their middle fingers. 227 00:13:58,760 --> 00:14:02,280 Speaker 3: We talked in the last episode about a pretty commonly 228 00:14:02,320 --> 00:14:06,720 Speaker 3: accepted story of how that evolutionary process occurred, but there 229 00:14:06,800 --> 00:14:11,439 Speaker 3: was still some uncertainty about exactly why the one toe 230 00:14:11,480 --> 00:14:14,600 Speaker 3: making contact with the ground is favored over keeping the 231 00:14:15,480 --> 00:14:18,400 Speaker 3: larger number of toes that the ancestors of horses used 232 00:14:18,400 --> 00:14:20,920 Speaker 3: to have, And to some degree, I think that question 233 00:14:21,040 --> 00:14:23,960 Speaker 3: is still not fully settled. There are still some questions 234 00:14:24,000 --> 00:14:27,280 Speaker 3: about why exactly the one toe was favored. We do 235 00:14:27,440 --> 00:14:30,240 Speaker 3: know that the ancestors of horses and zebras and asses 236 00:14:30,440 --> 00:14:34,680 Speaker 3: had multiple toes per foot, But what is gained by 237 00:14:34,680 --> 00:14:38,520 Speaker 3: going quad bird, you know, the middle fingers across all 238 00:14:38,520 --> 00:14:42,640 Speaker 3: four feet. So the evolution of is called monodactyly having 239 00:14:42,680 --> 00:14:46,840 Speaker 3: one toe Monodactyly, it has long been assumed that that 240 00:14:47,120 --> 00:14:51,200 Speaker 3: was useful for allowing a large animal like a modern horse, 241 00:14:51,280 --> 00:14:55,000 Speaker 3: to achieve greater running speed. But I came across an 242 00:14:55,040 --> 00:14:58,720 Speaker 3: interesting alternative idea explored in a paper called the Evolution 243 00:14:58,880 --> 00:15:03,280 Speaker 3: of equid monodact a review including a new hypothesis published 244 00:15:03,320 --> 00:15:07,600 Speaker 3: in Frontiers and Ecology and Evolution by Christine M. Janis 245 00:15:07,640 --> 00:15:12,000 Speaker 3: and Raymond Bernor. And basically here the authors ask what 246 00:15:12,280 --> 00:15:16,320 Speaker 3: if the evolution of the modern equine hoof was a 247 00:15:16,520 --> 00:15:22,440 Speaker 3: product of selection for endurance rather than speed, meaning that 248 00:15:22,560 --> 00:15:27,120 Speaker 3: the primary advantage conferred was in the evolution of an 249 00:15:27,200 --> 00:15:32,200 Speaker 3: efficient and energy efficient spring foot that would support long 250 00:15:32,280 --> 00:15:38,720 Speaker 3: distance trots at medium speed to locate better food resources. So, 251 00:15:39,440 --> 00:15:43,600 Speaker 3: under their hypothesis, the loss of extra toes may have 252 00:15:43,680 --> 00:15:47,840 Speaker 3: been a coincidental byproduct of the selection for the more 253 00:15:47,880 --> 00:15:53,200 Speaker 3: efficient spring foot, which helps the horse conserve energy while foraging, 254 00:15:54,240 --> 00:15:58,760 Speaker 3: rather than an adaptation for top speed running, which again 255 00:15:58,840 --> 00:16:01,600 Speaker 3: is assumed to be primarily for the purpose of escaping 256 00:16:01,640 --> 00:16:05,040 Speaker 3: the jaws of predators. Now, I cite this not to 257 00:16:05,080 --> 00:16:08,200 Speaker 3: say that I think their hypothesis is definitely correct. I 258 00:16:08,240 --> 00:16:11,640 Speaker 3: have no expertise to decide between which explanation of the 259 00:16:11,640 --> 00:16:15,960 Speaker 3: horstof evolution better fits the evidence. But this possibility made 260 00:16:16,000 --> 00:16:18,440 Speaker 3: me think back again to the Zebras on Green Street 261 00:16:18,520 --> 00:16:23,280 Speaker 3: saying about how sometimes certain explanations seem more likely to us, 262 00:16:23,400 --> 00:16:27,480 Speaker 3: not because they're actually more common, but because they're more 263 00:16:27,520 --> 00:16:31,400 Speaker 3: mentally salient. It reminds me I've talked before about this 264 00:16:31,640 --> 00:16:34,120 Speaker 3: idea that I have the sort of sex and violence 265 00:16:34,160 --> 00:16:38,560 Speaker 3: principle in evolutionary reasoning, where what I think I've observed 266 00:16:38,640 --> 00:16:43,680 Speaker 3: is that when people without or sometimes even with biological training, 267 00:16:44,080 --> 00:16:47,600 Speaker 3: are trying to think of possible evolutionary explanations for a 268 00:16:47,600 --> 00:16:51,280 Speaker 3: trait in an organism, we are a little too quick 269 00:16:51,480 --> 00:16:57,120 Speaker 3: to resort to explanations involving either predation or mating, and 270 00:16:57,240 --> 00:17:02,000 Speaker 3: we often overlook extremely common mechanism in nature, like temperature 271 00:17:02,080 --> 00:17:06,600 Speaker 3: regulation and energy efficiency, which play a huge role in 272 00:17:06,680 --> 00:17:09,800 Speaker 3: the success of a life form. But I think maybe 273 00:17:09,840 --> 00:17:14,160 Speaker 3: they're not as interesting to our brains as sex or violence, 274 00:17:14,359 --> 00:17:17,160 Speaker 3: so we're less likely to think of them. They do 275 00:17:17,200 --> 00:17:19,800 Speaker 3: not bleed, so they do not lead in the mind. 276 00:17:20,280 --> 00:17:22,440 Speaker 2: Yeah, it kind of reminds me of past discussions we've 277 00:17:22,440 --> 00:17:26,359 Speaker 2: talked about concerning the Stegosaurus, For example, you know, and 278 00:17:27,119 --> 00:17:29,520 Speaker 2: memory serves you know that there have been various interpretations 279 00:17:29,520 --> 00:17:32,520 Speaker 2: over the years, for there are those curious plates on 280 00:17:32,560 --> 00:17:36,200 Speaker 2: their back, as well as very interpretations of just how 281 00:17:36,200 --> 00:17:40,040 Speaker 2: they're positioned. But yeah, you can with something like that, 282 00:17:40,119 --> 00:17:42,760 Speaker 2: you can. You're inevitably you're going to find those explanations 283 00:17:42,840 --> 00:17:47,440 Speaker 2: that have to do with mating, or protection from predators, 284 00:17:47,520 --> 00:17:51,720 Speaker 2: or protection when they're in conflict with others of their kind. 285 00:17:52,200 --> 00:17:56,280 Speaker 2: But yeah, I guess sometimes these ideas that they're used 286 00:17:56,280 --> 00:17:59,359 Speaker 2: for temperature regulation or something like that may may feel 287 00:17:59,400 --> 00:18:03,200 Speaker 2: less excite, may feel more mundane. Though I guess you 288 00:18:03,240 --> 00:18:06,960 Speaker 2: could also argue that maybe the more exotic or mysterious 289 00:18:07,080 --> 00:18:11,960 Speaker 2: the feature is, like say those backridges on the stegosaurus, 290 00:18:12,680 --> 00:18:14,919 Speaker 2: maybe that cancels it out to some degree. I don't know, 291 00:18:15,320 --> 00:18:17,560 Speaker 2: but it's hard to imagine a like a seven year 292 00:18:17,560 --> 00:18:18,960 Speaker 2: old or an eight year old playing with the toy 293 00:18:19,000 --> 00:18:22,600 Speaker 2: Stegasaurus and be like, look, Mom and dad, this guy's 294 00:18:22,640 --> 00:18:26,120 Speaker 2: warming up in the sun watching. That's not what bathtub 295 00:18:26,119 --> 00:18:27,520 Speaker 2: dinosaurs do. They bite each other. 296 00:18:29,520 --> 00:18:31,200 Speaker 3: But again, I want to make clear, I'm not saying 297 00:18:31,240 --> 00:18:35,119 Speaker 3: I think that the the trotting foraging spring hoof explanation 298 00:18:36,000 --> 00:18:39,600 Speaker 3: is necessarily better than the high speed running explanation for 299 00:18:39,640 --> 00:18:41,760 Speaker 3: the horse hoof. I don't know, but I think it's 300 00:18:41,760 --> 00:18:45,840 Speaker 3: important to remember to consider those types of explanations as well. Now, 301 00:18:45,880 --> 00:18:50,399 Speaker 3: another question that has come up in several things I 302 00:18:50,440 --> 00:18:53,879 Speaker 3: was reading is about should we really say that the 303 00:18:53,920 --> 00:18:56,480 Speaker 3: horse only has one toe? I mean, it really does 304 00:18:56,600 --> 00:18:59,879 Speaker 3: basically have only one toe that makes contact with the 305 00:19:00,440 --> 00:19:03,680 Speaker 3: with the ground, But in what sense did it really 306 00:19:03,880 --> 00:19:07,960 Speaker 3: quote lose the other toes. One example of this counter 307 00:19:08,040 --> 00:19:11,359 Speaker 3: narrative I was reading is in an article in The 308 00:19:11,359 --> 00:19:15,280 Speaker 3: New York Times by Veronique Greenwood published February eighth, twenty twenty, 309 00:19:15,359 --> 00:19:18,360 Speaker 3: called a horse has five toes and then it doesn't. 310 00:19:18,720 --> 00:19:21,320 Speaker 3: And this article tells the story of a researcher named 311 00:19:21,400 --> 00:19:25,880 Speaker 3: Catherine Kavanaugh, a biologist at the University of Massachusetts Dartmouth, 312 00:19:26,280 --> 00:19:30,919 Speaker 3: who was looking at preserved horse embryos in the lab 313 00:19:31,280 --> 00:19:34,760 Speaker 3: when she discovered something very interesting, which is that during 314 00:19:34,840 --> 00:19:39,720 Speaker 3: the earliest stages of gestation, the area of the embryo 315 00:19:39,800 --> 00:19:43,439 Speaker 3: that will eventually develop to become the foot become the hoof. 316 00:19:44,320 --> 00:19:50,000 Speaker 3: In that area, the embryonic horses have five toes. So 317 00:19:50,160 --> 00:19:53,040 Speaker 3: this period during development only lasts for a couple of 318 00:19:53,119 --> 00:19:55,840 Speaker 3: days before the extra toes begin to sort of fuse 319 00:19:55,920 --> 00:19:59,440 Speaker 3: and vanish. But to read from the article briefly, quote 320 00:19:59,560 --> 00:20:03,800 Speaker 3: the discover reimplies something profound about how anatomical development works. 321 00:20:04,240 --> 00:20:07,720 Speaker 3: As an embryo puts itself together, growing from a tiny 322 00:20:07,800 --> 00:20:11,040 Speaker 3: wad of cells into multiple specialized tissues, fed by blood 323 00:20:11,119 --> 00:20:14,679 Speaker 3: vessels and linked by the winding threads of nerves, it 324 00:20:14,840 --> 00:20:18,640 Speaker 3: is following a template. That template is subject to evolution, 325 00:20:19,000 --> 00:20:22,200 Speaker 3: just like other things about the animal. But some moments 326 00:20:22,200 --> 00:20:25,680 Speaker 3: in the process or some routes that development takes may 327 00:20:25,720 --> 00:20:30,520 Speaker 3: not easily be altered. And so the researcher here, Catherine Kavanaugh, 328 00:20:30,560 --> 00:20:34,040 Speaker 3: is quoted saying something about the early steps in toe 329 00:20:34,160 --> 00:20:38,360 Speaker 3: development is stabilized. We don't know why, but that's what 330 00:20:38,400 --> 00:20:41,680 Speaker 3: we think is going on. So I found this also 331 00:20:41,720 --> 00:20:45,480 Speaker 3: interesting because it's an example of how stages in development 332 00:20:45,560 --> 00:20:50,719 Speaker 3: can become evolutionarily fixed even when they differ from the 333 00:20:50,760 --> 00:20:54,520 Speaker 3: final form. So like, for some reason, as the horse 334 00:20:54,640 --> 00:20:59,359 Speaker 3: is growing as an embryo, it needs to develop five 335 00:20:59,560 --> 00:21:03,840 Speaker 3: fingers before or five toes before it can lose four 336 00:21:03,880 --> 00:21:07,600 Speaker 3: of the toes per hoof, so you know, eventually it 337 00:21:07,640 --> 00:21:10,760 Speaker 3: will have functionally one toe making contact with the ground, 338 00:21:11,080 --> 00:21:14,520 Speaker 3: but the development process has to go through this other 339 00:21:14,640 --> 00:21:15,560 Speaker 3: stage first. 340 00:21:15,680 --> 00:21:18,960 Speaker 2: For some reason, it reminds me of something we discussed 341 00:21:18,960 --> 00:21:21,280 Speaker 2: in our whale episodes about the blowhole of the whale 342 00:21:21,640 --> 00:21:25,000 Speaker 2: being seen to, of course, through the fossil record, travel 343 00:21:25,160 --> 00:21:26,800 Speaker 2: up the snout up to the top of the head. 344 00:21:26,840 --> 00:21:29,680 Speaker 2: But we can also observe this movement in the womb 345 00:21:30,040 --> 00:21:32,760 Speaker 2: as the fetal whale is developing. 346 00:21:33,440 --> 00:21:38,159 Speaker 3: Yeah. Another interesting thing about the horse hoof is that 347 00:21:38,240 --> 00:21:41,200 Speaker 3: there are some people who have pointed out how vestiges 348 00:21:41,400 --> 00:21:44,760 Speaker 3: of the missing toes can still sort of be found 349 00:21:44,840 --> 00:21:48,040 Speaker 3: as little sort of ridges on the sides of the hoof. 350 00:21:48,400 --> 00:21:50,119 Speaker 2: Yeah. I ran across this a lot in some of 351 00:21:50,160 --> 00:21:53,720 Speaker 2: the veterinary sources I was looking at. 352 00:21:53,920 --> 00:21:56,440 Speaker 3: But don't let this take away from your mental enjoyment 353 00:21:56,480 --> 00:21:59,280 Speaker 3: of thinking about the horses running around on its middle fingers, 354 00:21:59,320 --> 00:22:01,160 Speaker 3: which functionally is it is? 355 00:22:01,720 --> 00:22:03,600 Speaker 2: I mean to me, it makes it even more weird. 356 00:22:04,040 --> 00:22:05,840 Speaker 2: It's kind of like if you were to It's kind 357 00:22:05,840 --> 00:22:08,240 Speaker 2: of like if you're looking at Kermit the frog and 358 00:22:08,320 --> 00:22:10,760 Speaker 2: someone were to tell you, like there's a difference in saying, hey, 359 00:22:10,800 --> 00:22:14,360 Speaker 2: there's somebody's hand in there and and someone saying, actually, 360 00:22:14,720 --> 00:22:16,960 Speaker 2: all the bones of a human hand are present in 361 00:22:17,040 --> 00:22:20,560 Speaker 2: Kermit the frog, but they have been repurposed and formed 362 00:22:20,840 --> 00:22:25,000 Speaker 2: into the skeletal structure of this bipedal frog creature. Like 363 00:22:25,040 --> 00:22:27,879 Speaker 2: that's even crazier, and I feel like that's more in 364 00:22:27,920 --> 00:22:30,159 Speaker 2: line with what we know about the horses. 365 00:22:30,840 --> 00:22:32,000 Speaker 3: Splendid analogy. 366 00:22:32,119 --> 00:22:32,520 Speaker 2: Bravo. 367 00:22:33,359 --> 00:22:36,640 Speaker 3: All right, are we ready to talk about the horse shoe? 368 00:22:37,080 --> 00:22:40,760 Speaker 2: Yeah, this is something that originally I didn't think we 369 00:22:40,760 --> 00:22:43,080 Speaker 2: were going to cover, or if we were to cover, 370 00:22:43,200 --> 00:22:45,200 Speaker 2: we might come back, but I felt like it's kind 371 00:22:45,200 --> 00:22:48,399 Speaker 2: of so closely linked to our understanding of the horse 372 00:22:48,440 --> 00:22:51,119 Speaker 2: and the human use of the horse. And at the 373 00:22:51,160 --> 00:22:53,320 Speaker 2: same time, in discussing this, we are going to be 374 00:22:53,359 --> 00:22:59,320 Speaker 2: kind of blowing through the domestication of the horse rather quickly. 375 00:22:59,840 --> 00:23:02,920 Speaker 2: Like this is a topic that has received a lot 376 00:23:02,960 --> 00:23:07,000 Speaker 2: of attention over the years in varying fields. I mean, 377 00:23:07,480 --> 00:23:12,920 Speaker 2: there's genetic research, there's archaeology, there's you know, various cultural inquiries. 378 00:23:14,240 --> 00:23:15,679 Speaker 2: It's kind of all over the place, and there are 379 00:23:15,680 --> 00:23:17,880 Speaker 2: a lot of unanswered questions about you know, especially when 380 00:23:17,920 --> 00:23:21,080 Speaker 2: you get into you know, the exact who's and winds 381 00:23:21,160 --> 00:23:24,720 Speaker 2: and wares, say horse domestication, and even the development or 382 00:23:24,720 --> 00:23:28,800 Speaker 2: the horseshoe. But I feel like covering the horseshoe also 383 00:23:28,840 --> 00:23:31,879 Speaker 2: helps us understand the hoof a little bit more so, 384 00:23:32,160 --> 00:23:35,800 Speaker 2: briefly talking about the modern horse, the modern horse has 385 00:23:35,800 --> 00:23:39,800 Speaker 2: a long and pivotal history as a human steed. Many 386 00:23:39,840 --> 00:23:43,400 Speaker 2: animals have, of course served as mounts for human riders, 387 00:23:43,840 --> 00:23:47,119 Speaker 2: and many have served as a pack and draft animals. 388 00:23:47,680 --> 00:23:49,920 Speaker 2: I know that, at least on the Artifact and perhaps 389 00:23:49,960 --> 00:23:52,320 Speaker 2: elsewhere in some core episodes, we've touched on the importance 390 00:23:52,320 --> 00:23:55,720 Speaker 2: of the camel and the donkey, But the horse, the 391 00:23:55,800 --> 00:23:58,720 Speaker 2: horse is just a whole different matter, both in terms 392 00:23:58,760 --> 00:24:01,240 Speaker 2: of like the impact that it's had, like I think 393 00:24:01,280 --> 00:24:04,840 Speaker 2: the larger impact that it's had globally, and also just 394 00:24:05,240 --> 00:24:08,959 Speaker 2: how it has captured the imagination. Not to diminish the 395 00:24:09,000 --> 00:24:11,960 Speaker 2: camel or the donkey, because in particular regions, the camel 396 00:24:12,000 --> 00:24:15,080 Speaker 2: and the donkey have been far more important. Whole books 397 00:24:15,119 --> 00:24:17,280 Speaker 2: have been written about the camel and the donkey, and 398 00:24:17,520 --> 00:24:19,719 Speaker 2: I've read parts of them. If you want to hear 399 00:24:19,720 --> 00:24:21,200 Speaker 2: a little bit more about that, go back to the 400 00:24:21,680 --> 00:24:24,920 Speaker 2: Monster Fact episode that I did on Donkeys of Dune, 401 00:24:25,280 --> 00:24:28,520 Speaker 2: which touched on this a little bit. Now, as we've discussed, 402 00:24:28,600 --> 00:24:31,840 Speaker 2: the modern horse evolved over the course of fifty to 403 00:24:31,880 --> 00:24:36,879 Speaker 2: sixty million years from a diminutive ancestor, and then it 404 00:24:37,080 --> 00:24:40,640 Speaker 2: would have reached identifiable form somewhere around four to four 405 00:24:40,720 --> 00:24:44,240 Speaker 2: point five million years ago, then migrating across the Bearing 406 00:24:44,280 --> 00:24:47,760 Speaker 2: Straight via some sort of a primitive land bridge into 407 00:24:47,800 --> 00:24:51,399 Speaker 2: Eurasia about eleven thousand years ago, and becoming stinct in 408 00:24:51,640 --> 00:24:54,720 Speaker 2: North America after that, and it would not come back 409 00:24:54,760 --> 00:24:58,520 Speaker 2: around the globe to North America until it was reintroduced 410 00:24:58,840 --> 00:25:03,000 Speaker 2: the European conc West in the fifteenth century see now. 411 00:25:03,040 --> 00:25:06,760 Speaker 2: Of the wild horse's three ancestors, two when extinct, and 412 00:25:06,840 --> 00:25:12,119 Speaker 2: a third the takei or Mongolian wild horse or Preswalski's horse, 413 00:25:12,800 --> 00:25:15,320 Speaker 2: these are all the different names for the same creature. Essentially, 414 00:25:16,080 --> 00:25:19,320 Speaker 2: this survived only in captivity and then was subsequently has 415 00:25:19,359 --> 00:25:23,040 Speaker 2: been subsequently reintroduced into the wild, though with some important 416 00:25:23,040 --> 00:25:26,800 Speaker 2: caveats worth discussing. Should we come back around to talk 417 00:25:26,840 --> 00:25:30,639 Speaker 2: about the reintroduction of a species. There are lots of 418 00:25:30,640 --> 00:25:32,760 Speaker 2: sort of ups and downs with that particular story, as 419 00:25:32,800 --> 00:25:36,760 Speaker 2: there are with some other species reintroduction tales. Now much 420 00:25:36,800 --> 00:25:38,320 Speaker 2: has been written about the role of the horse in 421 00:25:38,359 --> 00:25:40,879 Speaker 2: the history of human conflict, and there is indeed just 422 00:25:40,960 --> 00:25:44,200 Speaker 2: so much that we we could and I guess should 423 00:25:44,240 --> 00:25:48,240 Speaker 2: one day discuss about that, you know, the use of say, 424 00:25:48,359 --> 00:25:52,400 Speaker 2: chariot technology, even the saddle like, they're just so many 425 00:25:52,400 --> 00:25:56,600 Speaker 2: different angles to take. Now. Its pointed out by equine 426 00:25:56,640 --> 00:25:59,960 Speaker 2: warfare expert A Highland and this is in Brian fahe 427 00:26:00,040 --> 00:26:03,840 Speaker 2: against the Seventy Great Inventions of the Ancient World. DNA 428 00:26:03,920 --> 00:26:07,119 Speaker 2: evidence suggests that the domestication of the horse took place 429 00:26:07,359 --> 00:26:12,480 Speaker 2: independently in several different places and times. And according to them, 430 00:26:12,480 --> 00:26:14,240 Speaker 2: and this was this book came out in two thousand 431 00:26:14,240 --> 00:26:16,360 Speaker 2: and four, so I'm going to touch in a more 432 00:26:16,480 --> 00:26:20,800 Speaker 2: recent source on all this in just a second. They 433 00:26:20,920 --> 00:26:24,240 Speaker 2: were talking about the earliest domestication having possibly taken place 434 00:26:24,440 --> 00:26:28,760 Speaker 2: on the Eurasian Step somewhere around four thousand BCE, though 435 00:26:28,800 --> 00:26:32,520 Speaker 2: they did highlight that the proof was inconclusive. I've also 436 00:26:32,640 --> 00:26:35,119 Speaker 2: seen other sources just put it that the geographic origin 437 00:26:35,160 --> 00:26:38,439 Speaker 2: of horse domestication is simply an unknown and there of 438 00:26:38,480 --> 00:26:41,760 Speaker 2: course a handful of likely areas and times, based on 439 00:26:41,800 --> 00:26:45,800 Speaker 2: different findings, spread across Eurasia from as far west as 440 00:26:45,840 --> 00:26:49,720 Speaker 2: Iberia to as far east as Siberia now more recently. 441 00:26:49,760 --> 00:26:51,680 Speaker 2: The more recent source I was looking at on this though, 442 00:26:51,800 --> 00:26:55,320 Speaker 2: was a twenty twenty one analysis of ancient horse DNA, 443 00:26:56,080 --> 00:26:57,800 Speaker 2: and this seemed to narrow it down to the Eurasian 444 00:26:57,840 --> 00:27:01,720 Speaker 2: step the Volga Dawn region, so that would seem to 445 00:27:01,840 --> 00:27:05,760 Speaker 2: possibly be the strong contender for where the who. That's 446 00:27:05,760 --> 00:27:08,879 Speaker 2: a little bit more complex, is pointed out by Amber 447 00:27:09,040 --> 00:27:12,160 Speaker 2: Dance in a solid twenty twenty two article for Smithsonian 448 00:27:12,200 --> 00:27:15,919 Speaker 2: Magazine titled When Did Humans Domesticate the Horse? The region 449 00:27:16,080 --> 00:27:18,960 Speaker 2: was home to diverse peoples who may have engaged in 450 00:27:19,000 --> 00:27:22,919 Speaker 2: horse domestication, and the earliest time period the win in 451 00:27:22,960 --> 00:27:26,680 Speaker 2: all of this sounds like it was maybe four two 452 00:27:26,720 --> 00:27:30,160 Speaker 2: hundred years ago, pushing us back to the twenty one 453 00:27:30,200 --> 00:27:33,080 Speaker 2: hundred s BCE. Based on all of this, though, Dance 454 00:27:33,119 --> 00:27:36,240 Speaker 2: also points out that quote clear evidence of horse domestication 455 00:27:36,359 --> 00:27:40,120 Speaker 2: doesn't appear in the archaeological record until about five five 456 00:27:40,160 --> 00:27:43,840 Speaker 2: hundred years ago, and that would push things back obviously now. 457 00:27:43,840 --> 00:27:47,160 Speaker 2: As Highland and Fagan pointed out, stud records from twenty 458 00:27:47,200 --> 00:27:49,760 Speaker 2: three hundred BC and what is now a RAQ include 459 00:27:49,920 --> 00:27:54,040 Speaker 2: data on donkeys, mules, and some horses. There are Sumerian 460 00:27:54,119 --> 00:27:57,440 Speaker 2: proverbs that refer to horse riding during this time period. 461 00:27:58,440 --> 00:28:00,680 Speaker 2: But yeah, like I say, this is topic we could 462 00:28:00,720 --> 00:28:04,359 Speaker 2: go on about at some length, but suffice to say 463 00:28:04,400 --> 00:28:08,439 Speaker 2: that the evidence points to this general time period, but 464 00:28:08,520 --> 00:28:20,560 Speaker 2: it has still long been a topic of dispute. Now, 465 00:28:20,960 --> 00:28:23,480 Speaker 2: one thing that I liked in Dance's article is that 466 00:28:23,520 --> 00:28:27,439 Speaker 2: they point out that horses were coexisting alongside human beings 467 00:28:27,840 --> 00:28:31,439 Speaker 2: long before we were able to ride them or really 468 00:28:31,480 --> 00:28:35,080 Speaker 2: do anything with them. They were around during the time 469 00:28:35,080 --> 00:28:38,680 Speaker 2: of Stone Age human beings. They no doubt inspired Stone 470 00:28:38,720 --> 00:28:43,160 Speaker 2: Age human beings and human populations. Our ancestors depicted them 471 00:28:43,160 --> 00:28:45,560 Speaker 2: in their cave art, but it would have been a 472 00:28:45,600 --> 00:28:48,560 Speaker 2: long time before they could figure out how to master 473 00:28:48,720 --> 00:28:52,120 Speaker 2: these beasts and truly harness the power of the horse. Yeah. 474 00:28:52,160 --> 00:28:54,080 Speaker 3: I don't know if this is still the dominant view, 475 00:28:54,200 --> 00:28:58,800 Speaker 3: but I recall reading years ago that many researchers thought 476 00:28:58,840 --> 00:29:04,000 Speaker 3: that humans probably hunted horses for food before they domesticated them. 477 00:29:04,280 --> 00:29:07,560 Speaker 2: Yeah, that's that's what I saw indicated, and these sources 478 00:29:07,560 --> 00:29:09,480 Speaker 2: I was looking at as well, you know, I mean, 479 00:29:09,720 --> 00:29:11,720 Speaker 2: you see them from afar. They look cool, They looked 480 00:29:11,720 --> 00:29:13,800 Speaker 2: really neat. Look at that those flowing manes. I mean, 481 00:29:14,000 --> 00:29:17,000 Speaker 2: it's kind of interesting to think that some of the 482 00:29:17,080 --> 00:29:20,680 Speaker 2: some of the impressions we have watching a horse running 483 00:29:20,720 --> 00:29:24,520 Speaker 2: about with its kind, you know, across the field. You know, 484 00:29:25,200 --> 00:29:27,920 Speaker 2: maybe we're feeling some of the same things our ancient 485 00:29:27,960 --> 00:29:30,280 Speaker 2: ancestors would have felt, you know, these sort of deep 486 00:29:30,320 --> 00:29:34,400 Speaker 2: down impressions, but with the added level of we probably 487 00:29:34,400 --> 00:29:37,840 Speaker 2: don't think about maybe running them down with our spears 488 00:29:38,000 --> 00:29:41,200 Speaker 2: and cooking them up later and making things out of them. 489 00:29:41,200 --> 00:29:43,280 Speaker 2: But of course this would have been This was how 490 00:29:43,360 --> 00:29:47,959 Speaker 2: we interacted with pretty much everything in the natural world 491 00:29:48,480 --> 00:29:51,040 Speaker 2: during that time period. And of course if we were 492 00:29:51,080 --> 00:29:52,760 Speaker 2: going to hunt a horse, we would have to depend 493 00:29:52,840 --> 00:29:58,640 Speaker 2: on human ingenuity, human strategy, human tool use, and eventually 494 00:29:58,680 --> 00:30:01,800 Speaker 2: when humans figure out about how to truly harness the horse, 495 00:30:02,640 --> 00:30:07,000 Speaker 2: they also had to employ various tools. So if anyone 496 00:30:07,000 --> 00:30:10,560 Speaker 2: out there, if you're like me, most of your experience 497 00:30:10,680 --> 00:30:13,560 Speaker 2: with horses is probably in video games where you you 498 00:30:13,600 --> 00:30:16,840 Speaker 2: break a wild horse or train a wild horse by 499 00:30:16,880 --> 00:30:19,080 Speaker 2: doing something like I don't know, whistling at it, or 500 00:30:19,880 --> 00:30:22,120 Speaker 2: you know, you jump up on its back. I was 501 00:30:22,120 --> 00:30:23,760 Speaker 2: asking my son, how do you how do you get 502 00:30:23,800 --> 00:30:25,480 Speaker 2: a horse and Zelden, He's like, oh, you just jump 503 00:30:25,480 --> 00:30:27,000 Speaker 2: on its back and I don't know, you do something 504 00:30:27,000 --> 00:30:28,120 Speaker 2: else and then you're good to go. 505 00:30:28,520 --> 00:30:31,080 Speaker 3: Yeah, And Breath of the Wild is kind of a 506 00:30:31,080 --> 00:30:33,400 Speaker 3: bucking Bronco thing. You jump on the horse and if 507 00:30:33,440 --> 00:30:35,520 Speaker 3: you can hold on long enough while it's trying to 508 00:30:35,600 --> 00:30:37,200 Speaker 3: kick you off, then it becomes your friend. 509 00:30:37,600 --> 00:30:40,240 Speaker 2: There you go. Yeah, then that's fine for video game, 510 00:30:40,320 --> 00:30:42,880 Speaker 2: but the reality is a lot more complex. If you 511 00:30:42,920 --> 00:30:47,440 Speaker 2: read any like serious westerns about breaking horses and so forth, 512 00:30:47,480 --> 00:30:51,480 Speaker 2: you get into a little Cornick McCarthy, you're gonna you know, 513 00:30:51,520 --> 00:30:55,920 Speaker 2: it's it's it's a longer process, a lot more more kicking, 514 00:30:56,600 --> 00:31:00,560 Speaker 2: maybe a few more busted ribs in the process. And 515 00:31:00,640 --> 00:31:03,160 Speaker 2: so one thing that Highland and Fagan point out is 516 00:31:03,200 --> 00:31:07,800 Speaker 2: that as humans were mastering horses, they inevitably turned to 517 00:31:07,960 --> 00:31:13,160 Speaker 2: bovine control mechanisms, so cows were domesticated much earlier. Humans 518 00:31:13,200 --> 00:31:15,720 Speaker 2: had much earlier figured out some of the ways that 519 00:31:15,720 --> 00:31:20,520 Speaker 2: they could use tools and things they built to control 520 00:31:20,800 --> 00:31:24,360 Speaker 2: these large and powerful creatures, and they were able to 521 00:31:24,360 --> 00:31:27,000 Speaker 2: adapt some of those for the domestication of the horse, 522 00:31:27,440 --> 00:31:29,720 Speaker 2: and they evolved from there to include things like metal 523 00:31:29,760 --> 00:31:33,920 Speaker 2: bits and harnesses, ultimately things like armor, horse armor for battle, 524 00:31:34,640 --> 00:31:38,600 Speaker 2: chariot technology, and of course things like the saddle and 525 00:31:38,680 --> 00:31:41,840 Speaker 2: stirrup loops. But all of this discussion thus far has 526 00:31:41,880 --> 00:31:44,280 Speaker 2: been in service of the horse hoof and of course 527 00:31:44,720 --> 00:31:49,160 Speaker 2: the horseshoe. As we mentioned already in the previous episode 528 00:31:49,200 --> 00:31:52,320 Speaker 2: on the horse hoof, the hoof, while certainly an amazing adaptation, 529 00:31:53,000 --> 00:31:56,360 Speaker 2: is not indestructible, and the domestication of the horse took 530 00:31:56,480 --> 00:31:59,160 Speaker 2: this creature out of its sort of normal environment and 531 00:32:00,280 --> 00:32:03,880 Speaker 2: in activities and placed it in those that suited us best, 532 00:32:04,320 --> 00:32:09,320 Speaker 2: especially in the use of things like agriculture, travel, ultimately warfare, 533 00:32:09,760 --> 00:32:12,880 Speaker 2: and at some point, and much like horse domestication itself, 534 00:32:13,040 --> 00:32:17,680 Speaker 2: likely various points in various times in ancient history, humans 535 00:32:17,720 --> 00:32:20,720 Speaker 2: who made use of the horse realize that hoofs require 536 00:32:21,000 --> 00:32:24,400 Speaker 2: special care, and that this care could in fact be 537 00:32:25,160 --> 00:32:29,000 Speaker 2: preventative care, so the hoof, like the human foot, could 538 00:32:29,080 --> 00:32:31,160 Speaker 2: be protected and reinforced. 539 00:32:31,600 --> 00:32:35,320 Speaker 3: This is one of those things like drinking animal milk. 540 00:32:35,440 --> 00:32:38,360 Speaker 3: That's the questions like, who's the first person who tried 541 00:32:38,400 --> 00:32:41,160 Speaker 3: to do this? You really got to wonder. 542 00:32:41,120 --> 00:32:43,240 Speaker 2: Yeah, and again this kind of gets into sort of 543 00:32:43,280 --> 00:32:47,960 Speaker 2: the everyday nature of the horse and horse related technology. 544 00:32:48,240 --> 00:32:51,280 Speaker 2: It just seems so common. You know, it's the stuff 545 00:32:51,280 --> 00:32:55,400 Speaker 2: of Westerns and fantasy shows, fantasy shows in which the 546 00:32:55,480 --> 00:32:58,600 Speaker 2: horse is not the most fantastic element. You know, we're 547 00:32:58,600 --> 00:33:02,600 Speaker 2: focusing on the dragon, but while here's this animal running 548 00:33:02,600 --> 00:33:05,800 Speaker 2: around on its on its single toes, and we have 549 00:33:06,240 --> 00:33:10,840 Speaker 2: augmented this creature with various contraptions and straps and bits. 550 00:33:10,920 --> 00:33:16,280 Speaker 2: And also we have we have nailed these these shoes. 551 00:33:16,440 --> 00:33:17,800 Speaker 2: We call them a shoe, but you know, it's like 552 00:33:17,920 --> 00:33:21,040 Speaker 2: it's like an iron loop onto the bottom of their 553 00:33:21,080 --> 00:33:25,080 Speaker 2: their hoof walls in order to make them more capable 554 00:33:25,120 --> 00:33:27,280 Speaker 2: of keeping up with what we need them to do. 555 00:33:28,080 --> 00:33:33,400 Speaker 2: Technologically enhanced. Is the horse cyborgs? Yeah, yeah, yeah, and 556 00:33:34,080 --> 00:33:38,760 Speaker 2: in some respects now, there have been many different approaches 557 00:33:38,800 --> 00:33:41,120 Speaker 2: to to this over the ages, because again, like the 558 00:33:41,160 --> 00:33:44,640 Speaker 2: basic nut of it is the realization that oh man, 559 00:33:44,680 --> 00:33:47,920 Speaker 2: we're rough on these horses. We should we're having to 560 00:33:48,040 --> 00:33:50,560 Speaker 2: like clean up and and take care of them after 561 00:33:50,600 --> 00:33:53,960 Speaker 2: we we use them too hard. Let's try and protect 562 00:33:53,960 --> 00:33:55,880 Speaker 2: that hoof a little bit. And there have been various 563 00:33:55,920 --> 00:33:58,600 Speaker 2: ways to sort of address this again in different times, 564 00:33:58,600 --> 00:34:02,080 Speaker 2: in different places. Some early examples from parts of Asia 565 00:34:02,120 --> 00:34:07,200 Speaker 2: have been based in apparently in medicinal organic wrappings to 566 00:34:07,280 --> 00:34:11,000 Speaker 2: treat injuries. So you're working your horse too hard, the 567 00:34:11,040 --> 00:34:15,240 Speaker 2: horse is suffering various injuries or ailments of the hoof, 568 00:34:15,440 --> 00:34:18,160 Speaker 2: so you start wrapping it up in things to protect 569 00:34:18,239 --> 00:34:22,080 Speaker 2: it and to heal it. And then it seems to 570 00:34:22,080 --> 00:34:26,359 Speaker 2: be a case of treatment becoming preventative, where it's realized, oh, 571 00:34:26,400 --> 00:34:29,200 Speaker 2: you know, let's just keep something wrapped around the hoof 572 00:34:30,000 --> 00:34:32,160 Speaker 2: or at least when we're using the horse, or at 573 00:34:32,239 --> 00:34:36,439 Speaker 2: least in certain environmental circumstances, and that can help make 574 00:34:36,480 --> 00:34:37,760 Speaker 2: the hoof last longer. 575 00:34:38,120 --> 00:34:38,960 Speaker 3: That's interesting. 576 00:34:39,400 --> 00:34:43,960 Speaker 2: Then there's this whole area of early hoof boots. Now 577 00:34:44,160 --> 00:34:46,240 Speaker 2: these are not to be confused with the hoof boots. 578 00:34:46,520 --> 00:34:50,600 Speaker 2: Humans make and wear themselves so that their own feet 579 00:34:50,680 --> 00:34:53,279 Speaker 2: can look like hoofs. If you're not familiar with these, 580 00:34:53,320 --> 00:34:56,319 Speaker 2: treat yourself, go do an image search. A lot of 581 00:34:56,320 --> 00:35:00,480 Speaker 2: them are cloven hoofs for like sator costumes. Other times 582 00:35:00,480 --> 00:35:03,400 Speaker 2: they are horse hoofs for horse related dress. 583 00:35:04,440 --> 00:35:06,560 Speaker 3: When you first, I didn't realize. At first you meant 584 00:35:06,600 --> 00:35:10,319 Speaker 3: like that these were for costumes, are recreational. I was like, 585 00:35:10,360 --> 00:35:13,200 Speaker 3: what is the functional reason to make your foot into 586 00:35:13,239 --> 00:35:14,440 Speaker 3: a hoof to. 587 00:35:14,440 --> 00:35:17,880 Speaker 2: Be a satyr or to be a horsey, and you find, 588 00:35:18,239 --> 00:35:20,080 Speaker 2: you know, some of them are very goth looking, some 589 00:35:20,120 --> 00:35:21,640 Speaker 2: of them more and more on the furry end of 590 00:35:21,640 --> 00:35:24,760 Speaker 2: the spectrum. But yeah, I saw some of these recently 591 00:35:24,880 --> 00:35:27,200 Speaker 2: at a at a Renaissance festival that I went to 592 00:35:27,239 --> 00:35:30,600 Speaker 2: with my family. There's a sador guy over there walking 593 00:35:30,600 --> 00:35:31,640 Speaker 2: around on hoof boots. 594 00:35:32,000 --> 00:35:34,040 Speaker 3: Man, you think being in high heels for a long 595 00:35:34,080 --> 00:35:36,879 Speaker 3: time is rough? It turn your foot into a hoof. 596 00:35:37,200 --> 00:35:41,120 Speaker 2: I know it does. It looks it looks unpleasant, I 597 00:35:41,160 --> 00:35:43,880 Speaker 2: mean it, but it's I guess it's like really awesome 598 00:35:43,960 --> 00:35:47,040 Speaker 2: high heels, right, I mean, nobody's wearing those for comfort. 599 00:35:47,040 --> 00:35:50,120 Speaker 2: You're wearing them to look cool. And the same goes 600 00:35:50,160 --> 00:35:52,560 Speaker 2: for those those weird goat boots you might be wearing 601 00:35:52,560 --> 00:35:54,839 Speaker 2: to the ren fest. All right. So what we're talking 602 00:35:54,880 --> 00:35:57,040 Speaker 2: about here not not those to sorts of hoof boots. 603 00:35:57,040 --> 00:36:00,200 Speaker 2: These are basically different approaches where you would take like 604 00:36:00,880 --> 00:36:05,600 Speaker 2: essentially like a leather sheath for the hoof, sometimes augmented 605 00:36:05,640 --> 00:36:08,400 Speaker 2: with metal studs on the bottom, essentially making you know, 606 00:36:08,440 --> 00:36:12,560 Speaker 2: you think about basically the same sort of adaptations you 607 00:36:12,600 --> 00:36:14,799 Speaker 2: would make to a human boot. You know, well, it's like, 608 00:36:15,440 --> 00:36:17,759 Speaker 2: let's wrap that foot up in leather, or it's a 609 00:36:17,760 --> 00:36:20,400 Speaker 2: little slippery, let's put some studs on the bottom of 610 00:36:20,400 --> 00:36:23,120 Speaker 2: that so it doesn't slip around. And it's also worth 611 00:36:23,160 --> 00:36:28,279 Speaker 2: noting that modern hoof boots exist as horseshoe alternatives. You 612 00:36:28,320 --> 00:36:30,759 Speaker 2: see a lot of this, particularly in the realm of 613 00:36:30,840 --> 00:36:36,640 Speaker 2: natural horsemanship, sort of like modern backing away from some 614 00:36:36,719 --> 00:36:42,560 Speaker 2: of the the aspects of horsemanship that might be, you know, 615 00:36:42,560 --> 00:36:45,440 Speaker 2: considered a little bit too rough or unnecessarily rough, especially 616 00:36:45,520 --> 00:36:47,400 Speaker 2: for what we might be asking of our horses in 617 00:36:47,440 --> 00:36:50,960 Speaker 2: the modern age, and so you might see a hoof boot, 618 00:36:51,120 --> 00:36:52,880 Speaker 2: which in many of these cases they look like like 619 00:36:53,080 --> 00:36:57,000 Speaker 2: little like sports shoes for a horse. They can slip 620 00:36:57,040 --> 00:36:59,239 Speaker 2: those on, and I'm to understand that also sometimes they're 621 00:36:59,320 --> 00:37:03,000 Speaker 2: used in a dish to a normal horseshoe. Equestrians out 622 00:37:03,000 --> 00:37:05,800 Speaker 2: there listening to the episode, if you have some thoughts 623 00:37:05,800 --> 00:37:08,759 Speaker 2: on hoof boots right in, we would love to see them. 624 00:37:09,880 --> 00:37:12,520 Speaker 2: Same goes for people who just like dressing like satyrs. 625 00:37:12,920 --> 00:37:15,120 Speaker 2: We also want to see your hoof boots. Nobody needs 626 00:37:15,120 --> 00:37:17,840 Speaker 2: to feel left out. But then there's also the hippo 627 00:37:17,960 --> 00:37:20,640 Speaker 2: sandal and this is exactly what it sounds like. It 628 00:37:20,719 --> 00:37:25,480 Speaker 2: is a sandal of sorts for horse hoofs These were 629 00:37:25,560 --> 00:37:30,359 Speaker 2: especially common in the Northwestern Roman Empire and it was 630 00:37:30,719 --> 00:37:33,360 Speaker 2: I think largely a temporary solution. So the idea is 631 00:37:33,400 --> 00:37:35,319 Speaker 2: this is not something that was nailed on. It was 632 00:37:35,360 --> 00:37:38,840 Speaker 2: something that was strapped on, and if you look at examples, 633 00:37:38,880 --> 00:37:41,600 Speaker 2: it looks like basically like a strap on horse hoof. 634 00:37:41,640 --> 00:37:44,319 Speaker 2: You can see that like these were generally made out 635 00:37:44,320 --> 00:37:47,680 Speaker 2: of iron. They would cover the bottom of the hoof 636 00:37:47,719 --> 00:37:51,000 Speaker 2: wall and then you would strap it on, but it 637 00:37:51,040 --> 00:37:54,319 Speaker 2: wasn't going to be on their long term. Once you 638 00:37:54,400 --> 00:37:56,839 Speaker 2: got wherever you were riding to, or I don't know, 639 00:37:56,880 --> 00:38:00,000 Speaker 2: after battle or whatever the scenario is, then it's time 640 00:38:00,080 --> 00:38:03,840 Speaker 2: to take these hippo sandals off. And then eventually we 641 00:38:03,920 --> 00:38:07,480 Speaker 2: get to the proper iron horseshoe, which everyone knows what 642 00:38:07,520 --> 00:38:11,040 Speaker 2: this looks like. Because it exists in the public mind 643 00:38:11,160 --> 00:38:15,200 Speaker 2: outside of mere equestrian interests, and even outside of its 644 00:38:15,320 --> 00:38:18,080 Speaker 2: use on the horse, it has become an artifact of 645 00:38:18,120 --> 00:38:22,080 Speaker 2: some significance across multiple cultures. It is this U shaped 646 00:38:22,080 --> 00:38:26,960 Speaker 2: twist of iron that is actually nailed into place in 647 00:38:27,000 --> 00:38:32,040 Speaker 2: the horse's hoof falls. The origin of this particular invention 648 00:38:32,239 --> 00:38:36,000 Speaker 2: or artifact is also difficult to well nail down, I 649 00:38:36,440 --> 00:38:40,160 Speaker 2: guess you could say, with different possibilities emerging. I've read 650 00:38:40,200 --> 00:38:43,520 Speaker 2: that the gulls are thought to have possibly innovated this. 651 00:38:43,760 --> 00:38:47,360 Speaker 2: Others have said the Celts may have done it, or 652 00:38:47,400 --> 00:38:50,839 Speaker 2: being among the first to do it, and there's some 653 00:38:50,920 --> 00:38:54,640 Speaker 2: evidence stemming from ancient grave sites. But one thing to 654 00:38:54,680 --> 00:38:57,480 Speaker 2: keep in mind here is that initially you might think, oh, well, 655 00:38:57,480 --> 00:38:59,680 Speaker 2: they're made out of iron, at least they're going to 656 00:38:59,760 --> 00:39:02,680 Speaker 2: keep longer. But then we have to realize iron would 657 00:39:02,680 --> 00:39:06,560 Speaker 2: have been precious, and therefore iron would often be reused 658 00:39:06,680 --> 00:39:10,759 Speaker 2: or even re forged, thus robbing us of evidence in 659 00:39:10,800 --> 00:39:15,440 Speaker 2: many cases of these particular artifacts. But it's possible that 660 00:39:15,480 --> 00:39:19,520 Speaker 2: the use of iron horseshoes go back to perhaps four 661 00:39:19,600 --> 00:39:22,680 Speaker 2: hundred BCE. But like a lot of this, the use 662 00:39:22,719 --> 00:39:25,680 Speaker 2: of iron horseshoes is rather broadly difficult to define and 663 00:39:26,400 --> 00:39:30,080 Speaker 2: nail down because their use often bumps up against and 664 00:39:30,120 --> 00:39:35,360 Speaker 2: coexists with other forms of protecting the hoof. So you 665 00:39:35,440 --> 00:39:38,080 Speaker 2: might have like a period of time and a part 666 00:39:38,080 --> 00:39:40,880 Speaker 2: of the world where some people are using a horseshoe, 667 00:39:41,160 --> 00:39:46,200 Speaker 2: some are using the hippo sandal or some other innovation, 668 00:39:46,760 --> 00:39:49,400 Speaker 2: or indeed where there'll be a whole culture that's not 669 00:39:49,520 --> 00:39:53,439 Speaker 2: using anything and they're depending on stage just switching out 670 00:39:53,480 --> 00:39:56,520 Speaker 2: horses and find you know, realizing that they can't and 671 00:39:56,560 --> 00:40:00,640 Speaker 2: shouldn't just run the horse to death, but they realize, well, 672 00:40:00,640 --> 00:40:02,319 Speaker 2: we just need to switch them out more, and this 673 00:40:02,400 --> 00:40:04,160 Speaker 2: is going to be our approach to making the most 674 00:40:04,160 --> 00:40:06,040 Speaker 2: out of a given hoof and making the hoofs and 675 00:40:06,080 --> 00:40:20,640 Speaker 2: therefore the horse itself lasts longer for us. Now the 676 00:40:20,680 --> 00:40:24,680 Speaker 2: horse shoe itself has a life all its own at 677 00:40:24,680 --> 00:40:28,200 Speaker 2: this point outside of merely nailing it in place in 678 00:40:28,280 --> 00:40:32,400 Speaker 2: the bottom of a horse's foot. As we've touched on 679 00:40:32,440 --> 00:40:35,120 Speaker 2: a bit already, the horseshoe has long been seen as 680 00:40:35,160 --> 00:40:38,399 Speaker 2: a good luck icon in many different cultures, in many 681 00:40:38,400 --> 00:40:41,720 Speaker 2: different times, and it's only kind of interesting to chase 682 00:40:41,800 --> 00:40:45,600 Speaker 2: down like why this is? Like why did people start 683 00:40:46,200 --> 00:40:49,960 Speaker 2: admiring the horseshoe and nailing it up and attracting some 684 00:40:50,120 --> 00:40:51,520 Speaker 2: level of significance to it? 685 00:40:51,960 --> 00:40:55,440 Speaker 3: Very good question. I often find myself wondering about things 686 00:40:55,480 --> 00:40:59,000 Speaker 3: like this, like how did a certain item or image 687 00:40:59,040 --> 00:41:02,880 Speaker 3: come to have good magic or bad magic associated with it. 688 00:41:03,640 --> 00:41:06,799 Speaker 2: Yeah, yeah, so I One of the first places I 689 00:41:06,880 --> 00:41:09,560 Speaker 2: turned to for an answer on this is the book 690 00:41:09,640 --> 00:41:13,920 Speaker 2: Magical House Protection by Brian Hoggard, a former guest on 691 00:41:13,960 --> 00:41:17,120 Speaker 2: the show. I think he was on last October while 692 00:41:17,560 --> 00:41:20,600 Speaker 2: you were on a printal leave. But the book deals 693 00:41:20,640 --> 00:41:22,960 Speaker 2: with various things that people have hidden away in their 694 00:41:23,000 --> 00:41:27,799 Speaker 2: walls and under their floorboards throughout Europe, in the US predominantly, 695 00:41:27,840 --> 00:41:29,560 Speaker 2: but also just throughout the world as a way of 696 00:41:29,600 --> 00:41:32,799 Speaker 2: protecting the house from bad luck, evil spirits, and what 697 00:41:33,000 --> 00:41:37,239 Speaker 2: have you. And Hoggard wrote that, yeah, you find horseshoes 698 00:41:38,040 --> 00:41:41,120 Speaker 2: being associated with good luck throughout the British Isles, Europe, 699 00:41:41,440 --> 00:41:44,400 Speaker 2: the United States, quote, and it would seem the rest 700 00:41:44,400 --> 00:41:47,480 Speaker 2: of the world. He writes that the horseshoe is sometimes 701 00:41:47,520 --> 00:41:51,520 Speaker 2: displayed pointing upward quote, so that the luck doesn't run out, 702 00:41:52,360 --> 00:41:53,960 Speaker 2: which I thought was fun. You know this idea that 703 00:41:53,960 --> 00:41:56,200 Speaker 2: it's like, well, don't have it facing down, because then 704 00:41:56,239 --> 00:41:57,640 Speaker 2: all the luck's going to run out of the ends 705 00:41:57,640 --> 00:42:02,640 Speaker 2: of the horseshoe. While in other areas other traditions, it 706 00:42:02,760 --> 00:42:05,760 Speaker 2: is common to display the horseshoe with the points down. 707 00:42:06,200 --> 00:42:07,960 Speaker 3: I think of it with the points down. I think 708 00:42:08,000 --> 00:42:10,319 Speaker 3: because I think of it hanging up just by a 709 00:42:10,400 --> 00:42:11,320 Speaker 3: nail through the middle. 710 00:42:11,640 --> 00:42:13,799 Speaker 2: Yeah, that's the easiest to do, right. If you hang 711 00:42:13,840 --> 00:42:16,160 Speaker 2: it the other way, you've it's a little more complicated 712 00:42:16,680 --> 00:42:18,359 Speaker 2: or well, I guess it depends. I mean you cause 713 00:42:19,360 --> 00:42:21,120 Speaker 2: the thing about the horseshoe I guess too, is it 714 00:42:21,160 --> 00:42:24,920 Speaker 2: is made to be nailed in place, and therefore it 715 00:42:24,960 --> 00:42:27,400 Speaker 2: can be nailed in its intended place, the bottom of 716 00:42:27,400 --> 00:42:30,160 Speaker 2: a horse's hoof, or it can be nailed in place 717 00:42:30,320 --> 00:42:33,000 Speaker 2: on a barn wall or above your door or what 718 00:42:33,120 --> 00:42:36,480 Speaker 2: have you. Anyway, Haggard highlights two main reasons for the 719 00:42:36,480 --> 00:42:40,120 Speaker 2: horseshoes perceived power. One, and it's certainly a big one, 720 00:42:40,239 --> 00:42:44,040 Speaker 2: is the closer relationship between humans and their horses. You know, 721 00:42:44,120 --> 00:42:48,320 Speaker 2: these are animals that were highly important to the people 722 00:42:48,560 --> 00:42:52,360 Speaker 2: who owned them and or used them. They were animals 723 00:42:52,400 --> 00:42:55,560 Speaker 2: that we ultimately cared about, and we also had various, 724 00:42:56,640 --> 00:42:59,799 Speaker 2: you know, supernatural traditions concerning them. And if not you're 725 00:43:00,320 --> 00:43:02,799 Speaker 2: mundane horses, you have these ideas of mythic horses and 726 00:43:02,840 --> 00:43:05,800 Speaker 2: so forth. And this is something that also influenced the 727 00:43:05,920 --> 00:43:09,879 Speaker 2: use of horse skulls and things like that in other traditions. 728 00:43:10,960 --> 00:43:13,279 Speaker 2: The other key fact that he highlights is that these 729 00:43:13,280 --> 00:43:16,200 Speaker 2: are made of iron, and iron was thought to provide 730 00:43:16,239 --> 00:43:21,080 Speaker 2: protection against quote, witchcraft and the fairy folk. Yes, and 731 00:43:21,360 --> 00:43:24,280 Speaker 2: as Hoggard chronicles in that book, iron horseshoes and iron 732 00:43:24,360 --> 00:43:28,000 Speaker 2: nails were often used in these household productive magics, hidden 733 00:43:28,000 --> 00:43:31,120 Speaker 2: in walls and so forth. I also looked at this 734 00:43:31,200 --> 00:43:33,640 Speaker 2: was an older paper, but I thought it highlighted some 735 00:43:34,040 --> 00:43:37,120 Speaker 2: interesting concepts. This is an eighteen ninety six paper by 736 00:43:37,239 --> 00:43:40,000 Speaker 2: Robert M. Lawrence published in the Journal of American Folklore 737 00:43:40,040 --> 00:43:43,879 Speaker 2: titled The Folklore of the Horseshoe, and Lawrence points out 738 00:43:43,880 --> 00:43:46,799 Speaker 2: that the horseshoe, though shaped the way it's shaped for 739 00:43:46,840 --> 00:43:51,000 Speaker 2: practical reasons, obviously it would have essentially stood in or 740 00:43:51,040 --> 00:43:55,360 Speaker 2: resembled pre existing and potent symbols in different traditions and 741 00:43:55,400 --> 00:43:58,279 Speaker 2: in different cultures. And he highlights some of the key 742 00:43:58,320 --> 00:44:02,200 Speaker 2: ones here. So sure the horseshoe just a standard horseshoe, 743 00:44:02,880 --> 00:44:05,360 Speaker 2: and then think about these. The first one he mentions 744 00:44:05,520 --> 00:44:08,239 Speaker 2: is the idea of a of an arch, just a 745 00:44:08,280 --> 00:44:11,359 Speaker 2: protective arch, something that would be even in an age 746 00:44:11,400 --> 00:44:15,160 Speaker 2: before horseshoes positioned above a doorway or you know, on 747 00:44:15,200 --> 00:44:18,160 Speaker 2: a threshold. I believe he highlights the I want to 748 00:44:18,160 --> 00:44:22,560 Speaker 2: say a Scottish tradition of having an arch shaped from 749 00:44:23,040 --> 00:44:26,000 Speaker 2: from just the branch of a tree would sometimes be 750 00:44:26,120 --> 00:44:26,640 Speaker 2: used like this. 751 00:44:27,320 --> 00:44:29,359 Speaker 3: Well, this may be saying the same thing as saying 752 00:44:29,400 --> 00:44:31,239 Speaker 3: that it sort of resembles an arch, but it also 753 00:44:31,280 --> 00:44:33,520 Speaker 3: sort of resembles a doorway, which is like an arch 754 00:44:33,920 --> 00:44:36,600 Speaker 3: and good luck. Symbols of various kinds are often put 755 00:44:36,640 --> 00:44:37,960 Speaker 3: on or around a doorway. 756 00:44:38,560 --> 00:44:41,000 Speaker 2: Yeah, yeah, I think that's that's a pretty solid one. 757 00:44:41,360 --> 00:44:43,759 Speaker 2: The next one he brings up is that a horseshoe 758 00:44:43,800 --> 00:44:46,919 Speaker 2: is also reminiscent of a serpent, and therefore it could 759 00:44:47,000 --> 00:44:51,920 Speaker 2: tie into various traditions and it involve the use of 760 00:44:51,960 --> 00:44:54,560 Speaker 2: some sort of a serpent symbol, be that a serpent. 761 00:44:54,600 --> 00:44:56,800 Speaker 2: That's you know, I guess it depends what your snack 762 00:44:56,920 --> 00:44:58,880 Speaker 2: is doing. It may be it may be straight, it 763 00:44:58,920 --> 00:45:01,120 Speaker 2: may be coiled up, it may eating its own tail. 764 00:45:01,200 --> 00:45:03,080 Speaker 2: I mean, there's so many different ways the snake has 765 00:45:03,120 --> 00:45:08,480 Speaker 2: been utilized in different iconography over the ages, but this 766 00:45:08,520 --> 00:45:11,279 Speaker 2: one seems sensible. The idea of like the horseshoe as 767 00:45:11,280 --> 00:45:16,200 Speaker 2: a serpent. Another big one the horseshoe is the crescent moon. Now, 768 00:45:16,239 --> 00:45:18,799 Speaker 2: the next one is one that he writes that he 769 00:45:18,800 --> 00:45:21,040 Speaker 2: thinks the evidence is mediocre for this, and he's kind 770 00:45:21,040 --> 00:45:23,239 Speaker 2: of begrudgingly mentioned that. He's like, I'm gonna mention it, 771 00:45:23,239 --> 00:45:26,799 Speaker 2: but I don't like it. And that's the horseshoe could 772 00:45:26,800 --> 00:45:30,960 Speaker 2: also stand in for various ophallic imagery. So the horseshoe 773 00:45:31,000 --> 00:45:32,120 Speaker 2: as thallus. 774 00:45:32,520 --> 00:45:36,200 Speaker 3: Huh, I need to have the case made for that. 775 00:45:36,600 --> 00:45:38,520 Speaker 3: It's not evident to me. 776 00:45:39,440 --> 00:45:41,880 Speaker 2: Yeah. I looked around for more sources on this to 777 00:45:41,880 --> 00:45:43,840 Speaker 2: see if there was anybody advocating for this, and I 778 00:45:43,840 --> 00:45:46,400 Speaker 2: didn't find anything. Maybe it's out there and I just 779 00:45:46,400 --> 00:45:49,000 Speaker 2: couldn't find it. I did see some images of some 780 00:45:49,160 --> 00:45:55,120 Speaker 2: Roman phallic icons and charms that maybe kind of remind 781 00:45:55,200 --> 00:45:57,160 Speaker 2: like I could maybe see it, like there's more than 782 00:45:57,200 --> 00:46:01,400 Speaker 2: one way to create a phallic symbol, and some of 783 00:46:01,400 --> 00:46:04,359 Speaker 2: them are I guess, more horseshoe like than others. But 784 00:46:04,640 --> 00:46:07,680 Speaker 2: still I think maybe Lawrence is right and saying that 785 00:46:07,719 --> 00:46:11,279 Speaker 2: maybe there's not as much sense behind this. This one 786 00:46:11,320 --> 00:46:15,239 Speaker 2: I thought was interesting. The prong shape of the horseshoe 787 00:46:15,440 --> 00:46:17,719 Speaker 2: has a deterrent to evil spirits or as a kind 788 00:46:17,760 --> 00:46:21,520 Speaker 2: of trap. So the idea that the horseshoe is either 789 00:46:21,560 --> 00:46:23,680 Speaker 2: the thing that's going to kind of like catch the 790 00:46:23,719 --> 00:46:27,000 Speaker 2: limb of an evil spirit, you know, you know, like, oh, 791 00:46:27,280 --> 00:46:30,640 Speaker 2: you put your limb, your arm in there, and now 792 00:46:30,680 --> 00:46:32,799 Speaker 2: you can't get it out, or kind of like the 793 00:46:32,840 --> 00:46:34,840 Speaker 2: prongs of some sort of a poking fork. 794 00:46:35,320 --> 00:46:37,920 Speaker 3: Okay, Yeah, that the horseshoe does have a shape that 795 00:46:37,960 --> 00:46:40,760 Speaker 3: seems to contain Yeah. 796 00:46:40,800 --> 00:46:42,920 Speaker 2: And this this lined up with a lot of what 797 00:46:43,239 --> 00:46:47,040 Speaker 2: Hoggard wrote about concerning witch bottles. Witch bottles would often 798 00:46:47,040 --> 00:46:49,320 Speaker 2: have a bunch of nails in them, and the idea 799 00:46:49,360 --> 00:46:51,840 Speaker 2: that like, here's this evil spirit coming into your house 800 00:46:51,880 --> 00:46:54,200 Speaker 2: and then it smells some of your hair that's in 801 00:46:54,239 --> 00:46:57,640 Speaker 2: this bottle that's buried under the floorboards. Oh, it went 802 00:46:57,640 --> 00:47:00,359 Speaker 2: into that bottle after that hair smell, and now found 803 00:47:00,360 --> 00:47:02,920 Speaker 2: a whole bunch of nails. Good luck getting out of 804 00:47:02,960 --> 00:47:03,560 Speaker 2: their spirit. 805 00:47:03,840 --> 00:47:05,520 Speaker 3: Iron nails maybe. 806 00:47:05,320 --> 00:47:07,840 Speaker 2: Yeah, yeah, yeah, I believe they would have been in 807 00:47:07,840 --> 00:47:10,480 Speaker 2: most of these cases. Now. Lawrence also points to the 808 00:47:10,520 --> 00:47:13,240 Speaker 2: sacred nature of the horse and the virtues of iron, 809 00:47:13,360 --> 00:47:16,960 Speaker 2: as Hoggart did. He points to examples from various cultures 810 00:47:16,960 --> 00:47:21,920 Speaker 2: and traditions, including the ancient Romans, Arabic traditions, Chinese, and 811 00:47:21,960 --> 00:47:24,480 Speaker 2: Scottish traditions. So again, it's one of these things when 812 00:47:24,520 --> 00:47:28,200 Speaker 2: you start, it's just it's spread all over. Some other 813 00:47:28,239 --> 00:47:30,839 Speaker 2: ideas that he mentions include the horseshoe is a thing 814 00:47:31,000 --> 00:47:37,920 Speaker 2: that captures traps or transmits bad luck. The position is 815 00:47:37,960 --> 00:47:40,720 Speaker 2: sometimes important here, and like it could be a situation 816 00:47:40,760 --> 00:47:43,160 Speaker 2: where it's like, Okay, here's the horseshoe. You got all 817 00:47:43,200 --> 00:47:45,440 Speaker 2: your bad luck in that. Now leave it on the 818 00:47:45,480 --> 00:47:48,800 Speaker 2: ground and see if someone picks it up and catches 819 00:47:48,840 --> 00:47:51,200 Speaker 2: all that bad luck you just put into it. Then 820 00:47:51,239 --> 00:47:55,000 Speaker 2: there's an idea of numerology coming into it, particularly concerning 821 00:47:55,400 --> 00:47:58,240 Speaker 2: the number of nails in a horseshoe versus the number 822 00:47:58,280 --> 00:48:03,520 Speaker 2: of nail holes. He writes, quote, in Northumberland, the holes 823 00:48:03,840 --> 00:48:07,760 Speaker 2: free of nails are counted as these indicate, presumably in years, 824 00:48:07,960 --> 00:48:10,480 Speaker 2: how soon the finder of the shoe may expect to 825 00:48:10,520 --> 00:48:12,960 Speaker 2: be married. And I guess in this case they're like, 826 00:48:13,000 --> 00:48:14,720 Speaker 2: you know, you're out in the field, you find a horseshoe. 827 00:48:14,719 --> 00:48:16,799 Speaker 2: It's like, oh, I found a horseshoe, let's find out 828 00:48:16,840 --> 00:48:20,760 Speaker 2: how long I'm going to be single. Which and again, 829 00:48:20,960 --> 00:48:23,120 Speaker 2: you know we're not familiar with this tradition, and we 830 00:48:23,120 --> 00:48:24,360 Speaker 2: can kind of snicker at it. But I guess there 831 00:48:24,360 --> 00:48:25,799 Speaker 2: are a lot of things like this. I mean it's 832 00:48:25,880 --> 00:48:29,399 Speaker 2: kind of on a very very like slender level. It's 833 00:48:29,400 --> 00:48:31,399 Speaker 2: almost like, you know, not stepping on a crack, right, 834 00:48:31,520 --> 00:48:34,360 Speaker 2: you know, like we know that's not there's not accurate, 835 00:48:34,440 --> 00:48:36,400 Speaker 2: but we can't help but think about it when we 836 00:48:36,480 --> 00:48:38,759 Speaker 2: do it. And so I can imagine it could be 837 00:48:38,800 --> 00:48:41,120 Speaker 2: this tradition whereas, oh I found a horseshoe exciting for me, 838 00:48:41,520 --> 00:48:42,920 Speaker 2: Maybe I'm going to take this home and put it 839 00:48:43,000 --> 00:48:45,319 Speaker 2: up over my over my doorway for good luck. But 840 00:48:45,400 --> 00:48:48,959 Speaker 2: also what if it's right? What if I am three 841 00:48:49,040 --> 00:48:51,440 Speaker 2: years from finding my wife that sort of thing. 842 00:48:51,800 --> 00:48:55,280 Speaker 3: Well, also, I mean things like this are done for fun, 843 00:48:55,440 --> 00:48:59,560 Speaker 3: even if people don't necessarily believe it's literally predictive. I mean, 844 00:49:00,200 --> 00:49:01,880 Speaker 3: you know, she loves me, She loves me, not on 845 00:49:02,120 --> 00:49:03,320 Speaker 3: flower pedals and stuff. 846 00:49:03,400 --> 00:49:06,520 Speaker 2: Yeah, catching the flowers at a wedding and so forth. 847 00:49:06,920 --> 00:49:09,320 Speaker 2: The other thing you mentioned is that you could consider 848 00:49:09,760 --> 00:49:14,480 Speaker 2: the horseshoe in its resemblance to a halo. M Okay, yeah, 849 00:49:14,520 --> 00:49:16,799 Speaker 2: so I don't remember that coming up at all in 850 00:49:16,880 --> 00:49:19,440 Speaker 2: our episodes about the Halo. We did a series on 851 00:49:19,440 --> 00:49:21,400 Speaker 2: the Halo, and it was a lot of fun. But 852 00:49:22,200 --> 00:49:23,880 Speaker 2: I guess again, we might just think of it like, 853 00:49:23,960 --> 00:49:28,200 Speaker 2: what are some major icons and symbols within any given 854 00:49:28,320 --> 00:49:32,160 Speaker 2: culture that could then here comes this artifact, this, here 855 00:49:32,160 --> 00:49:35,919 Speaker 2: comes this horseshoe. What does that horseshoe remind us of? Now, 856 00:49:35,960 --> 00:49:40,200 Speaker 2: outside of all these superstitions and so forth and older traditions, 857 00:49:40,239 --> 00:49:42,680 Speaker 2: the emblem of a horseshoe remains I think really potent. 858 00:49:44,040 --> 00:49:47,040 Speaker 2: One example of this that came to mind is the 859 00:49:47,120 --> 00:49:51,359 Speaker 2: various cartoon interpretations of this, as well as how it's 860 00:49:51,400 --> 00:49:55,959 Speaker 2: presented sometimes in science textbooks. The horseshoe magnet has become 861 00:49:55,960 --> 00:49:59,600 Speaker 2: a kind of fixed symbol for magnetism, despite the fact 862 00:49:59,640 --> 00:50:02,680 Speaker 2: that horse shoe magnets are technically obsolete, since like the 863 00:50:02,760 --> 00:50:05,720 Speaker 2: nineteen fifties, you don't you don't need a horseshoe shaped magnet. 864 00:50:06,080 --> 00:50:08,920 Speaker 2: All the magnets on your fridge are likely not horseshoe shaped. 865 00:50:09,280 --> 00:50:12,719 Speaker 3: I was thinking about the horseshoe magnet, and especially when 866 00:50:12,800 --> 00:50:16,399 Speaker 3: you were talking about the various magical powers associated with them, 867 00:50:16,400 --> 00:50:19,359 Speaker 3: because of the way horseshoe magnets are represented in cartoons 868 00:50:19,840 --> 00:50:23,120 Speaker 3: as like emitting beams of magic power or with like 869 00:50:23,280 --> 00:50:27,400 Speaker 3: zigzagging lightning of magnetic I don't know what, you know, 870 00:50:27,960 --> 00:50:30,120 Speaker 3: the like zappiness coming out of them. 871 00:50:30,560 --> 00:50:32,719 Speaker 2: Yeah, yeah, I mean it might be a scenario where 872 00:50:32,719 --> 00:50:34,759 Speaker 2: you stopped to think and maybe you're like, hey, do 873 00:50:34,840 --> 00:50:38,200 Speaker 2: I know how magnets work? And then instantly you're struck 874 00:50:38,239 --> 00:50:41,200 Speaker 2: with that cartoon image or that or that little icon 875 00:50:41,239 --> 00:50:43,520 Speaker 2: from your science textbook growing up, where oh yeah, there 876 00:50:43,600 --> 00:50:46,600 Speaker 2: is horseshoe lightning bolts. Now I got it, Now I 877 00:50:46,600 --> 00:50:50,239 Speaker 2: can move on. Now. Another concept to me that some 878 00:50:50,280 --> 00:50:53,160 Speaker 2: people may be thinking of. There's also this horseshoe theory 879 00:50:53,160 --> 00:50:57,560 Speaker 2: of politics, which I'm to understand. I don't. I didn't 880 00:50:57,560 --> 00:50:59,640 Speaker 2: know a lot about it previously, but it's my understanding. 881 00:50:59,680 --> 00:51:02,319 Speaker 2: It's all so it's not something that's really that much 882 00:51:02,320 --> 00:51:05,120 Speaker 2: of a thing within actual political science, but you sometimes 883 00:51:05,120 --> 00:51:09,240 Speaker 2: see it in a lot of popular discourse about people's 884 00:51:09,280 --> 00:51:14,600 Speaker 2: political leanings and their ideologies. This idea that instead of 885 00:51:14,640 --> 00:51:18,800 Speaker 2: it being like a sliding linear scale between on one 886 00:51:19,160 --> 00:51:22,279 Speaker 2: on one end, like leftist extremism and on the other 887 00:51:22,400 --> 00:51:24,680 Speaker 2: end right wing extremism, and then in the middle, you know, 888 00:51:24,800 --> 00:51:28,080 Speaker 2: just just you know, middle of the road, you know, 889 00:51:28,239 --> 00:51:31,600 Speaker 2: neutrality and so forth, then instead of it being shaped 890 00:51:31,600 --> 00:51:33,719 Speaker 2: like that, we should really curve it, and then it's 891 00:51:33,760 --> 00:51:36,000 Speaker 2: more of a horseshoe, and that by virtue of this 892 00:51:36,040 --> 00:51:39,720 Speaker 2: horseshoe shape, it's illustrated that the extremes of either side 893 00:51:39,760 --> 00:51:42,719 Speaker 2: are actually closer than you might think. And this is 894 00:51:42,760 --> 00:51:45,920 Speaker 2: generally generally it's employed to talk about like either like 895 00:51:46,120 --> 00:51:50,399 Speaker 2: an overarching theme, like perhaps that in the extremes there's 896 00:51:50,440 --> 00:51:53,600 Speaker 2: more of a draw towards like a strong leader type 897 00:51:53,680 --> 00:51:58,800 Speaker 2: or totalitarianism or something, or that you might find particular sentiments, 898 00:51:58,800 --> 00:52:01,600 Speaker 2: say like an at anti vac scene sentiment in both 899 00:52:01,640 --> 00:52:04,520 Speaker 2: the far left and the far right, despite these groups 900 00:52:04,520 --> 00:52:07,200 Speaker 2: having little else in common in terms of their ideology. 901 00:52:07,760 --> 00:52:11,200 Speaker 3: Yeah, I've heard people using this analogy in different ways. 902 00:52:11,239 --> 00:52:15,440 Speaker 3: I mean, in I think, in one sense it is 903 00:52:15,480 --> 00:52:19,239 Speaker 3: often used to mean that people think that at the 904 00:52:19,280 --> 00:52:22,560 Speaker 3: far extremes of the political spectrum people actually come to 905 00:52:22,760 --> 00:52:26,000 Speaker 3: share some political ideas. And then I think the other 906 00:52:26,080 --> 00:52:28,400 Speaker 3: ideas that is that at the furthest extremes of the 907 00:52:28,400 --> 00:52:32,600 Speaker 3: political spectrum, people have more i don't know, sort of 908 00:52:32,960 --> 00:52:38,200 Speaker 3: personality based or epistemic things in common apart from political positions. 909 00:52:39,120 --> 00:52:42,319 Speaker 3: And I'm not sure which version of the of the 910 00:52:42,320 --> 00:52:46,040 Speaker 3: model people are really talking about. When they invoke it often. 911 00:52:46,000 --> 00:52:48,640 Speaker 2: Yeah, and I do. It kind of comes back comes 912 00:52:48,719 --> 00:52:51,399 Speaker 2: back to our discussion earlier though about like how do we, 913 00:52:51,480 --> 00:52:54,440 Speaker 2: you know, interpreting data and thinking about like the underlying 914 00:52:54,440 --> 00:52:58,320 Speaker 2: truth of a given situation or a mystery like obviously 915 00:52:58,360 --> 00:53:01,239 Speaker 2: the way people think about the world from ideologies and 916 00:53:01,360 --> 00:53:03,680 Speaker 2: their political viewpoints. I mean, there's a lot of complexity 917 00:53:03,719 --> 00:53:07,000 Speaker 2: going on here, and that complexity can be overwhelming. I mean, 918 00:53:07,040 --> 00:53:09,880 Speaker 2: as we try to make sense of the world's around us, 919 00:53:09,920 --> 00:53:13,160 Speaker 2: the larger world and perhaps even the closer world of 920 00:53:12,239 --> 00:53:16,640 Speaker 2: our friend circles and our families and so forth, and 921 00:53:16,719 --> 00:53:19,319 Speaker 2: it might be tempting to say, but hey, look at 922 00:53:19,320 --> 00:53:22,759 Speaker 2: this horseshoe, Look at this, I think this explains it all. 923 00:53:23,120 --> 00:53:25,680 Speaker 2: You know, it provides maybe a simple model that may 924 00:53:26,320 --> 00:53:30,120 Speaker 2: I mean, maybe it provides some insight, but also a 925 00:53:30,239 --> 00:53:32,239 Speaker 2: level of insight that at least you can sort of 926 00:53:32,719 --> 00:53:34,440 Speaker 2: nod your head at and think like, okay, well this 927 00:53:34,600 --> 00:53:36,840 Speaker 2: kind of lines up with some of the things I'm observing. 928 00:53:37,160 --> 00:53:41,400 Speaker 3: Well, yeah, I think Another twist, for example, is whether 929 00:53:41,520 --> 00:53:44,520 Speaker 3: or not it is useful to think about political beliefs 930 00:53:44,560 --> 00:53:48,800 Speaker 3: as a spectrum at all, meaning that they extend along 931 00:53:48,880 --> 00:53:54,960 Speaker 3: a single dimension or whether it's more useful to decompose 932 00:53:55,080 --> 00:54:00,960 Speaker 3: political beliefs into a number of different types of preferences 933 00:54:01,120 --> 00:54:07,120 Speaker 3: and personality traits. And then in a say, a representative 934 00:54:07,120 --> 00:54:11,120 Speaker 3: democracy with two major parties we represent, we discover that 935 00:54:12,360 --> 00:54:16,840 Speaker 3: political behavior manifests in varying degrees of like or dislike 936 00:54:16,960 --> 00:54:20,040 Speaker 3: for those main two parties. But you know that that 937 00:54:20,080 --> 00:54:24,759 Speaker 3: doesn't fully explain people's the depths of people's beliefs and preferences. 938 00:54:25,400 --> 00:54:29,080 Speaker 2: Yeah, though in isolation it can at least seem to 939 00:54:29,120 --> 00:54:31,480 Speaker 2: make some sense. I had a case of this over 940 00:54:31,480 --> 00:54:33,160 Speaker 2: the weekend. I was in a I was in a 941 00:54:33,160 --> 00:54:35,400 Speaker 2: city that has a lot of crystal stores, so I 942 00:54:35,440 --> 00:54:38,840 Speaker 2: wasn't necessarily out to venture into a crystal store, but 943 00:54:39,200 --> 00:54:41,400 Speaker 2: by virtue of where I was, I just was going 944 00:54:41,440 --> 00:54:44,520 Speaker 2: to wind up in one eventually, and I was looking 945 00:54:44,560 --> 00:54:46,880 Speaker 2: looking around at them. Crystals are beautiful, you know, I 946 00:54:47,600 --> 00:54:49,799 Speaker 2: think they can. They can. They're nice to look at, 947 00:54:49,840 --> 00:54:51,880 Speaker 2: and maybe they're a nice focus sometimes to take you 948 00:54:51,920 --> 00:54:53,200 Speaker 2: out of the past in the future and put you 949 00:54:53,200 --> 00:54:56,280 Speaker 2: into the present. But they have all these little notes 950 00:54:56,280 --> 00:54:58,200 Speaker 2: on them about what they're good for and what focus 951 00:54:58,239 --> 00:55:01,000 Speaker 2: in the crystal will allegedly do for were you, and 952 00:55:01,040 --> 00:55:04,280 Speaker 2: on one table I found one that it was promised, 953 00:55:04,320 --> 00:55:07,680 Speaker 2: would help me connect with quote Christ consciousness, and on 954 00:55:07,760 --> 00:55:12,000 Speaker 2: the other it would help me communicate with extraterrestrials. And 955 00:55:12,040 --> 00:55:14,840 Speaker 2: so generally speaking, I don't know. I would expect that 956 00:55:14,880 --> 00:55:19,640 Speaker 2: people looking to connect with either would have rather different 957 00:55:19,640 --> 00:55:22,320 Speaker 2: world views, you know, the person with the Christ crystal 958 00:55:22,360 --> 00:55:24,799 Speaker 2: and the person with the extraterrestrial crystal, Like maybe they 959 00:55:24,840 --> 00:55:28,399 Speaker 2: want different things out of life. But also they may 960 00:55:28,440 --> 00:55:31,840 Speaker 2: have both wandered into this crystal store, which makes me 961 00:55:31,880 --> 00:55:33,600 Speaker 2: think that think of the you know, the ends of 962 00:55:33,680 --> 00:55:37,359 Speaker 2: the of the horseshoe, you know, arching towards each other. 963 00:55:37,960 --> 00:55:40,080 Speaker 3: Every crystal store I go in, I ask for their 964 00:55:40,200 --> 00:55:44,800 Speaker 3: Nixon consciousness, Christal, what will help me communicate with Nixon? 965 00:55:45,880 --> 00:55:47,120 Speaker 3: He's out there somewhere. 966 00:55:47,360 --> 00:55:49,000 Speaker 2: Oh man, there's got to be a crystal There's got 967 00:55:49,000 --> 00:55:52,560 Speaker 2: to be one that will do it. Unrelated to Nixon, though, 968 00:55:52,800 --> 00:55:54,920 Speaker 2: in discussing this, I am also thinking I don't think 969 00:55:54,960 --> 00:55:58,600 Speaker 2: Lawrence mentioned horns or antlers, but this would seem at 970 00:55:58,719 --> 00:56:01,239 Speaker 2: least just you know, off the the top of my head, 971 00:56:01,280 --> 00:56:03,840 Speaker 2: this would seem to be like a potent symbol to 972 00:56:03,960 --> 00:56:07,200 Speaker 2: jump to. We're interpreting like how people connected with this 973 00:56:07,280 --> 00:56:11,680 Speaker 2: horseshoe with this, you know, for all intensive purposes, this 974 00:56:11,840 --> 00:56:17,640 Speaker 2: new artifact that lines up with various symbols of potents, 975 00:56:17,719 --> 00:56:21,520 Speaker 2: like the horns and antlers have long been and still 976 00:56:21,560 --> 00:56:24,400 Speaker 2: are things of symbolic power. 977 00:56:24,520 --> 00:56:27,360 Speaker 3: In a quite literal sense in their biological context, but 978 00:56:27,400 --> 00:56:29,320 Speaker 3: then in a metaphorical sense to humans. 979 00:56:29,400 --> 00:56:32,640 Speaker 2: Yeah, yeah, all right, Well, on that note, we're gonna 980 00:56:32,640 --> 00:56:34,440 Speaker 2: ahead and close this episode out, but we'd love to 981 00:56:34,440 --> 00:56:36,320 Speaker 2: hear from everyone out there if you have thoughts about 982 00:56:36,960 --> 00:56:41,759 Speaker 2: the horse hoof the horseshoe, interpretations of the horseshoe, the 983 00:56:41,880 --> 00:56:45,279 Speaker 2: use of hoof boots, be they equine hoof boots or 984 00:56:45,360 --> 00:56:48,520 Speaker 2: human hoof boots. Everything is fair game, right in, we'd 985 00:56:48,560 --> 00:56:50,640 Speaker 2: love to hear from you. In the meantime, you can 986 00:56:50,640 --> 00:56:52,839 Speaker 2: find all of our core episodes, so Stuff to Blow 987 00:56:52,880 --> 00:56:55,120 Speaker 2: your Mind on Tuesdays and Thursdays and the Stuff to 988 00:56:55,120 --> 00:56:57,719 Speaker 2: Blow your Mind podcast feed.
