1 00:00:06,240 --> 00:00:08,480 Speaker 1: Hey, you welcome to Stuff to Blow Your Mind. My 2 00:00:08,600 --> 00:00:09,800 Speaker 1: name is Robert Lamb. 3 00:00:09,880 --> 00:00:12,039 Speaker 2: And I am Joe McCormick, and Rob and I are 4 00:00:12,039 --> 00:00:14,480 Speaker 2: out this week, so we're bringing you an episode from 5 00:00:14,760 --> 00:00:17,600 Speaker 2: the vault. This is sort of part four in our 6 00:00:17,640 --> 00:00:21,119 Speaker 2: series that we started reairing last week about throwing behaviors 7 00:00:21,120 --> 00:00:23,280 Speaker 2: in non human animals. But here we're getting, of course, 8 00:00:23,320 --> 00:00:27,360 Speaker 2: to the emergence of throwing behaviors in humans and human ancestors. 9 00:00:28,040 --> 00:00:30,640 Speaker 2: I hope you enjoy and oh this one originally published 10 00:00:30,680 --> 00:00:36,080 Speaker 2: January twelfth, twenty twenty three. 11 00:00:36,159 --> 00:00:44,159 Speaker 3: Welcome to Stuff to Blow Your Mind, production of iHeartRadio. 12 00:00:46,040 --> 00:00:48,080 Speaker 1: Hey, welcome to Stuff to Blow Your Mind. My name 13 00:00:48,120 --> 00:00:49,000 Speaker 1: is Robert Lamb. 14 00:00:49,320 --> 00:00:52,120 Speaker 2: And I'm Joe McCormick, and we're back with part four 15 00:00:52,479 --> 00:00:56,200 Speaker 2: of our series on throwing behavior. Now, in previous parts 16 00:00:56,200 --> 00:00:59,880 Speaker 2: we focused mainly on non human animals. We've looked at 17 00:01:00,320 --> 00:01:06,640 Speaker 2: alleged throwing behaviors in octopuses, in elephants, in the mongoose. 18 00:01:07,120 --> 00:01:09,920 Speaker 2: We definitely had a digression about dogs with air Bud 19 00:01:10,040 --> 00:01:13,639 Speaker 2: in the previous episode. But also in the previous episode 20 00:01:13,760 --> 00:01:17,480 Speaker 2: we ended up talking about the evolution of the human 21 00:01:17,720 --> 00:01:22,120 Speaker 2: capacity for throwing, which we are particularly apt at Humans 22 00:01:22,319 --> 00:01:25,800 Speaker 2: are very good at throwing, especially compared to our nearest 23 00:01:25,920 --> 00:01:30,080 Speaker 2: primate relatives. So like a chimpanzee maybe on average three 24 00:01:30,160 --> 00:01:32,800 Speaker 2: or four times stronger than a human, But a human, 25 00:01:32,920 --> 00:01:36,560 Speaker 2: even without specialized training, can generally throw a lot more 26 00:01:36,560 --> 00:01:39,200 Speaker 2: forcefully and a lot better than a chimpanzee can. So 27 00:01:39,240 --> 00:01:41,759 Speaker 2: why are we so specialized for throwing? Well, we took 28 00:01:41,760 --> 00:01:46,160 Speaker 2: a look at some evolutionary hypotheses about where our capacity 29 00:01:46,200 --> 00:01:49,200 Speaker 2: for throwing comes from. But there was another thing that 30 00:01:49,280 --> 00:01:53,160 Speaker 2: I came across while researching this subject that I did 31 00:01:53,160 --> 00:01:56,280 Speaker 2: not get into in the previous episode, and I wanted 32 00:01:56,320 --> 00:01:57,760 Speaker 2: to come back to it here because I found it 33 00:01:57,800 --> 00:02:02,080 Speaker 2: really interesting. And this is the idea of what if 34 00:02:02,120 --> 00:02:07,120 Speaker 2: the evolution of throwing was somehow a necessary precursor for 35 00:02:07,200 --> 00:02:12,320 Speaker 2: the evolution of probably the most distinctly human trait language, 36 00:02:13,880 --> 00:02:16,400 Speaker 2: So not just that humans are good at throwing and 37 00:02:16,639 --> 00:02:20,440 Speaker 2: good at language, but that there is actually a neurobiological 38 00:02:20,560 --> 00:02:24,799 Speaker 2: link between the two one comes from the other. So 39 00:02:25,040 --> 00:02:29,120 Speaker 2: to look at this question, I wanted to refer to 40 00:02:29,160 --> 00:02:32,560 Speaker 2: a paper by William D. Hopkins, Jamie L. Russell, and 41 00:02:32,639 --> 00:02:36,600 Speaker 2: Jennifer A. Schaeffer published in Philosophical Transactions of the Royal 42 00:02:36,639 --> 00:02:41,200 Speaker 2: Society b Biological Sciences, published in twenty twelve, called the 43 00:02:41,320 --> 00:02:47,000 Speaker 2: Neural and Cognitive Correlates of Aimed Throwing in Chimpanzees a magnetic, resonance, image, 44 00:02:47,040 --> 00:02:50,720 Speaker 2: and behavioral study on a unique form of social tool use. 45 00:02:52,200 --> 00:02:55,160 Speaker 2: So to begin, they cover some of the same ground 46 00:02:55,200 --> 00:02:59,680 Speaker 2: we did in the previous episode. You know how unusual 47 00:02:59,760 --> 00:03:02,960 Speaker 2: he when throwing behavior is in a way, and despite 48 00:03:02,960 --> 00:03:05,720 Speaker 2: all the interesting examples we've discussed in these episodes of 49 00:03:05,760 --> 00:03:09,160 Speaker 2: animals throwing things for various reasons, whether trained by humans 50 00:03:09,240 --> 00:03:11,960 Speaker 2: or just doing it as part of their natural instinctual behaviors, 51 00:03:12,800 --> 00:03:17,120 Speaker 2: the authors here argue that in general, throwing remains unsystematic, 52 00:03:17,320 --> 00:03:19,320 Speaker 2: in their words, in other animals, And I think this 53 00:03:19,360 --> 00:03:24,440 Speaker 2: is fair. No other animal practices the kind of generalized, 54 00:03:24,639 --> 00:03:28,720 Speaker 2: skillful habitual throwing that we do, certainly not without training 55 00:03:28,760 --> 00:03:29,440 Speaker 2: by humans. 56 00:03:30,200 --> 00:03:31,920 Speaker 1: Yeah, as we discussed in the previous episode, it goes 57 00:03:31,960 --> 00:03:36,120 Speaker 1: way back in human behavior, and it's something that even today, 58 00:03:36,200 --> 00:03:38,839 Speaker 1: with all our other tools and ways of doing things 59 00:03:38,920 --> 00:03:44,120 Speaker 1: at a distance, we still engage in throwing. I think 60 00:03:44,160 --> 00:03:46,360 Speaker 1: in the very first episode we discussed that sort of 61 00:03:47,560 --> 00:03:51,600 Speaker 1: at least in my case, this strange pull to need 62 00:03:51,640 --> 00:03:54,520 Speaker 1: to throw a ball with my son when he was younger, 63 00:03:55,520 --> 00:03:59,240 Speaker 1: even though we're not a baseball or softball family. But 64 00:03:59,320 --> 00:04:00,720 Speaker 1: it was just kind of the thing that I guess 65 00:04:00,800 --> 00:04:03,680 Speaker 1: was like nostalgic in the culture, but also very satisfying 66 00:04:03,720 --> 00:04:06,200 Speaker 1: to do and something that even if you're not very 67 00:04:06,200 --> 00:04:08,720 Speaker 1: practiced at you can do with some or at least 68 00:04:08,720 --> 00:04:11,040 Speaker 1: I found that I could do with some degree of precision, 69 00:04:12,560 --> 00:04:15,640 Speaker 1: despite being very rusty at the whole softball baseball thing. 70 00:04:16,200 --> 00:04:19,120 Speaker 2: I totally sympathize with you there. I mean, I think 71 00:04:19,200 --> 00:04:21,719 Speaker 2: neither of us are really sports guys. I don't really 72 00:04:21,720 --> 00:04:23,920 Speaker 2: want rules, I don't really want teams, but I do 73 00:04:24,000 --> 00:04:29,200 Speaker 2: want ball or frisbee. Frisbee just as good in my opinion. 74 00:04:29,839 --> 00:04:32,240 Speaker 1: Yeah, And I mean there's also there's a lot more 75 00:04:32,279 --> 00:04:35,080 Speaker 1: throwing that goes on too, Like how often do we 76 00:04:35,080 --> 00:04:37,880 Speaker 1: find ourselves across the room from someone We request something 77 00:04:38,200 --> 00:04:40,120 Speaker 1: and they give it a tok, they throw it to us, 78 00:04:40,400 --> 00:04:41,680 Speaker 1: and you want to be able to catch it for 79 00:04:41,760 --> 00:04:44,920 Speaker 1: various reasons. And then that's without even getting into the 80 00:04:45,000 --> 00:04:47,159 Speaker 1: various sports that even if we don't engage in, we 81 00:04:47,240 --> 00:04:51,560 Speaker 1: may watch and the throwing of balls is often an 82 00:04:51,640 --> 00:04:54,320 Speaker 1: essential part, or at least one aspect of a given 83 00:04:54,320 --> 00:04:55,520 Speaker 1: sport right. 84 00:04:56,200 --> 00:04:59,520 Speaker 2: But of course, apart from these recreational concerns, you know, 85 00:04:59,640 --> 00:05:03,839 Speaker 2: throwing has been crucial to the survival of our ancestors. 86 00:05:03,880 --> 00:05:06,200 Speaker 2: That seems pretty clear. And in the last episode we 87 00:05:06,200 --> 00:05:10,560 Speaker 2: talked about arguments from evolutionary anthropology that throwing was positively 88 00:05:10,640 --> 00:05:14,120 Speaker 2: selected for in human ancestors, and the bodies of hominin 89 00:05:14,200 --> 00:05:18,760 Speaker 2: species like Homo erectus show anatomical changes that seem to 90 00:05:18,800 --> 00:05:24,520 Speaker 2: favor forceful overhand throwing. I remember those changes. They're changes 91 00:05:24,560 --> 00:05:27,000 Speaker 2: in the shoulder and the waist and the upper arm, 92 00:05:27,120 --> 00:05:30,440 Speaker 2: all of which combined to allow for a more substantial 93 00:05:30,600 --> 00:05:33,200 Speaker 2: wind up, sort of a pulling back of tension of 94 00:05:33,680 --> 00:05:38,200 Speaker 2: the biomechanical bowstring to be released rapidly during the throw. 95 00:05:38,839 --> 00:05:41,360 Speaker 2: And we also talked about the argument that these changes 96 00:05:41,400 --> 00:05:44,760 Speaker 2: appear to coincide with evidence of meat becoming a bigger 97 00:05:44,800 --> 00:05:48,200 Speaker 2: part of the diet of these hominins, showing that throwing 98 00:05:49,080 --> 00:05:53,640 Speaker 2: was likely useful for obtaining food, either through power scavenging 99 00:05:53,760 --> 00:05:56,479 Speaker 2: like driving predators away from a kill in order to 100 00:05:56,480 --> 00:05:59,760 Speaker 2: take the meat for yourself, or direct hunting, and either 101 00:05:59,760 --> 00:06:04,159 Speaker 2: way increasing the availability of food energy. Now, one very 102 00:06:04,160 --> 00:06:07,800 Speaker 2: interesting thing about the adaptation for throwing is that it 103 00:06:07,880 --> 00:06:11,960 Speaker 2: implies not only changes in the muscles and the skeletal system. 104 00:06:12,080 --> 00:06:14,000 Speaker 2: Of course, you know, you can see all those changes 105 00:06:14,040 --> 00:06:16,679 Speaker 2: around the scapula and the shoulder blade, changes in the waist, 106 00:06:16,800 --> 00:06:20,520 Speaker 2: the arm, and so forth, But it also implies changes 107 00:06:20,640 --> 00:06:25,720 Speaker 2: in cognition. An animal that can throw objects sourced from 108 00:06:25,800 --> 00:06:30,120 Speaker 2: the environment is showing a specialized way of thinking, and 109 00:06:30,160 --> 00:06:33,359 Speaker 2: not just a specialized way of moving. Now what do 110 00:06:33,400 --> 00:06:36,039 Speaker 2: I mean by this? Well, as one example, the authors 111 00:06:36,120 --> 00:06:40,240 Speaker 2: reference a specific captive chimpanzee who came up in the 112 00:06:40,279 --> 00:06:43,560 Speaker 2: last episode. Robie, remember the story of Santino, the chimpanzee 113 00:06:43,560 --> 00:06:45,880 Speaker 2: who was in a zoo and I believe Sweden was it? 114 00:06:46,440 --> 00:06:46,839 Speaker 1: I believe? 115 00:06:46,880 --> 00:06:51,480 Speaker 2: So, yes, Ip Santino, Yeah, poor Santino. The authors right 116 00:06:51,600 --> 00:06:54,960 Speaker 2: that Santino, who I guess was alive at the time 117 00:06:55,000 --> 00:06:58,400 Speaker 2: this paper was written. Quote hydes rocks out of sight 118 00:06:58,480 --> 00:07:01,200 Speaker 2: of the care staff, waiting to reveal and throw them 119 00:07:01,200 --> 00:07:04,960 Speaker 2: at approaching visitors at the most opportune time. Evidence of 120 00:07:05,080 --> 00:07:08,520 Speaker 2: planning comes from the observation that Santino searches for the 121 00:07:08,640 --> 00:07:12,280 Speaker 2: rocks from a moat inside the enclosure prior to the 122 00:07:12,360 --> 00:07:15,800 Speaker 2: arrival of the care staff and the visitors, and cashes 123 00:07:15,880 --> 00:07:18,360 Speaker 2: the rocks out of sight, only to pull them out 124 00:07:18,400 --> 00:07:22,600 Speaker 2: when the visitors arrive. That is a crafty chimp, and 125 00:07:22,240 --> 00:07:28,480 Speaker 2: that is forethought. Adding to this, the authors throw in 126 00:07:28,520 --> 00:07:32,200 Speaker 2: their own observations of similar pre planning behavior in chimpanzees 127 00:07:32,200 --> 00:07:35,400 Speaker 2: in two other research environments, and they argue that the 128 00:07:35,440 --> 00:07:40,000 Speaker 2: throwing quote, though often agonistic in function and consequence, agonistic 129 00:07:40,040 --> 00:07:45,200 Speaker 2: meaningless confrontational aggressive behavior, is not part of the ape's 130 00:07:45,280 --> 00:07:49,520 Speaker 2: display behavior. Indeed, most instances of aimed throwing that we 131 00:07:49,560 --> 00:07:53,840 Speaker 2: have observed occur without any accompanying display behavior such as 132 00:07:53,840 --> 00:07:58,640 Speaker 2: pilo erection, hooting, and charging, further suggesting an element of 133 00:07:58,720 --> 00:08:02,120 Speaker 2: planning on the part of the individual ape. So I 134 00:08:02,160 --> 00:08:04,480 Speaker 2: think that's interesting too if you understand what they're saying there, 135 00:08:04,640 --> 00:08:09,040 Speaker 2: that there is a sort of standard display behavior algorithm, 136 00:08:09,160 --> 00:08:12,840 Speaker 2: like when an ape is doing an agonistic display when 137 00:08:12,840 --> 00:08:15,960 Speaker 2: trying to be dominant and aggressive and maybe scare you off. 138 00:08:17,080 --> 00:08:19,680 Speaker 2: It includes all of these sub features like the pilo 139 00:08:19,720 --> 00:08:23,560 Speaker 2: erection meaning the bristling of body hair, hair stands on end, hooting, 140 00:08:23,720 --> 00:08:27,200 Speaker 2: charging back and forth, all that stuff. And they say 141 00:08:27,240 --> 00:08:30,080 Speaker 2: that when the apes throw stuff at people, they do 142 00:08:30,160 --> 00:08:33,040 Speaker 2: it without all of these other features of a typical 143 00:08:33,160 --> 00:08:37,000 Speaker 2: instinctual display. Another way that throwing is different from most 144 00:08:37,000 --> 00:08:40,680 Speaker 2: other forms of tool use and apes. The most commonly 145 00:08:40,720 --> 00:08:44,480 Speaker 2: observed types of tool use by wild chimpanzees are all 146 00:08:44,640 --> 00:08:49,600 Speaker 2: things where the tool is used to extract otherwise unreachable food, 147 00:08:49,760 --> 00:08:52,360 Speaker 2: often like from a hole or enclosure of some kind, 148 00:08:52,920 --> 00:08:55,720 Speaker 2: and then is eaten immediately. So examples here would be 149 00:08:55,800 --> 00:08:58,959 Speaker 2: cracking of nuts with stones like nut cracking is an 150 00:08:58,960 --> 00:09:02,320 Speaker 2: example of ape tool use, but also termite fishing with sticks, 151 00:09:02,440 --> 00:09:05,760 Speaker 2: ant dipping, and so forth. All of these give rise 152 00:09:05,800 --> 00:09:10,040 Speaker 2: to an immediate food reward for executing the behavior, meaning 153 00:09:10,360 --> 00:09:15,440 Speaker 2: that these behaviors are subject to regular operant conditioning rules. 154 00:09:16,280 --> 00:09:19,480 Speaker 2: You know, if a behavior leads to an immediate food reward, 155 00:09:19,720 --> 00:09:23,320 Speaker 2: an animal can learn to repeat basically any arbitrary set 156 00:09:23,360 --> 00:09:27,200 Speaker 2: of actions. So you know, chimpanzee gets delicious termites every 157 00:09:27,200 --> 00:09:30,160 Speaker 2: time it. Of course, if it dips for them, that's 158 00:09:30,160 --> 00:09:32,200 Speaker 2: one thing. But maybe if it stands on one foot 159 00:09:32,440 --> 00:09:35,040 Speaker 2: and gets termites every time, it may learn to stand 160 00:09:35,080 --> 00:09:36,520 Speaker 2: on one foot to get the meat. 161 00:09:37,120 --> 00:09:40,920 Speaker 1: Yeah, and we see this reflected and so many experiments 162 00:09:40,960 --> 00:09:44,200 Speaker 1: involving animals over the years. You know, can you get 163 00:09:44,600 --> 00:09:48,320 Speaker 1: an animal to manipulate some sort of technological gadget in 164 00:09:48,440 --> 00:09:50,200 Speaker 1: order to get a food reward. 165 00:09:50,240 --> 00:09:52,320 Speaker 2: Yeah, pressing a button or something that would have no 166 00:09:52,400 --> 00:09:56,720 Speaker 2: relevance in the natural environment. So other tool use behaviors 167 00:09:56,760 --> 00:10:00,839 Speaker 2: could easily be learned and reinforced through this kind of conditioning. 168 00:10:00,920 --> 00:10:04,800 Speaker 2: But throwing, as practiced by apes does not lead to 169 00:10:04,840 --> 00:10:07,720 Speaker 2: an immediate food reward. In fact, it rarely, if ever, 170 00:10:08,280 --> 00:10:12,720 Speaker 2: leads to a food reward at all the author's right quote. 171 00:10:12,880 --> 00:10:15,960 Speaker 2: What appears to be the main reward for throwing is 172 00:10:16,000 --> 00:10:20,040 Speaker 2: the simple ability to control or manipulate the behavior of 173 00:10:20,080 --> 00:10:24,480 Speaker 2: the targeted individual ape or human, which, though you could 174 00:10:24,520 --> 00:10:27,400 Speaker 2: consider it a goal, I mean that is much more 175 00:10:27,559 --> 00:10:31,200 Speaker 2: complicated and ambiguous than a direct food reward. 176 00:10:32,120 --> 00:10:35,439 Speaker 1: Yeah, because it's not like the ape in this scenario 177 00:10:36,120 --> 00:10:39,719 Speaker 1: is throwing the rock, hitting the human, and then by 178 00:10:39,800 --> 00:10:42,160 Speaker 1: hitting the human they drop an apple, right. 179 00:10:42,280 --> 00:10:46,160 Speaker 2: Yeah. Now, from here, the authors go on to discuss 180 00:10:46,200 --> 00:10:49,760 Speaker 2: the underappreciated complexity of throwing. We also talked about this 181 00:10:49,800 --> 00:10:52,520 Speaker 2: at length in the previous episode. But you know, suffice 182 00:10:52,520 --> 00:10:56,240 Speaker 2: to say, force full, precise overhand throwing is an extremely 183 00:10:56,280 --> 00:10:59,960 Speaker 2: demanding task, not only for the muscles but for the brain, 184 00:11:00,160 --> 00:11:04,360 Speaker 2: requiring split second coordination of perceptual judgments all kinds of things. 185 00:11:04,400 --> 00:11:06,160 Speaker 2: You know, how far away is the target, is it 186 00:11:06,240 --> 00:11:08,880 Speaker 2: moving in what direction? And how fast? What are the 187 00:11:08,880 --> 00:11:12,160 Speaker 2: physical properties of the projectile and so forth. But then 188 00:11:12,200 --> 00:11:16,600 Speaker 2: the other thing is the sequential motor control. To throw 189 00:11:16,920 --> 00:11:21,720 Speaker 2: an object, you have to precisely time a rapid sequence 190 00:11:21,840 --> 00:11:27,800 Speaker 2: of muscular movements, and other authors have previously suggested that 191 00:11:28,000 --> 00:11:33,239 Speaker 2: quote the increased selection for neural synchrony of rapid muscular sequencing. 192 00:11:33,320 --> 00:11:37,880 Speaker 2: Routines associated with actions such as throwing are similar to 193 00:11:38,240 --> 00:11:43,040 Speaker 2: the motor programming demands of language and speech, and therefore 194 00:11:43,120 --> 00:11:50,160 Speaker 2: engage similar neural systems, notably Broca's area. In other words, 195 00:11:50,240 --> 00:11:53,720 Speaker 2: there are similarities between what the brain is doing and 196 00:11:53,760 --> 00:11:56,959 Speaker 2: what parts of the brain are being used to coordinate 197 00:11:57,000 --> 00:12:02,560 Speaker 2: a throw and to process language and speech. And one 198 00:12:02,559 --> 00:12:04,800 Speaker 2: idea that gets wrapped up in this is the role 199 00:12:04,880 --> 00:12:10,600 Speaker 2: of brain lateralization, segmenting of brain processes to one hemisphere 200 00:12:10,720 --> 00:12:13,600 Speaker 2: or side of the brain or the other. So in 201 00:12:13,640 --> 00:12:16,240 Speaker 2: cultures where throwing behavior has been studied, the authors say 202 00:12:16,280 --> 00:12:18,840 Speaker 2: the majority of people pretty much always prefer to throw 203 00:12:19,040 --> 00:12:22,800 Speaker 2: with the right hand. Studies in chimpanzees also show a 204 00:12:22,840 --> 00:12:26,840 Speaker 2: bias toward right handedness for throwing, and these right hand 205 00:12:26,920 --> 00:12:31,320 Speaker 2: preferences suggest left hemisphere dominance in the brain in these 206 00:12:31,400 --> 00:12:34,760 Speaker 2: majorities of both populations, because when it comes to controlling 207 00:12:34,800 --> 00:12:38,360 Speaker 2: the body's movements, of course, you know, the hemispheres are flipped. Generally, 208 00:12:38,400 --> 00:12:40,800 Speaker 2: the left hemisphere links to the right hand, the right 209 00:12:40,800 --> 00:12:44,880 Speaker 2: hemisphere to the left, and so forth. Some researchers have 210 00:12:45,000 --> 00:12:48,320 Speaker 2: pointed this out in the context of the fact that 211 00:12:48,360 --> 00:12:53,520 Speaker 2: the left hemisphere also contains the brain regions, notably Broca's area, 212 00:12:54,160 --> 00:12:57,400 Speaker 2: that dominate the production of speech. Broker's area is also 213 00:12:57,480 --> 00:13:01,360 Speaker 2: known as the motor speech area, and one researcher who 214 00:13:01,440 --> 00:13:05,280 Speaker 2: has focused on this is the American neurophysiologist William H. Calvin, 215 00:13:05,320 --> 00:13:08,760 Speaker 2: who was actually, I think maybe still is a professor 216 00:13:08,800 --> 00:13:14,280 Speaker 2: at the University of Washington at Seattle, who observing that 217 00:13:14,360 --> 00:13:16,760 Speaker 2: eighty nine percent of people prefer to throw with the 218 00:13:16,880 --> 00:13:21,680 Speaker 2: right arm, Calvin hypothesized that the left hemispher's capacity for 219 00:13:21,840 --> 00:13:26,800 Speaker 2: language may have actually evolved from a pre existing adaptation 220 00:13:27,440 --> 00:13:31,400 Speaker 2: for right handed throwing. He apparently published a book that 221 00:13:31,480 --> 00:13:35,360 Speaker 2: contained this hypothesis. In nineteen eighty three, it was called 222 00:13:35,400 --> 00:13:36,640 Speaker 2: The Throwing Madonna. 223 00:13:37,440 --> 00:13:40,600 Speaker 1: Oh didn't they adapted this into the film a lead 224 00:13:40,640 --> 00:13:41,360 Speaker 1: of their own right? 225 00:13:43,280 --> 00:13:44,080 Speaker 2: Was Madonna in that? 226 00:13:44,600 --> 00:13:45,040 Speaker 1: I believe? 227 00:13:45,080 --> 00:13:45,120 Speaker 3: So? 228 00:13:45,320 --> 00:13:45,520 Speaker 1: Yeah? 229 00:13:45,520 --> 00:13:47,880 Speaker 2: Oh, okay? Was she the picture in the movie? 230 00:13:48,320 --> 00:13:50,960 Speaker 1: Ah? Oh, I don't remember, but I mean surely she 231 00:13:51,040 --> 00:13:52,640 Speaker 1: threw a ball at least once. I mean there's a 232 00:13:52,679 --> 00:13:55,120 Speaker 1: lot of throwing in baseball. 233 00:13:55,400 --> 00:13:57,319 Speaker 2: Yeah, you throw, no matter what position you are. I 234 00:13:57,320 --> 00:13:58,600 Speaker 2: guess the picture throws the most. 235 00:13:58,840 --> 00:14:01,280 Speaker 1: There's no crying in baseball, but there was throwing in baseball. 236 00:14:01,440 --> 00:14:03,280 Speaker 1: There's a lot that much. I remember for the film. 237 00:14:03,760 --> 00:14:06,680 Speaker 2: Okay, so Madonna was definitely throwing, no matter what position 238 00:14:06,760 --> 00:14:10,440 Speaker 2: she played. No, but it unfortunately did not become the 239 00:14:10,440 --> 00:14:12,880 Speaker 2: basis of the movie as far as I know. Instead, 240 00:14:13,040 --> 00:14:15,959 Speaker 2: it was a place where Calvin laid out an interesting 241 00:14:17,240 --> 00:14:21,280 Speaker 2: sort of story, a possible series of developments that could 242 00:14:21,320 --> 00:14:25,800 Speaker 2: have led to the development of language via the stepping 243 00:14:25,840 --> 00:14:30,760 Speaker 2: stone of capacity for throwing. So the story goes like this, 244 00:14:31,760 --> 00:14:36,640 Speaker 2: lateralization evolved for one handed throwing with the right hand, 245 00:14:36,800 --> 00:14:41,680 Speaker 2: specifically so that parents, typically mothers, could cradle an infant 246 00:14:41,840 --> 00:14:45,520 Speaker 2: on their left side and then they'd be free to 247 00:14:45,760 --> 00:14:49,360 Speaker 2: throw with the right hand if they needed to. So, 248 00:14:49,440 --> 00:14:51,800 Speaker 2: I mean, obviously things like this are hard to prove 249 00:14:51,920 --> 00:14:55,080 Speaker 2: for sure, but that is an interesting idea because I 250 00:14:55,160 --> 00:14:59,040 Speaker 2: started thinking about how I recently became a father, and 251 00:14:59,240 --> 00:15:02,840 Speaker 2: without thinking about it at all, I pretty much always 252 00:15:02,880 --> 00:15:05,720 Speaker 2: when I hold my baby, hold her on the left 253 00:15:05,760 --> 00:15:08,640 Speaker 2: side of my torso, and so if she like falls 254 00:15:08,680 --> 00:15:11,560 Speaker 2: asleep against me, her head is going to be on 255 00:15:11,680 --> 00:15:15,320 Speaker 2: the left side of my chest and from my point 256 00:15:15,320 --> 00:15:18,000 Speaker 2: of view, which is also the side where the heartbeat 257 00:15:18,080 --> 00:15:20,880 Speaker 2: is closer. I never planned it that way, that that 258 00:15:21,040 --> 00:15:24,240 Speaker 2: just sort of happened, and I was talking to my 259 00:15:24,320 --> 00:15:27,080 Speaker 2: wife and she said, yeah, most often she's on the 260 00:15:27,120 --> 00:15:29,920 Speaker 2: left side there too, So I don't know that that's 261 00:15:30,000 --> 00:15:32,200 Speaker 2: kind of interesting. I mean, it could be totally unrelated, 262 00:15:32,200 --> 00:15:32,720 Speaker 2: but I don't know. 263 00:15:33,640 --> 00:15:36,360 Speaker 1: Yeah, yeah, yeah, I would always scoop up on the 264 00:15:36,440 --> 00:15:38,720 Speaker 1: left side as well. My son is now I think 265 00:15:38,760 --> 00:15:42,240 Speaker 1: finally too big for me to do that without seriously 266 00:15:42,240 --> 00:15:43,000 Speaker 1: injuring myself. 267 00:15:43,040 --> 00:15:46,040 Speaker 2: But yes, and I guess at a certain point you 268 00:15:46,120 --> 00:15:49,320 Speaker 2: become less desiring of the heartbeat sound that like maybe 269 00:15:49,360 --> 00:15:52,360 Speaker 2: loses some of the power it has over really young infants. 270 00:15:52,920 --> 00:15:55,280 Speaker 1: Yeah, I don't know. I guess it varies from child 271 00:15:55,280 --> 00:15:58,440 Speaker 1: to child, depends on how big they get and at 272 00:15:58,480 --> 00:15:59,920 Speaker 1: what point they want that distance. 273 00:16:10,000 --> 00:16:11,960 Speaker 2: Okay, well, so it's hard to know for sure if 274 00:16:11,960 --> 00:16:13,920 Speaker 2: the need to scoop a child and hold them on 275 00:16:13,960 --> 00:16:15,960 Speaker 2: the left side of the body, close to the heartbeat 276 00:16:16,080 --> 00:16:19,760 Speaker 2: is the real reason driving brain lateralization. I find it 277 00:16:19,840 --> 00:16:23,520 Speaker 2: more compelling than some other hypotheses that seemed to be 278 00:16:24,400 --> 00:16:27,160 Speaker 2: on offer at the time, one that cited I was 279 00:16:27,200 --> 00:16:30,200 Speaker 2: reading a review of this book by Calvin that cited 280 00:16:30,200 --> 00:16:35,120 Speaker 2: a previous hypothesis that the right handedness evolved because men 281 00:16:35,240 --> 00:16:39,160 Speaker 2: in battle I guess prehistoric battle needed to hold a 282 00:16:39,240 --> 00:16:42,320 Speaker 2: shield above their above their heart on the left side. 283 00:16:42,400 --> 00:16:43,720 Speaker 2: I was like, I get out of here. 284 00:16:45,800 --> 00:16:49,680 Speaker 1: This discussion reminds me of a painting, an eighteen eighty 285 00:16:49,720 --> 00:16:51,520 Speaker 1: eight painting that I hadn't thought of in a bit, 286 00:16:52,080 --> 00:16:54,120 Speaker 1: I believe what if The title of this piece is 287 00:16:54,160 --> 00:17:01,680 Speaker 1: Two Mothers by Leon Maxim of Favre. I'm pronouncing that correctly. 288 00:17:01,720 --> 00:17:05,040 Speaker 1: It's f A I v R. But it's a pretty 289 00:17:05,320 --> 00:17:09,600 Speaker 1: stunning piece in which we see this vision of a 290 00:17:10,119 --> 00:17:13,800 Speaker 1: of a prehistoric mother with very modern touches to it. 291 00:17:14,400 --> 00:17:17,080 Speaker 1: But she's standing here in some sort of a you know, 292 00:17:17,119 --> 00:17:21,760 Speaker 1: a hide garment, and she has this heavy looking infant 293 00:17:22,000 --> 00:17:25,480 Speaker 1: in her left arm, and then there's another child sort 294 00:17:25,480 --> 00:17:28,439 Speaker 1: of hanging on to her left arm. In her right hand, 295 00:17:28,680 --> 00:17:32,880 Speaker 1: she has uh like some sort of a stone weapon, 296 00:17:33,400 --> 00:17:37,960 Speaker 1: like a wooden half with a with a stone blade, 297 00:17:38,000 --> 00:17:41,000 Speaker 1: some sort of like you know, primitive acts or club. 298 00:17:41,440 --> 00:17:44,520 Speaker 1: And she's staring back into the shadows behind her with 299 00:17:44,640 --> 00:17:47,560 Speaker 1: there's this kind of like cave environment, and there's clearly 300 00:17:47,800 --> 00:17:51,840 Speaker 1: an animal lurking there or an animal emerging from the shadows. 301 00:17:51,840 --> 00:17:53,960 Speaker 1: And I think this is supposed to be the other mother, 302 00:17:54,320 --> 00:17:56,720 Speaker 1: the mother that is hunting her. And I have no 303 00:17:56,800 --> 00:17:59,959 Speaker 1: idea of this. This this piece has has any connection 304 00:18:00,040 --> 00:18:01,840 Speaker 1: what we're talking about here, But it is interesting that 305 00:18:01,920 --> 00:18:07,080 Speaker 1: we do see left arm cradling children, right arm brandishing 306 00:18:07,080 --> 00:18:10,000 Speaker 1: a weapon to protect those children against some threat. 307 00:18:10,720 --> 00:18:12,399 Speaker 2: It is a kind of beautiful painting. Yeah. 308 00:18:12,520 --> 00:18:15,600 Speaker 1: Yeah, her hair is perfect too, like this mom's really 309 00:18:15,600 --> 00:18:19,280 Speaker 1: got it together, perfect hair, protecting the children, ready to 310 00:18:19,560 --> 00:18:22,480 Speaker 1: brain a panther with some sort of a stone weapon. 311 00:18:23,240 --> 00:18:27,600 Speaker 2: Anyway, whatever the cause of the right hand lateralization for 312 00:18:28,000 --> 00:18:33,520 Speaker 2: sequential motor control in throwing, The hypothesis goes on from 313 00:18:33,560 --> 00:18:37,920 Speaker 2: here to suggest that sequential motor control regions that made 314 00:18:37,960 --> 00:18:41,399 Speaker 2: us so good at tossing a stone with one hand 315 00:18:41,840 --> 00:18:47,720 Speaker 2: were eventually commondeered by selection pressure for communication and shifted 316 00:18:47,760 --> 00:18:50,840 Speaker 2: to a different kind of sequential motor control, which was 317 00:18:51,080 --> 00:18:54,320 Speaker 2: language production. Now, when we think of language production, we 318 00:18:54,359 --> 00:18:57,280 Speaker 2: think of speech, and that could be the case. I 319 00:18:57,400 --> 00:19:00,760 Speaker 2: think Calvin argued for a transitional state where the original 320 00:19:00,800 --> 00:19:04,560 Speaker 2: language was more gesture based, like gesturing with the hands maybe, 321 00:19:05,400 --> 00:19:10,000 Speaker 2: which would have then transitioned into speech production with the mouth. Again, 322 00:19:10,080 --> 00:19:12,520 Speaker 2: like many things here, that's not something we know for sure, 323 00:19:12,560 --> 00:19:14,800 Speaker 2: so we're in very speculative territory. But I do find 324 00:19:14,840 --> 00:19:18,199 Speaker 2: this really interesting. So again, if there's anything to this story, 325 00:19:18,520 --> 00:19:21,040 Speaker 2: it would go that for some reason, there is an 326 00:19:21,080 --> 00:19:26,000 Speaker 2: original right hand left brain motor lateralization for the majority 327 00:19:26,040 --> 00:19:29,840 Speaker 2: of the population for throwing objects. Human ancestors get really 328 00:19:29,880 --> 00:19:32,240 Speaker 2: good at throwing with that one hand, maybe cradling a 329 00:19:32,240 --> 00:19:35,560 Speaker 2: baby in the other arm or doing something else. And 330 00:19:35,600 --> 00:19:39,600 Speaker 2: then you could argue that the lateralization for precise sequential 331 00:19:39,600 --> 00:19:44,000 Speaker 2: motor activity and the left brain to power throwing eventually 332 00:19:44,040 --> 00:19:48,240 Speaker 2: provides the neurological scaffolding for the left brain's capacity for 333 00:19:48,400 --> 00:19:52,840 Speaker 2: language and speech. Now, what was the actual experiment in 334 00:19:53,040 --> 00:19:56,240 Speaker 2: this study, Well, it was looking at our closest primate 335 00:19:56,280 --> 00:20:00,280 Speaker 2: relatives to see if they could provide any insight on 336 00:20:00,720 --> 00:20:02,280 Speaker 2: what might have been going on in the brains of 337 00:20:02,400 --> 00:20:07,120 Speaker 2: very distant human ancestors. So they were looking at chimpanzees. Now, again, 338 00:20:07,200 --> 00:20:10,600 Speaker 2: chimpanzees don't throw nearly as well or as often as 339 00:20:10,640 --> 00:20:15,760 Speaker 2: we do, but some throw sometimes, So what if anything 340 00:20:15,920 --> 00:20:19,639 Speaker 2: is different in the brains of chimpanzees that reliably throw 341 00:20:20,000 --> 00:20:23,639 Speaker 2: versus those that don't. Specifically, the authors looked at the 342 00:20:23,760 --> 00:20:27,320 Speaker 2: ratio of two different types of brain tissue, white matter 343 00:20:27,400 --> 00:20:31,080 Speaker 2: and gray matter in the areas of chimpanzee brains that 344 00:20:31,119 --> 00:20:34,000 Speaker 2: would be most similar to the areas of the human 345 00:20:34,040 --> 00:20:37,600 Speaker 2: brain involved in motor control for throwing and for speech. 346 00:20:38,040 --> 00:20:41,119 Speaker 2: And this would be quote the homologue to Broca's area. 347 00:20:41,160 --> 00:20:44,520 Speaker 2: I remember again Broker's areas involved in speech production in humans. 348 00:20:45,119 --> 00:20:47,320 Speaker 2: And then they also say as well as the motor 349 00:20:47,480 --> 00:20:51,480 Speaker 2: hand area of the precentral gyrus termed the knob, K 350 00:20:51,640 --> 00:20:54,600 Speaker 2: and OB. And what they found was that in both 351 00:20:54,640 --> 00:20:58,000 Speaker 2: of these areas, in the chimpanzee equivalent of Broker's area 352 00:20:58,080 --> 00:21:01,000 Speaker 2: and in the knob. The ratio of white matter to 353 00:21:01,160 --> 00:21:06,000 Speaker 2: gray matter was higher in chimpanzees that throw versus those 354 00:21:06,040 --> 00:21:10,840 Speaker 2: that don't. Also quote, we further found that asymmetries in 355 00:21:10,920 --> 00:21:14,800 Speaker 2: white matter within both brain regions were larger in the 356 00:21:14,840 --> 00:21:20,679 Speaker 2: hemisphere contralateral to the chimpanzee's preferred throwing hand. So what 357 00:21:20,680 --> 00:21:22,920 Speaker 2: they're saying is it's not just that the ratio of 358 00:21:22,960 --> 00:21:25,440 Speaker 2: white matter was higher in these regions on both sides 359 00:21:25,480 --> 00:21:28,679 Speaker 2: of the brain. It's that whichever hand the chimpanzee liked 360 00:21:28,720 --> 00:21:32,880 Speaker 2: to throw with those particular regions had a higher proportion 361 00:21:33,000 --> 00:21:37,399 Speaker 2: of white matter on the opposite side of the brain. Also, 362 00:21:37,480 --> 00:21:40,960 Speaker 2: they assessed the chimpanzees in this study with what is 363 00:21:41,080 --> 00:21:46,040 Speaker 2: called a Primate Cognition Test BATTERY or pct B, which is, 364 00:21:46,480 --> 00:21:50,680 Speaker 2: you know, a sort of an SAT for chimpanzees, standard 365 00:21:50,840 --> 00:21:54,480 Speaker 2: tests on all kinds of mental abilities, you know, tons 366 00:21:54,520 --> 00:22:00,480 Speaker 2: of things, spatial memory, causality, inference, tool property, recognition, gaze following, 367 00:22:00,640 --> 00:22:03,200 Speaker 2: and so forth. And they were looking at, well, are 368 00:22:03,200 --> 00:22:06,840 Speaker 2: there any differences between apes that throw and apes that 369 00:22:07,040 --> 00:22:12,040 Speaker 2: don't throw? And out of this entire test battery generally 370 00:22:12,119 --> 00:22:15,840 Speaker 2: not generally, there were no cognitive differences except in one area. 371 00:22:16,000 --> 00:22:19,920 Speaker 2: There was only one aptitude where there was a significant difference, 372 00:22:20,400 --> 00:22:23,760 Speaker 2: and it was that researchers found chimpanzees that were more 373 00:22:23,760 --> 00:22:29,159 Speaker 2: inclined to throw were also better at social communication. So 374 00:22:29,240 --> 00:22:32,520 Speaker 2: the author's right quote. These results suggest that chimpanzees that 375 00:22:32,600 --> 00:22:37,280 Speaker 2: have learned to throw have developed greater cortical connectivity that's 376 00:22:37,400 --> 00:22:40,840 Speaker 2: correlating with the white matter between the primary motor cortex 377 00:22:41,240 --> 00:22:45,200 Speaker 2: and the Broca's area. Homologue, it is suggested that during 378 00:22:45,280 --> 00:22:49,320 Speaker 2: hominine evolution, after the split between lines leading to chimpanzees 379 00:22:49,359 --> 00:22:53,400 Speaker 2: and humans, there was intense selection on increased motor skills 380 00:22:53,440 --> 00:22:57,440 Speaker 2: associated with throwing, and that this potentially formed the foundation 381 00:22:57,640 --> 00:23:02,600 Speaker 2: for left hemisphere specialization associated with language and speech found 382 00:23:02,680 --> 00:23:06,399 Speaker 2: in modern humans. So this is another case where I 383 00:23:06,440 --> 00:23:08,560 Speaker 2: think this is far from proven. We would need much 384 00:23:08,600 --> 00:23:12,640 Speaker 2: more robust evidence before you could endorse this specific evolutionary 385 00:23:12,640 --> 00:23:17,399 Speaker 2: story as likely. But I find this very intriguing and 386 00:23:17,520 --> 00:23:20,080 Speaker 2: it does seem possible to me that the capacity for 387 00:23:20,240 --> 00:23:23,840 Speaker 2: throwing gave rise to the capacity for language. 388 00:23:24,920 --> 00:23:28,679 Speaker 1: So ape throws the bone, the bone spins around the 389 00:23:28,720 --> 00:23:33,080 Speaker 1: bone becomes a space station, just as Kubrick promised us. 390 00:23:33,200 --> 00:23:34,280 Speaker 2: Yeah, I didn't think about that. 391 00:23:34,359 --> 00:23:37,280 Speaker 1: Yeah, I want to get back into this idea of 392 00:23:37,720 --> 00:23:42,600 Speaker 1: early humans, especially throwing stones as weapons and throwing other 393 00:23:42,680 --> 00:23:45,200 Speaker 1: things as weapons. You know, as we discussed in the 394 00:23:45,240 --> 00:23:48,000 Speaker 1: last episode, we talked about some of the ideas concerning 395 00:23:48,000 --> 00:23:51,760 Speaker 1: the development of ranged weapon technology and prehistoric humans. This 396 00:23:51,880 --> 00:23:54,600 Speaker 1: idea that what first begins as a way of engaging 397 00:23:54,680 --> 00:23:59,040 Speaker 1: in agonistic communication could transform into just a way of 398 00:23:59,240 --> 00:24:03,000 Speaker 1: physically sin a message to another species via projectile. But 399 00:24:03,040 --> 00:24:05,760 Speaker 1: then eventually that begins to get into this way to 400 00:24:05,800 --> 00:24:09,720 Speaker 1: manipulate their behavior at range, especially in the case of 401 00:24:09,760 --> 00:24:12,639 Speaker 1: power scavenging, and ultimately it could be used as a 402 00:24:12,640 --> 00:24:15,399 Speaker 1: way to hunt prey animals. Right, And as we were 403 00:24:15,400 --> 00:24:18,880 Speaker 1: actually recording that episode, my mind kept turning to these 404 00:24:18,920 --> 00:24:22,960 Speaker 1: images of some sort of prehistoric warfare scenario in which 405 00:24:23,000 --> 00:24:27,480 Speaker 1: some you know, entirely too kubricky prehistoric people were employing 406 00:24:27,600 --> 00:24:31,200 Speaker 1: various weapons and kind of probably also probably a slightly 407 00:24:31,240 --> 00:24:34,240 Speaker 1: two table top war game manner where you have you know, 408 00:24:34,400 --> 00:24:38,159 Speaker 1: units of bone wielding beaters moving forward to engage in 409 00:24:38,200 --> 00:24:40,359 Speaker 1: some melee attacks, and then maybe you have some units 410 00:24:40,359 --> 00:24:43,639 Speaker 1: of rock throwers behind them, and you know this this 411 00:24:43,680 --> 00:24:45,639 Speaker 1: felt kind of silly in my head, maybe even a 412 00:24:45,680 --> 00:24:49,840 Speaker 1: little Gary Larson esque in my head, a little farside. 413 00:24:50,400 --> 00:24:53,080 Speaker 1: But then I started looking into it more because, of course, 414 00:24:53,119 --> 00:24:58,280 Speaker 1: you know, rock throwers were an important part of our history, 415 00:24:58,760 --> 00:25:01,160 Speaker 1: and when you start looking at into the history of 416 00:25:01,800 --> 00:25:06,320 Speaker 1: not only range weaponry, but hand range weaponry, it gets 417 00:25:06,320 --> 00:25:07,240 Speaker 1: pretty fascinating. 418 00:25:07,920 --> 00:25:09,800 Speaker 2: Well yeah, I mean, I think one of the main 419 00:25:09,840 --> 00:25:14,399 Speaker 2: things that striking is rediscovering how potent to force simple 420 00:25:14,520 --> 00:25:19,280 Speaker 2: thrown objects are, even in an era where powered projectile 421 00:25:19,320 --> 00:25:22,399 Speaker 2: technology like bows or crossbows or even guns exist. 422 00:25:23,240 --> 00:25:26,280 Speaker 1: When you think of somebody's throwing rocks, there at least 423 00:25:26,320 --> 00:25:29,359 Speaker 1: can be this sort of feeling that it's like a 424 00:25:29,440 --> 00:25:33,120 Speaker 1: juvenile sort of thing, that it's primitive, that it's a nuisance. 425 00:25:33,800 --> 00:25:35,679 Speaker 1: But on the other hand, I think most of us 426 00:25:35,720 --> 00:25:38,800 Speaker 1: realize that it's also quite dangerous. Nobody wants to be 427 00:25:38,880 --> 00:25:42,000 Speaker 1: hit in the head with a thrown rock. A well 428 00:25:42,000 --> 00:25:45,359 Speaker 1: aimed thrown rock can of course be deadly true, and 429 00:25:45,440 --> 00:25:47,600 Speaker 1: on top of that, a volley of thrown rocks from 430 00:25:47,680 --> 00:25:51,120 Speaker 1: multiple assailants even more dangerous. And of course we see 431 00:25:51,160 --> 00:25:53,720 Speaker 1: this reflected in the use of stoning as a form 432 00:25:53,720 --> 00:25:57,879 Speaker 1: of execution from ancient times through modern times. But I 433 00:25:57,880 --> 00:25:59,600 Speaker 1: didn't want to dwell so much on that because that's 434 00:26:00,359 --> 00:26:03,400 Speaker 1: more depressing subject matter. But I wanted to focus more 435 00:26:03,440 --> 00:26:06,480 Speaker 1: on hand thrown stones and weapons in a hunting and 436 00:26:06,560 --> 00:26:10,600 Speaker 1: warfare context. Okay, So I think for many of us, 437 00:26:10,600 --> 00:26:12,760 Speaker 1: and this was me until just the other day, we 438 00:26:12,840 --> 00:26:15,879 Speaker 1: tend to think of ranged weapons as this steady ascent 439 00:26:16,040 --> 00:26:18,879 Speaker 1: out of the Stone Age. So sure we threw stones 440 00:26:18,920 --> 00:26:22,560 Speaker 1: at things then, and we greatly increased our ability to 441 00:26:22,640 --> 00:26:26,600 Speaker 1: strategically employ those thrown stones, But then we got why, 442 00:26:26,640 --> 00:26:28,399 Speaker 1: and then of coach, we probably got wiser about how 443 00:26:28,440 --> 00:26:32,080 Speaker 1: we selected stones, granted, But then eventually we're gonna level up, right, 444 00:26:32,280 --> 00:26:36,959 Speaker 1: You're gonna upgrade to using something like a sling, a spear, 445 00:26:37,119 --> 00:26:40,800 Speaker 1: a spear thrower, a bow and arrow across bow, et cetera, 446 00:26:41,280 --> 00:26:43,399 Speaker 1: all the way up through the modern era. And I 447 00:26:43,440 --> 00:26:46,280 Speaker 1: think it's easy to think of this as a linear progression, 448 00:26:46,640 --> 00:26:49,760 Speaker 1: or like a video game skill tree, a situation where 449 00:26:49,760 --> 00:26:52,399 Speaker 1: you could you're yelling at the screen, Hey, don't equip 450 00:26:52,400 --> 00:26:54,639 Speaker 1: the throwing rock, you fool. You have a spear, Now 451 00:26:54,760 --> 00:26:55,520 Speaker 1: equip the spear. 452 00:26:56,240 --> 00:27:00,199 Speaker 2: Yes, yes, video game logic pervades our thoughts in every way. 453 00:27:00,280 --> 00:27:02,720 Speaker 1: Yeah, but of course this is not exactly how things 454 00:27:02,760 --> 00:27:05,639 Speaker 1: pan out for a number of reasons. Speaking broadly in 455 00:27:05,720 --> 00:27:09,600 Speaker 1: terms of just weaponry in general, materials are one factor, 456 00:27:09,960 --> 00:27:12,600 Speaker 1: and we've discussed that on the show before, but another 457 00:27:12,680 --> 00:27:16,000 Speaker 1: huge factor to consider is that humans are such great 458 00:27:16,080 --> 00:27:18,879 Speaker 1: natural throwers, as we've been discussing, and it's such a 459 00:27:18,920 --> 00:27:22,280 Speaker 1: big part of the weapon history, that there just may 460 00:27:22,320 --> 00:27:25,560 Speaker 1: not be a good reason to completely abandon the hand 461 00:27:25,640 --> 00:27:27,520 Speaker 1: thrown stone, right. 462 00:27:27,560 --> 00:27:29,960 Speaker 2: I mean, you can imagine cases where people are having 463 00:27:30,000 --> 00:27:34,400 Speaker 2: great success with just hand thrown stones, and why fix 464 00:27:34,440 --> 00:27:35,200 Speaker 2: what's not broken? 465 00:27:35,760 --> 00:27:40,000 Speaker 1: Yeah, And then if something also becomes a part of culture, 466 00:27:40,080 --> 00:27:43,200 Speaker 1: becomes a part of a martial art and a weapon tradition, 467 00:27:43,800 --> 00:27:47,160 Speaker 1: then there's this added incentive to keep it around. So 468 00:27:47,440 --> 00:27:52,199 Speaker 1: I started looking into some examples from Polynesian weaponry and 469 00:27:52,280 --> 00:27:54,840 Speaker 1: martial arts. The first thing I ran across was an 470 00:27:54,880 --> 00:27:59,000 Speaker 1: interesting mention in the Coming of the Mallori Weapons, a 471 00:27:59,240 --> 00:28:02,320 Speaker 1: nineteen forty nine text by New Zealand anthropologists and doctor 472 00:28:02,600 --> 00:28:06,520 Speaker 1: Tae Rangi Heroa who lived eighteen seventy seven through nineteen 473 00:28:06,600 --> 00:28:10,160 Speaker 1: fifty one, in discussing the prevalence for spears and clubs 474 00:28:10,200 --> 00:28:13,600 Speaker 1: in Polynesian history. He also discusses the swing as a 475 00:28:13,600 --> 00:28:17,280 Speaker 1: primary range weapon along with the spear, and then he 476 00:28:17,359 --> 00:28:21,240 Speaker 1: shares the following quote. Stones were also thrown by hand, 477 00:28:21,320 --> 00:28:24,280 Speaker 1: and early European voyagers have reported this form of attack 478 00:28:24,440 --> 00:28:27,200 Speaker 1: more than the use of the sling. The bow and arrow, 479 00:28:27,240 --> 00:28:30,119 Speaker 1: while present in some groups, was used for sport but 480 00:28:30,200 --> 00:28:32,800 Speaker 1: not as a weapon of war. In Samoa it was 481 00:28:32,880 --> 00:28:35,919 Speaker 1: used to shoot pigeons, in Hawaii to shoot rats, and 482 00:28:36,000 --> 00:28:39,280 Speaker 1: in the Society Islands it was a chiefly sport in 483 00:28:39,320 --> 00:28:43,520 Speaker 1: which archers clad in special costume shot for distance from 484 00:28:43,600 --> 00:28:47,760 Speaker 1: raised stone platforms. Now, obviously this is an older source here, 485 00:28:48,080 --> 00:28:50,520 Speaker 1: but instantly reading this he realized, well, this is true. 486 00:28:50,520 --> 00:28:54,200 Speaker 1: It raises interesting possibilities about the dependability of thrown stones 487 00:28:54,240 --> 00:28:58,440 Speaker 1: as weaponry even as other technologies come online. 488 00:28:58,640 --> 00:29:01,480 Speaker 2: Right, so you could have the technology of a bow 489 00:29:01,600 --> 00:29:05,560 Speaker 2: but still prefer hand thrown stones for some utilities. 490 00:29:06,240 --> 00:29:09,440 Speaker 1: Yeah, and the advantages of the bow, of course, are 491 00:29:09,440 --> 00:29:12,680 Speaker 1: well documented. You know, none of this that we're getting 492 00:29:12,680 --> 00:29:15,000 Speaker 1: into is going to be a statement that along the 493 00:29:15,040 --> 00:29:17,479 Speaker 1: lines of well, actually a throne rock is better than 494 00:29:17,520 --> 00:29:21,520 Speaker 1: a high power bow or anything like that. But it 495 00:29:21,600 --> 00:29:24,000 Speaker 1: is true that the use of the bow was widespread, 496 00:29:24,080 --> 00:29:27,080 Speaker 1: not only in ancient armies, but among hunter gatherers. But 497 00:29:27,200 --> 00:29:30,360 Speaker 1: as Thomas Hoolett points out in a section on ranged 498 00:29:30,400 --> 00:29:33,640 Speaker 1: weaponry in the book Seventy Great Inventions of the Ancient World, 499 00:29:33,840 --> 00:29:36,720 Speaker 1: not all hunter gatherers use the bow and arrow. He 500 00:29:36,840 --> 00:29:40,160 Speaker 1: mentions Australian Aborigines as an example of a people who 501 00:29:40,200 --> 00:29:43,960 Speaker 1: did not, despite some of them surely being aware of 502 00:29:44,000 --> 00:29:48,200 Speaker 1: the technology via contact with the Tarres Strait Islanders who 503 00:29:48,280 --> 00:29:52,160 Speaker 1: used bows. They were still people that retain the use 504 00:29:52,720 --> 00:29:57,160 Speaker 1: of ranged weaponry that depended on hand thrown objects, and 505 00:29:57,240 --> 00:30:01,280 Speaker 1: will come back to the most famous classification of hand 506 00:30:01,280 --> 00:30:04,200 Speaker 1: thrown objects that they used in a bit. But where 507 00:30:04,240 --> 00:30:07,760 Speaker 1: I really got fascinated with all of this was a 508 00:30:07,800 --> 00:30:11,160 Speaker 1: paper from twenty eleven. This was published in the Journal 509 00:30:11,280 --> 00:30:16,520 Speaker 1: of the Polynesian Society by Barbara Isaac and Grenaria Isaac 510 00:30:16,840 --> 00:30:21,840 Speaker 1: titled Unexpected Trajectories, a History of New Wayan Throwing Stones. 511 00:30:22,640 --> 00:30:26,600 Speaker 1: The authors here describe the warstones of New Way. New 512 00:30:26,600 --> 00:30:30,520 Speaker 1: Way is an island that's fifteen hundred miles or twenty 513 00:30:30,600 --> 00:30:35,280 Speaker 1: four hundred kilometers northeast of New Zealand, and when Captain 514 00:30:35,440 --> 00:30:38,480 Speaker 1: James Cook visited the island in seventeen seventy four. He 515 00:30:38,560 --> 00:30:41,920 Speaker 1: dubbed it the Savage Island, which may have had something 516 00:30:41,960 --> 00:30:45,520 Speaker 1: to do with their consumption of the native banana species, 517 00:30:45,560 --> 00:30:48,480 Speaker 1: which to understand had like a red peal and an 518 00:30:48,480 --> 00:30:52,760 Speaker 1: orangeish interior, and if in the teeth or rubbed on 519 00:30:52,800 --> 00:30:56,600 Speaker 1: the body, might look like blood. This also clearly reflects 520 00:30:56,640 --> 00:31:01,080 Speaker 1: Cook's general attitude towards indigenous peoples as well. But he 521 00:31:01,160 --> 00:31:05,320 Speaker 1: also certainly seemed to have encountered some difficulty in landing 522 00:31:05,800 --> 00:31:09,080 Speaker 1: on New Way. It's apparently difficult to land on the 523 00:31:09,160 --> 00:31:12,040 Speaker 1: island anyway due to the surrounding coral reefs, but the 524 00:31:12,080 --> 00:31:14,600 Speaker 1: people of New Way were also hostile to his landing 525 00:31:14,640 --> 00:31:18,720 Speaker 1: attempts and his naturalists. The naturalist on this particular voyage, 526 00:31:18,840 --> 00:31:22,040 Speaker 1: Andrews Sparman, was injured by a thrown stone. I believe 527 00:31:22,040 --> 00:31:26,080 Speaker 1: it got him in the arm. The New Way here 528 00:31:27,080 --> 00:31:30,160 Speaker 1: they were not just picking up random stones and throwing 529 00:31:30,200 --> 00:31:33,479 Speaker 1: them either. This is where it gets really fascinating. They 530 00:31:33,480 --> 00:31:36,440 Speaker 1: had a highly refined approach to the use of hand 531 00:31:36,480 --> 00:31:41,200 Speaker 1: thrown ranged stone weaponry. According to Isaac and Isaac, the 532 00:31:41,280 --> 00:31:44,520 Speaker 1: warriors were reported at the time to each have spears 533 00:31:44,560 --> 00:31:46,720 Speaker 1: on their person, to have a swing and also have 534 00:31:46,800 --> 00:31:51,040 Speaker 1: a pouch of stones for throwing. But throwing stones and 535 00:31:51,080 --> 00:31:54,360 Speaker 1: sling launch stones were not uncommon among other people who 536 00:31:54,360 --> 00:31:58,680 Speaker 1: were encountered on islands from this vast region, so comparatively, 537 00:31:58,720 --> 00:32:02,800 Speaker 1: there wasn't much Western commentary on these throwing stones. But 538 00:32:03,280 --> 00:32:06,840 Speaker 1: the throwing stones of New Way, according to Isaac and Isaac, 539 00:32:06,880 --> 00:32:09,560 Speaker 1: were quite singular, and much of it would come out 540 00:32:09,680 --> 00:32:15,240 Speaker 1: later through indigenous recollections, the work of later anthropologists and missionaries, 541 00:32:15,600 --> 00:32:18,680 Speaker 1: as well as later analysis of stones that were subsequently 542 00:32:18,720 --> 00:32:30,440 Speaker 1: taken off the island after Western contact. 543 00:32:32,120 --> 00:32:33,120 Speaker 2: So these war. 544 00:32:33,040 --> 00:32:36,440 Speaker 1: Stones, the crazy thing about them is that, again these 545 00:32:36,440 --> 00:32:38,160 Speaker 1: are not just stones that were picked up or even 546 00:32:38,280 --> 00:32:42,880 Speaker 1: stones that were sort of painstakingly collected and the way 547 00:32:42,920 --> 00:32:48,440 Speaker 1: that one might scour the rocks by a stream to 548 00:32:48,480 --> 00:32:53,240 Speaker 1: find the best rocks for skipping. Now, these were crafted items, 549 00:32:53,280 --> 00:32:58,480 Speaker 1: made of I think predominantly limestone crafted items. 550 00:32:58,480 --> 00:33:00,640 Speaker 2: So you might think of this as more like an 551 00:33:00,840 --> 00:33:03,200 Speaker 2: arrow or an axe head or something, but it is 552 00:33:03,240 --> 00:33:06,560 Speaker 2: a stone for throwing with the hand right right. 553 00:33:07,120 --> 00:33:11,040 Speaker 1: The people here would harvest the stone, apparently from stalactites 554 00:33:11,400 --> 00:33:16,080 Speaker 1: and stalagmites in naturally occurring caves on the island and 555 00:33:16,120 --> 00:33:20,200 Speaker 1: then wear them down into the desired shape by working 556 00:33:20,240 --> 00:33:23,560 Speaker 1: them over with other pieces of stone or with pieces 557 00:33:23,600 --> 00:33:28,600 Speaker 1: of coral. So we're talking considerable manufacturing effort going into these. Again, 558 00:33:28,840 --> 00:33:30,960 Speaker 1: they're not just picked up off the ground. They're not 559 00:33:31,000 --> 00:33:35,480 Speaker 1: even scavenge from the ground. They are manufactured from materials 560 00:33:35,480 --> 00:33:38,160 Speaker 1: that are harvested. They tended to weigh around three to 561 00:33:38,200 --> 00:33:42,360 Speaker 1: four pounds each and they were largely spherical in shape. 562 00:33:43,240 --> 00:33:47,880 Speaker 1: They were often compared to small cannon balls by Western commentators, 563 00:33:48,480 --> 00:33:51,520 Speaker 1: but the difference is that they were elongated a little 564 00:33:51,560 --> 00:33:54,360 Speaker 1: bit on the two opposing ends. You can look up 565 00:33:54,400 --> 00:33:58,880 Speaker 1: pictures of these online and to me, if I was 566 00:33:58,880 --> 00:34:02,240 Speaker 1: to compare them to a naturally occurring object, I would 567 00:34:02,240 --> 00:34:05,880 Speaker 1: say they kind of look like like well crafted stone, 568 00:34:06,040 --> 00:34:07,160 Speaker 1: lemons or limes. 569 00:34:07,440 --> 00:34:09,560 Speaker 2: I was gonna say, lemon, yeah. 570 00:34:09,239 --> 00:34:12,520 Speaker 1: Yeah, so yeah they have that. Or I guess you 571 00:34:12,520 --> 00:34:15,000 Speaker 1: could almost say they don't really look like a football, 572 00:34:15,400 --> 00:34:18,880 Speaker 1: but they have I guess, a slightly football esque shape, 573 00:34:19,320 --> 00:34:23,839 Speaker 1: or they remind me of certain like malformed or not malformed, 574 00:34:23,880 --> 00:34:26,920 Speaker 1: but sort of slightly unrealistic toy footballs you might have 575 00:34:27,000 --> 00:34:29,400 Speaker 1: seen if you were a child, you know, back in 576 00:34:29,400 --> 00:34:30,400 Speaker 1: the eighties or something. 577 00:34:31,040 --> 00:34:33,319 Speaker 2: Sorry, I was just briefly amused by the concept of 578 00:34:33,320 --> 00:34:34,280 Speaker 2: a toy football. 579 00:34:35,760 --> 00:34:39,520 Speaker 1: Well, well, you have the functional football. It's for serious business, 580 00:34:39,560 --> 00:34:43,080 Speaker 1: for the sport of American football. And then you have 581 00:34:43,160 --> 00:34:44,680 Speaker 1: something that's that's less serious. 582 00:34:45,000 --> 00:34:46,879 Speaker 2: This is a football, this is not for playing with. 583 00:34:48,960 --> 00:34:51,440 Speaker 1: So you did have Western observers, though, that were figuring 584 00:34:51,480 --> 00:34:53,960 Speaker 1: a lot of this out, that these warstones were indeed 585 00:34:54,000 --> 00:34:57,840 Speaker 1: crafted items, that they were made out of limestone, that 586 00:34:57,880 --> 00:35:01,800 Speaker 1: people would harvest the stone from against stalactites and stalagmites, 587 00:35:02,320 --> 00:35:06,719 Speaker 1: And there's some really interesting takes on this that are 588 00:35:06,719 --> 00:35:11,120 Speaker 1: reported in this paper. In eighteen sixty eight, Missionary Thomas 589 00:35:11,160 --> 00:35:14,440 Speaker 1: Powell wrote that quote this fact is remarkable as an 590 00:35:14,480 --> 00:35:18,040 Speaker 1: indication of thought and design natural to this people. For 591 00:35:18,480 --> 00:35:21,279 Speaker 1: it is not probable that the first inhabitants brought the 592 00:35:21,360 --> 00:35:25,000 Speaker 1: ideas with them. But they found this limestone in the caves, 593 00:35:25,200 --> 00:35:27,879 Speaker 1: saw the use to which it might be put, and 594 00:35:28,200 --> 00:35:32,080 Speaker 1: designed the shape. It is therefore original on their part, 595 00:35:32,160 --> 00:35:35,680 Speaker 1: and in this particular they anticipated the European science of 596 00:35:35,719 --> 00:35:39,560 Speaker 1: the recent century. Now they don't note what he was 597 00:35:39,600 --> 00:35:42,520 Speaker 1: referring to here on the European science thing. I'm thinking 598 00:35:42,560 --> 00:35:44,880 Speaker 1: maybe airships. I'm not sure. They kind of have an 599 00:35:44,880 --> 00:35:50,000 Speaker 1: airship look to him, I guess. Now. On the limestone front, 600 00:35:50,480 --> 00:35:54,759 Speaker 1: nineteenth and twentieth century anthropologists described other warstones that were 601 00:35:54,840 --> 00:35:57,919 Speaker 1: sometimes used that might have been made of other materials 602 00:35:59,120 --> 00:36:03,200 Speaker 1: of basalt of coral, for example. You definitely have examples. 603 00:36:02,840 --> 00:36:04,040 Speaker 2: Of like a black. 604 00:36:05,280 --> 00:36:08,320 Speaker 1: Stone of black war stone, but limestone seems to be 605 00:36:08,400 --> 00:36:12,800 Speaker 1: the primary material. They were highly prized and were used 606 00:36:12,840 --> 00:36:17,000 Speaker 1: exclusively for conflict, and there was apparently a lot of 607 00:36:17,040 --> 00:36:19,759 Speaker 1: conflict on the on the island. You know, this is 608 00:36:19,960 --> 00:36:22,200 Speaker 1: before there were any Westerners even, and part of it 609 00:36:22,200 --> 00:36:24,719 Speaker 1: had to do with you know, droughts would occur and 610 00:36:24,760 --> 00:36:29,680 Speaker 1: there was a lot of skirmishing for available resources. But 611 00:36:29,760 --> 00:36:32,560 Speaker 1: they didn't hunt with them apparently, So birds were hunted 612 00:36:32,600 --> 00:36:35,920 Speaker 1: with what are referred to as bird bows in this paper, 613 00:36:36,480 --> 00:36:40,040 Speaker 1: and fish were hunted with nets. So these were exclusively 614 00:36:40,160 --> 00:36:45,719 Speaker 1: for dealing with human threats or perceived human threats. Warriors 615 00:36:45,760 --> 00:36:48,799 Speaker 1: would carry them in bags or on belts, and if 616 00:36:48,800 --> 00:36:50,680 Speaker 1: they ran out of ammo, it's mentioned that they would 617 00:36:50,760 --> 00:36:53,000 Speaker 1: naturally make use of stones from the ground as well, 618 00:36:53,080 --> 00:36:55,960 Speaker 1: so they weren't above you know, reaching down and grabbing 619 00:36:55,960 --> 00:36:59,680 Speaker 1: whatever was available and throwing that after your special stones 620 00:36:59,760 --> 00:37:03,680 Speaker 1: were extinguished, and then of course after a skirmish or battle, 621 00:37:04,280 --> 00:37:06,279 Speaker 1: you would hopefully be able to go back and pick 622 00:37:06,360 --> 00:37:11,480 Speaker 1: up your AMMO retrieve them. Because other sources mentioned that 623 00:37:11,520 --> 00:37:15,759 Speaker 1: they often they had names, they had histories, histories of violence, 624 00:37:16,200 --> 00:37:19,440 Speaker 1: and so these particular stones would kind of resonate with 625 00:37:19,520 --> 00:37:22,120 Speaker 1: importance to the individual who wielded it. 626 00:37:23,760 --> 00:37:27,759 Speaker 2: So it's interesting that if the stones are you know, 627 00:37:27,800 --> 00:37:31,520 Speaker 2: they're they're manufactured with care, and they're used specifically for 628 00:37:31,680 --> 00:37:35,480 Speaker 2: human conflict instead of hunting. I mean, it makes me 629 00:37:35,560 --> 00:37:38,719 Speaker 2: think about them them having i don't know, some kind 630 00:37:38,719 --> 00:37:42,000 Speaker 2: of special like communicative or signaling power in addition to 631 00:37:42,080 --> 00:37:44,320 Speaker 2: their ability to hit and hurt someone. 632 00:37:45,040 --> 00:37:49,400 Speaker 1: Yeah, yeah, I think so. Here's another great quote. This 633 00:37:49,440 --> 00:37:51,799 Speaker 1: one is if it's in the paper as well, from 634 00:37:52,080 --> 00:37:56,320 Speaker 1: anthropologists Edwin Loewe, who wrote the following about the importance 635 00:37:56,320 --> 00:37:59,480 Speaker 1: of the stones. The individuals quote the fighting stones all 636 00:37:59,520 --> 00:38:02,520 Speaker 1: had special names, and they were put in a kafa 637 00:38:02,920 --> 00:38:06,960 Speaker 1: or girdle, which was plated like a matt. The kafa 638 00:38:07,080 --> 00:38:10,240 Speaker 1: was about six to seven inches wide and was customarily 639 00:38:10,400 --> 00:38:14,680 Speaker 1: four fathoms in length. The third night before the war arrived, 640 00:38:15,320 --> 00:38:19,080 Speaker 1: they wound the kafa around their stomachs and slept in 641 00:38:19,080 --> 00:38:23,319 Speaker 1: this manner during the night, neither eating or drinking. So 642 00:38:23,440 --> 00:38:28,479 Speaker 1: in this paper, the authors here they point out that 643 00:38:29,200 --> 00:38:32,960 Speaker 1: these new weeg In stones, these war stones, there were 644 00:38:33,040 --> 00:38:37,640 Speaker 1: songs about them, and part of their importance also may 645 00:38:37,680 --> 00:38:39,040 Speaker 1: have had to do with the fact that they were 646 00:38:39,080 --> 00:38:43,960 Speaker 1: products of the caves, which were sacred sites with seems 647 00:38:43,960 --> 00:38:46,200 Speaker 1: like connections to the afterlife, And of course this matches 648 00:38:46,280 --> 00:38:49,759 Speaker 1: up with the way caves were viewed by peoples and 649 00:38:49,800 --> 00:38:52,520 Speaker 1: other parts of the world as well. The stones were 650 00:38:52,640 --> 00:38:56,640 Speaker 1: used in ambush attacks, in skirmishes, but also sometimes in 651 00:38:56,680 --> 00:39:00,160 Speaker 1: fights to the death would occur, but it seems like 652 00:39:00,200 --> 00:39:04,200 Speaker 1: a lot of these battles, based on some of the commentaries, 653 00:39:05,440 --> 00:39:09,680 Speaker 1: may not have been typically that lethal. So yeah, this 654 00:39:09,719 --> 00:39:12,399 Speaker 1: does line up with this idea of communication. It's not 655 00:39:12,440 --> 00:39:16,719 Speaker 1: necessarily about going out and absolutely murdering the competition, but 656 00:39:17,000 --> 00:39:20,360 Speaker 1: driving them away from resources that you're looking to control. 657 00:39:21,840 --> 00:39:25,279 Speaker 1: And in the paper, the authors also mostly speculate on 658 00:39:25,480 --> 00:39:28,920 Speaker 1: accuracy here, and part of this was based on accounts 659 00:39:28,920 --> 00:39:33,080 Speaker 1: of other throwing techniques by other advanced stone or club 660 00:39:33,160 --> 00:39:37,560 Speaker 1: throwing groups, but they speculate that high accuracy was likely 661 00:39:37,640 --> 00:39:41,560 Speaker 1: within twenty yards or eighteen meters roughly, but greater distance 662 00:39:41,680 --> 00:39:45,120 Speaker 1: accuracy was certainly possible. And I think this makes sense 663 00:39:45,160 --> 00:39:49,400 Speaker 1: when you consider the likely scenarios in which these stones 664 00:39:49,400 --> 00:39:52,960 Speaker 1: are being used. So yeah, any kind of sort of 665 00:39:53,160 --> 00:39:57,240 Speaker 1: tabletop gaming scenario that you have in your mind should 666 00:39:57,239 --> 00:39:59,840 Speaker 1: probably set aside. It sounds like most of these the 667 00:40:00,000 --> 00:40:03,680 Speaker 1: the encounters these battles would have involved like one individual 668 00:40:03,719 --> 00:40:06,640 Speaker 1: against one another individual or one small group against another. 669 00:40:06,880 --> 00:40:10,440 Speaker 1: It seems like skirmishes and small ambushes were sort of 670 00:40:10,440 --> 00:40:16,200 Speaker 1: the typical encounter context for their usage. So anyway, it's 671 00:40:16,200 --> 00:40:20,360 Speaker 1: a fascinating paper. It's available on jay Store if anyone 672 00:40:20,400 --> 00:40:23,000 Speaker 1: wants to read more. They really get in depth about 673 00:40:23,040 --> 00:40:26,600 Speaker 1: the history of it and various mostly Western commentators who 674 00:40:26,640 --> 00:40:29,279 Speaker 1: are looking at it, and also how the use of 675 00:40:29,320 --> 00:40:34,560 Speaker 1: the stones was disappeared and then the stones went out 676 00:40:35,040 --> 00:40:37,759 Speaker 1: throughout the world and then were to certain degrees brought 677 00:40:37,760 --> 00:40:41,000 Speaker 1: back or studied. Now, this was certainly the most to 678 00:40:41,040 --> 00:40:44,080 Speaker 1: me anyway remarkable account of stone throwing I came across, 679 00:40:44,600 --> 00:40:48,279 Speaker 1: but not the only account of specialized throwing stones. I 680 00:40:48,360 --> 00:40:54,279 Speaker 1: ran across the work of Guy Steibel talking about archaeology 681 00:40:54,280 --> 00:40:58,880 Speaker 1: finds in Jerusalem and the accumulated weapons and AMMO that 682 00:40:58,920 --> 00:41:02,319 Speaker 1: they were finding. This was a paper that came out 683 00:41:02,320 --> 00:41:03,360 Speaker 1: on twenty thirteen. 684 00:41:03,880 --> 00:41:04,319 Speaker 2: This is from a. 685 00:41:04,360 --> 00:41:09,120 Speaker 1: Chapter titled Military Equipment in a larger collection of papers 686 00:41:09,280 --> 00:41:17,000 Speaker 1: titled Jerusalem Excavations in the Tiropean Valley. And yeah, there's 687 00:41:17,040 --> 00:41:19,160 Speaker 1: a lot of discussion of things like the things you 688 00:41:19,160 --> 00:41:23,200 Speaker 1: would expect to find, sling stones and so forth, other 689 00:41:23,280 --> 00:41:27,439 Speaker 1: types of projectiles. But then there's an interesting part where 690 00:41:27,480 --> 00:41:31,080 Speaker 1: he mentions he starts talking about what may have been 691 00:41:31,400 --> 00:41:36,920 Speaker 1: stones that were expressly collected and even crafted for throwing. 692 00:41:37,520 --> 00:41:41,600 Speaker 1: Quote three flint balls have a single flat face, unlike 693 00:41:41,680 --> 00:41:46,040 Speaker 1: weights or grinding stones that frequently exhibit multiple flat surfaces. 694 00:41:46,360 --> 00:41:49,359 Speaker 1: They were ideal for heaping on top of battlements, as 695 00:41:49,440 --> 00:41:53,279 Speaker 1: modern experiments have demonstrated. In light of parallels from both 696 00:41:53,360 --> 00:41:57,160 Speaker 1: Palestine and the Roman West, it appears that the use 697 00:41:57,200 --> 00:41:59,880 Speaker 1: of hand thrown stones was much more prevalent than had 698 00:42:00,120 --> 00:42:02,799 Speaker 1: been previously appreciated in modern scholarship. 699 00:42:03,239 --> 00:42:06,799 Speaker 2: Oh, that's interesting. The single flat face. So that would 700 00:42:06,800 --> 00:42:10,520 Speaker 2: be a stone that was modified or selected to have 701 00:42:10,560 --> 00:42:12,920 Speaker 2: a single flat face in order to make it easier 702 00:42:12,960 --> 00:42:15,840 Speaker 2: to stack in a pile, and so it wouldn't roll away. 703 00:42:16,480 --> 00:42:19,279 Speaker 1: Yeah, yeah, for use on battlements, which I guess also 704 00:42:19,320 --> 00:42:21,040 Speaker 1: the other side of that is, not only do you 705 00:42:21,200 --> 00:42:24,200 Speaker 1: not want your AMMO to roll away, you don't want 706 00:42:24,239 --> 00:42:27,840 Speaker 1: it to roll off the battlements with you know, fatal 707 00:42:27,880 --> 00:42:34,120 Speaker 1: gravity of sense potentially if you're not meaning to drop it. Yeah, 708 00:42:34,800 --> 00:42:38,960 Speaker 1: I've never thought about this before. I mean, I've certainly 709 00:42:39,480 --> 00:42:44,160 Speaker 1: researched siege scenarios before, where it's very obvious that if 710 00:42:44,160 --> 00:42:47,160 Speaker 1: you have the advantage of battlements, there's a great deal 711 00:42:47,200 --> 00:42:50,480 Speaker 1: you can do without the need for the power of 712 00:42:50,520 --> 00:42:53,520 Speaker 1: a bow. You can just drop things on people underneath. 713 00:42:53,760 --> 00:42:57,000 Speaker 1: And it was dropping things on your besiegers was a 714 00:42:57,880 --> 00:43:00,319 Speaker 1: favorite tactic. Be that you could drop rock, you could 715 00:43:00,360 --> 00:43:05,080 Speaker 1: drop various burning things, oils, et cetera, all manner of things, 716 00:43:05,320 --> 00:43:09,120 Speaker 1: and again with lethal intensity. But this idea of not 717 00:43:09,200 --> 00:43:11,440 Speaker 1: just having stones, but stones that had been to some 718 00:43:11,520 --> 00:43:15,520 Speaker 1: degree altered or manufactured or crafted in order to just 719 00:43:15,560 --> 00:43:17,520 Speaker 1: stack up there so they're ready to go, but they're 720 00:43:17,520 --> 00:43:21,640 Speaker 1: also not rolling out of sight and posing a danger 721 00:43:22,120 --> 00:43:34,759 Speaker 1: to anyone who might just say, be working beneath. Now, 722 00:43:34,800 --> 00:43:38,879 Speaker 1: there are also several interesting cases, probably many many more 723 00:43:39,400 --> 00:43:41,400 Speaker 1: on top of what I'm going to highlight here of 724 00:43:41,560 --> 00:43:45,120 Speaker 1: hand thrown clubs and throwing sticks. So you know, we've 725 00:43:45,160 --> 00:43:48,000 Speaker 1: been talking about throwing rocks, but of course throwing sticks 726 00:43:48,440 --> 00:43:50,799 Speaker 1: is just sort of the other side of the equation here, 727 00:43:51,160 --> 00:43:54,160 Speaker 1: and you find example of these traditions just throughout the 728 00:43:54,200 --> 00:43:58,520 Speaker 1: world on various continents. The throwing stick was used as 729 00:43:58,560 --> 00:44:01,880 Speaker 1: a hunting tool by prehistoric peoples, and we have examples 730 00:44:01,960 --> 00:44:05,360 Speaker 1: of these going back at least some three hundred thousand years. 731 00:44:05,880 --> 00:44:08,560 Speaker 1: One of the problems that this is something that's pointed 732 00:44:08,600 --> 00:44:11,200 Speaker 1: out in a paper I was looking at by Conrad 733 00:44:11,280 --> 00:44:14,279 Speaker 1: at All in nature, ecology and evolution, is that a 734 00:44:14,360 --> 00:44:18,120 Speaker 1: throwing stick is generally a wooden stick, and therefore it's 735 00:44:18,120 --> 00:44:21,360 Speaker 1: not always going to survive to become an artifact that 736 00:44:21,400 --> 00:44:25,200 Speaker 1: can be studied and interpreted, you know, hundreds of thousands 737 00:44:25,320 --> 00:44:29,560 Speaker 1: of years later. But the practice of hunting with thrown 738 00:44:29,600 --> 00:44:33,960 Speaker 1: sticks certainly survived. The ancient Egyptians retained a practice of 739 00:44:34,080 --> 00:44:38,120 Speaker 1: hunting with throwing sticks, and we see this commemorated both 740 00:44:38,120 --> 00:44:43,080 Speaker 1: in their hieroglyphics but also in art. I included an 741 00:44:43,120 --> 00:44:44,680 Speaker 1: image for you to look at here, Joe, where you 742 00:44:44,719 --> 00:44:48,880 Speaker 1: see an individual clearly out by the water side. There 743 00:44:48,880 --> 00:44:52,239 Speaker 1: are all these birds around and in one hand the 744 00:44:52,280 --> 00:44:55,160 Speaker 1: individual was holding up this throwing stick. 745 00:44:55,520 --> 00:44:59,040 Speaker 2: And this is sort of an an induated club of 746 00:44:59,120 --> 00:45:00,360 Speaker 2: sorts that can be thrown. 747 00:45:01,239 --> 00:45:03,879 Speaker 1: Yeah. Yeah, and I mean we also see the use 748 00:45:03,920 --> 00:45:06,080 Speaker 1: of this in other cultures as well. The hope He 749 00:45:06,120 --> 00:45:08,360 Speaker 1: tribes people of North America also used a type of 750 00:45:08,440 --> 00:45:11,399 Speaker 1: hunting sticks, sometimes referred to as a rabbit stick name 751 00:45:11,520 --> 00:45:14,840 Speaker 1: for the prey. You would go after this with this tool, 752 00:45:14,920 --> 00:45:19,680 Speaker 1: with this weapon. Throwing clubs throwing sticks were also used 753 00:45:19,680 --> 00:45:26,880 Speaker 1: in warfare scenarios and also in war related ceremonies and symbolism. 754 00:45:27,160 --> 00:45:31,839 Speaker 1: Fiji Islanders used beautiful and ceremonial throwing war clubs. These 755 00:45:31,880 --> 00:45:35,000 Speaker 1: were called ulahs, and you can look up examples of these. 756 00:45:36,040 --> 00:45:39,000 Speaker 1: Some key African traditions of throwing clubs are notable as well, 757 00:45:39,000 --> 00:45:43,480 Speaker 1: including the East African rungu as well as the knob 758 00:45:43,600 --> 00:45:47,799 Speaker 1: carry of southern and Eastern Africa. And these were used 759 00:45:47,840 --> 00:45:50,960 Speaker 1: for hunting in war, but also became highly symbolic social 760 00:45:51,000 --> 00:45:54,760 Speaker 1: signifiers as well. Yeah, but I feel like the idea 761 00:45:54,920 --> 00:45:59,000 Speaker 1: that the thrown blunt weapon the throwing club is something 762 00:45:59,040 --> 00:46:03,879 Speaker 1: that is often I guess glossed over in at least 763 00:46:03,880 --> 00:46:07,200 Speaker 1: in the Western mindset, you know, just again coming back 764 00:46:07,239 --> 00:46:09,400 Speaker 1: as always to things like Dungeons and Dragons, where we 765 00:46:10,040 --> 00:46:14,760 Speaker 1: wrap all these fantasy scenarios around the use of ranged 766 00:46:14,800 --> 00:46:18,839 Speaker 1: in melee weaponry. It's easy to dismiss the idea that, yeah, 767 00:46:18,840 --> 00:46:22,440 Speaker 1: that the club also is a potential range weapon, though 768 00:46:22,480 --> 00:46:24,800 Speaker 1: of course, I think Dungeons and Dragons does at least 769 00:46:24,960 --> 00:46:28,920 Speaker 1: have a boomerang in it, And the boomerang is probably 770 00:46:29,040 --> 00:46:33,160 Speaker 1: the most famous, and I guess the most exceptional of 771 00:46:33,320 --> 00:46:37,560 Speaker 1: the throne clubs that humans have developed over the ages. 772 00:46:38,560 --> 00:46:42,600 Speaker 1: The boomerang is exceptional because it's still essentially a throne 773 00:46:42,600 --> 00:46:45,799 Speaker 1: club that kills or injures via blunt force, but it 774 00:46:45,840 --> 00:46:49,879 Speaker 1: is also crafted to spin in just the right way 775 00:46:49,960 --> 00:46:54,400 Speaker 1: and by virtue of its shape, to generate an aerofoil, 776 00:46:54,840 --> 00:46:58,200 Speaker 1: which then increases the distance that it can be thrown. 777 00:46:58,320 --> 00:47:01,280 Speaker 1: So it's not only you know, throne but it also 778 00:47:01,760 --> 00:47:05,240 Speaker 1: begins to take on flight in a fascinating manner. 779 00:47:05,600 --> 00:47:09,239 Speaker 2: Yeah. I remember being fascinated by the boomerang as far 780 00:47:09,280 --> 00:47:10,640 Speaker 2: back as when I was a little kid. 781 00:47:11,360 --> 00:47:15,000 Speaker 1: Yeah, And according to Thomas Hewlett, we run into the 782 00:47:15,000 --> 00:47:19,880 Speaker 1: wooden artifact problem again with boomerangs, but convincing boomerangs have 783 00:47:19,960 --> 00:47:23,840 Speaker 1: been discovered as old as ten thousand years, so they've 784 00:47:23,880 --> 00:47:27,080 Speaker 1: been around for quite a while. There are returning boomerangs 785 00:47:27,080 --> 00:47:33,200 Speaker 1: and their non returning boomerangs. Non returning boomerangs were primarily weapons, 786 00:47:33,320 --> 00:47:36,960 Speaker 1: while returning boomerangs were I think more in the recreational 787 00:47:37,000 --> 00:47:40,919 Speaker 1: and symbolic and mythological sphere of things, but could also 788 00:47:41,040 --> 00:47:45,040 Speaker 1: be used apparently in hunting scenarios as some sort of 789 00:47:45,160 --> 00:47:48,440 Speaker 1: decoy for I think, birds of prey, but also as 790 00:47:48,480 --> 00:47:51,160 Speaker 1: a means of frightening and tended bird prey, So they 791 00:47:51,160 --> 00:47:55,880 Speaker 1: weren't without functional uses. And there are a lot of 792 00:47:55,880 --> 00:47:58,440 Speaker 1: things similar to these boomerangs that we find in other 793 00:47:58,560 --> 00:48:00,799 Speaker 1: cultures as well, like the Tamil people had a kind 794 00:48:00,840 --> 00:48:04,200 Speaker 1: of non returning boomerang of their own called a valari, 795 00:48:04,680 --> 00:48:07,360 Speaker 1: and you can look up various images of this as well. 796 00:48:07,880 --> 00:48:11,440 Speaker 1: Has a slight boomerang shape, kind of a tusk like shape. 797 00:48:13,320 --> 00:48:16,439 Speaker 1: Now going back to Thomas Coulett here, he points out 798 00:48:16,480 --> 00:48:20,120 Speaker 1: that broadly speaking, the evolution of range weaponry was initially 799 00:48:21,160 --> 00:48:23,200 Speaker 1: an evolution that had a lot to do with range. 800 00:48:23,520 --> 00:48:26,920 Speaker 1: Thrown weapons greatly increase the range at which human beings 801 00:48:27,560 --> 00:48:32,120 Speaker 1: may inflict harm. But then additional throwing technologies extend that range, 802 00:48:32,280 --> 00:48:34,480 Speaker 1: and this of course increases what we can do with 803 00:48:34,520 --> 00:48:38,400 Speaker 1: them from a hunting standpoint, but also provides advantages over 804 00:48:38,719 --> 00:48:42,440 Speaker 1: other human adversaries, at least under the right conditions. But 805 00:48:42,480 --> 00:48:44,400 Speaker 1: I think these examples show that it's not just a 806 00:48:44,440 --> 00:48:47,839 Speaker 1: matter of abandoning the use of hand thrown projectiles. We 807 00:48:47,920 --> 00:48:51,200 Speaker 1: retain the physical abilities as well as the basic skill sets, 808 00:48:51,640 --> 00:48:54,200 Speaker 1: and we see this reflected in our sports as well 809 00:48:54,200 --> 00:48:57,960 Speaker 1: as our weapon cultures. Hand thrown weapon traditions clearly survived 810 00:48:58,000 --> 00:49:01,200 Speaker 1: the advent of other range weapon technologies and in many 811 00:49:01,239 --> 00:49:06,480 Speaker 1: cases retained important cultural values as well. And there's one 812 00:49:06,480 --> 00:49:09,640 Speaker 1: final wrinkle here too that I almost completely blanked on. 813 00:49:09,760 --> 00:49:11,799 Speaker 1: I almost didn't have anything about this in the notes, 814 00:49:11,840 --> 00:49:14,520 Speaker 1: but then I of course remembered well. As we enter 815 00:49:14,560 --> 00:49:18,960 Speaker 1: into the age of explosives, hand thrown weaponry remains important 816 00:49:19,080 --> 00:49:22,200 Speaker 1: in the form of hand grenades. The more common variety 817 00:49:22,200 --> 00:49:24,840 Speaker 1: of grenade is of course made to be thrown by hand, 818 00:49:24,920 --> 00:49:27,880 Speaker 1: much like a throwing stone, more or less fits in 819 00:49:27,880 --> 00:49:30,759 Speaker 1: the human palm, though we also have the example of 820 00:49:30,760 --> 00:49:33,200 Speaker 1: the German stick hand grenade that was used in the 821 00:49:33,239 --> 00:49:35,640 Speaker 1: first and Second World Wars, and I think adopted by 822 00:49:36,080 --> 00:49:38,200 Speaker 1: some other groups as well during this period. But as 823 00:49:38,239 --> 00:49:42,480 Speaker 1: the name implies, this design features a long handle, and 824 00:49:42,520 --> 00:49:45,520 Speaker 1: these were thrown end over end, much like a hunting 825 00:49:45,600 --> 00:49:48,840 Speaker 1: stick or a thrown club. Now, in both cases, obviously, 826 00:49:49,160 --> 00:49:51,880 Speaker 1: given that this is an item that will explode, you 827 00:49:51,920 --> 00:49:54,680 Speaker 1: don't necessarily have to be as precise. It's not a 828 00:49:54,719 --> 00:49:56,919 Speaker 1: situation where you have to hit somebody in the head 829 00:49:56,920 --> 00:49:59,000 Speaker 1: with it or in the neck with it every time 830 00:49:59,040 --> 00:50:01,160 Speaker 1: for the weapon to be successful. Though I guess there 831 00:50:01,160 --> 00:50:03,560 Speaker 1: would be situations where you were trying to throw said 832 00:50:03,560 --> 00:50:08,640 Speaker 1: grenade into say a window or some sort of an 833 00:50:08,719 --> 00:50:09,919 Speaker 1: opening and a tank, etc. 834 00:50:10,840 --> 00:50:12,840 Speaker 2: Well, or like in other cases we've looked at to 835 00:50:12,960 --> 00:50:16,960 Speaker 2: compel behavior to drive people away from a particular location. 836 00:50:17,880 --> 00:50:21,600 Speaker 1: Yeah, I was thinking about Monty Python many months back, 837 00:50:21,640 --> 00:50:23,520 Speaker 1: and I of course thought of the Holy Hand Grenade 838 00:50:23,520 --> 00:50:26,840 Speaker 1: of Antioch, the magical weapon that is used against the 839 00:50:27,800 --> 00:50:31,520 Speaker 1: Killer Rabbit. And I remember looking around a little bit 840 00:50:32,520 --> 00:50:34,960 Speaker 1: just to see was there anything in use during the 841 00:50:35,000 --> 00:50:38,680 Speaker 1: general historic range that we're talking about here that would 842 00:50:38,719 --> 00:50:43,360 Speaker 1: have been like a grenade, And as I recall, there wasn't, really, 843 00:50:43,400 --> 00:50:47,600 Speaker 1: so I guess there is maybe a potential lag. There's 844 00:50:47,640 --> 00:50:51,400 Speaker 1: this kind of gap between the high age of stone 845 00:50:51,440 --> 00:50:54,480 Speaker 1: throwing and stick throwing as a viable weapon, and then 846 00:50:54,520 --> 00:51:00,799 Speaker 1: the emergence of explosives, which kind of reignites the need 847 00:51:00,840 --> 00:51:05,200 Speaker 1: to be able to throw precisely or at least with 848 00:51:05,320 --> 00:51:07,600 Speaker 1: some degree of precision. You don't want to throw a 849 00:51:07,640 --> 00:51:12,200 Speaker 1: hand grenade imprecisely, but we certainly see with hand grenades 850 00:51:12,239 --> 00:51:15,160 Speaker 1: that like the need for individuals to throw these things 851 00:51:15,200 --> 00:51:18,960 Speaker 1: becomes all the more important. I mean, you look at 852 00:51:19,000 --> 00:51:22,640 Speaker 1: images of say, modern soldiers training to throw hand grenades, 853 00:51:22,920 --> 00:51:26,680 Speaker 1: and there's a definite form to how you do it, 854 00:51:27,320 --> 00:51:31,040 Speaker 1: you know, like there's definite training in place, so precise 855 00:51:31,640 --> 00:51:36,000 Speaker 1: throwing of handheld objects remains a seemingly important part of 856 00:51:36,440 --> 00:51:38,040 Speaker 1: the modern military scenario. 857 00:51:38,680 --> 00:51:40,439 Speaker 2: You know, I didn't plan it like this, but it's 858 00:51:40,440 --> 00:51:44,879 Speaker 2: interesting how this series began as us wanting to look 859 00:51:44,880 --> 00:51:50,279 Speaker 2: at examples of non human animals throwing, and ultimately the 860 00:51:50,320 --> 00:51:53,279 Speaker 2: main thing that I'm taking away from it is the 861 00:51:53,360 --> 00:51:57,000 Speaker 2: special role of throwing in the development of human culture, 862 00:51:57,080 --> 00:51:58,040 Speaker 2: in human cognition. 863 00:51:59,080 --> 00:52:01,399 Speaker 1: Yeah, yeah, I surprised by it as well, because, yeah, 864 00:52:02,120 --> 00:52:04,960 Speaker 1: we started off with the octopus and now here we 865 00:52:05,040 --> 00:52:08,279 Speaker 1: are talking about soldiers with grenades. We have to keep 866 00:52:08,280 --> 00:52:11,200 Speaker 1: the grenades away from the octopuses. By the way, Yes, 867 00:52:12,080 --> 00:52:14,440 Speaker 1: I should also point out I didn't even get into 868 00:52:14,840 --> 00:52:19,200 Speaker 1: the use of sharpened throwing weapons, but obviously that's a 869 00:52:19,239 --> 00:52:21,880 Speaker 1: huge part of weapon culture throughout history as well. I 870 00:52:21,880 --> 00:52:26,240 Speaker 1: don't know. I guess it felt like one step manufacturing 871 00:52:26,320 --> 00:52:30,040 Speaker 1: or materially away from just throwing a stick or throwing 872 00:52:30,040 --> 00:52:31,960 Speaker 1: a rock, So I didn't get into that, But obviously 873 00:52:32,000 --> 00:52:35,799 Speaker 1: there's a lot one could additionally discuss involving hand thrown axes, 874 00:52:35,840 --> 00:52:40,239 Speaker 1: hand thrown darts and knives and so forth. So I 875 00:52:40,239 --> 00:52:43,520 Speaker 1: guess different aerodynamic properties come into play with at least 876 00:52:43,560 --> 00:52:47,080 Speaker 1: some of those weapon designs. All right, we're gonna go 877 00:52:47,080 --> 00:52:48,799 Speaker 1: ahead and end it there, but we'd love to hear 878 00:52:48,840 --> 00:52:54,520 Speaker 1: from everyone out there if you have thoughts, feedback, experience 879 00:52:55,000 --> 00:52:57,840 Speaker 1: on anything we've discussed here in this episode or the 880 00:52:57,840 --> 00:53:05,080 Speaker 1: previous episodes regarding animals throwing things, humans throwing things, the 881 00:53:05,520 --> 00:53:09,799 Speaker 1: role that being able to throw something may have in 882 00:53:09,880 --> 00:53:15,160 Speaker 1: the development of language, and also just the various weapons 883 00:53:15,160 --> 00:53:19,120 Speaker 1: cultures martial arts that have involved hand thrown objects. If 884 00:53:19,160 --> 00:53:21,280 Speaker 1: you have anything to add about any of that, please 885 00:53:21,320 --> 00:53:23,640 Speaker 1: write in we would love to hear from you.
