And 3 00:00:10,440 --> 00:00:12,320 Speaker 1: it's Saturday. Time to go into the vault for a 4 00:00:12,360 --> 00:00:15,280 Speaker 1: classic episode of the show. This one was originally called 5 00:00:15,400 --> 00:00:20,320 Speaker 1: Surfing Neander Tolls and it published on August nineteen. So 6 00:00:20,440 --> 00:00:26,479 Speaker 1: grab a board, the surf is up. Welcome to Stuff 7 00:00:26,480 --> 00:00:28,480 Speaker 1: to Blow Your Mind, a production of I Heart Radios 8 00:00:28,520 --> 00:00:37,160 Speaker 1: How Stuff Works. Hey, you welcome to Stuff to Blow 9 00:00:37,200 --> 00:00:40,240 Speaker 1: your Mind. My name is Robert Lamb and I'm Joe McCormick. 10 00:00:40,320 --> 00:00:42,400 Speaker 1: And before we turn the mics on, or actually after 11 00:00:42,400 --> 00:00:44,479 Speaker 1: we turned the mics on, but before we officially started 12 00:00:44,479 --> 00:00:46,760 Speaker 1: the episode, we were just talking about is there a 13 00:00:46,920 --> 00:00:50,680 Speaker 1: better eighties action movie than Point Break? Um? I mean, 14 00:00:50,840 --> 00:00:53,720 Speaker 1: arguably there there are some, definitely some action pictures that 15 00:00:53,880 --> 00:00:57,280 Speaker 1: I love more than Point Break, But Point Break has 16 00:00:57,360 --> 00:01:00,840 Speaker 1: a purity to it, you know, this like this, this 17 00:01:01,360 --> 00:01:06,160 Speaker 1: the weird nobility of this band of nomadic surfers who 18 00:01:06,160 --> 00:01:10,360 Speaker 1: are also bank robbers and uh and then the man 19 00:01:10,560 --> 00:01:13,480 Speaker 1: who is pursuing them, a man who must become a 20 00:01:13,520 --> 00:01:16,280 Speaker 1: surfer in order to catch surfers. Because isn't that it 21 00:01:16,400 --> 00:01:18,360 Speaker 1: that the old saying in order to catch a surfer, 22 00:01:18,400 --> 00:01:21,959 Speaker 1: you must become a surfer. Uh, something like that. Patrick 23 00:01:22,040 --> 00:01:23,920 Speaker 1: Swayze is the key to the movie. Oh and hey, 24 00:01:23,959 --> 00:01:25,640 Speaker 1: by the way, if you're out there, some kind of 25 00:01:25,680 --> 00:01:28,360 Speaker 1: pedants saying wait a minute point break didn't come out 26 00:01:28,360 --> 00:01:30,160 Speaker 1: in the nineteen eighties. How are you saying it's the 27 00:01:30,160 --> 00:01:33,399 Speaker 1: best eighties action movie? As we all know, Sinna in 28 00:01:33,480 --> 00:01:37,959 Speaker 1: the cinema world, the nineteen eighties lasted until Okay, yeah, 29 00:01:38,080 --> 00:01:41,039 Speaker 1: I think that's a solid argument. But yeah, this was. 30 00:01:41,319 --> 00:01:44,440 Speaker 1: This was some some really great sways in this film, 31 00:01:44,800 --> 00:01:48,560 Speaker 1: Like Swayzy just has such such a unique charisma that 32 00:01:49,080 --> 00:01:52,480 Speaker 1: he's it's it's like with the Rhodhouse. You know, he's 33 00:01:52,520 --> 00:01:55,440 Speaker 1: he's able to be just so serious in this role 34 00:01:55,840 --> 00:01:59,040 Speaker 1: and it's and you're you're laughing because it is ridiculous, 35 00:01:59,040 --> 00:02:03,040 Speaker 1: but at the same time you're totally buying into this presentation. 36 00:02:03,080 --> 00:02:06,680 Speaker 1: He's giving you absolutely the the deep seriousness and the 37 00:02:06,720 --> 00:02:10,640 Speaker 1: delivery of the lines like pain don't hurt, the fact 38 00:02:10,760 --> 00:02:13,400 Speaker 1: that he is is trying to commit to this character 39 00:02:13,440 --> 00:02:18,400 Speaker 1: who's like a philosopher bouncer. Yeah, in Roadhouse, but now, 40 00:02:18,440 --> 00:02:20,600 Speaker 1: I mean, essentially, I think he's playing the same character 41 00:02:20,760 --> 00:02:23,799 Speaker 1: in Point Break, and that in Roadhouse he's a philosopher bouncer. 42 00:02:24,080 --> 00:02:26,280 Speaker 1: In Point Break, he's the same character. He's now become 43 00:02:26,280 --> 00:02:31,440 Speaker 1: a philosopher surfer slash bank robber. Yeah, and and he's 44 00:02:31,480 --> 00:02:34,000 Speaker 1: he's tremendous. He just like he eats that they've seen 45 00:02:34,040 --> 00:02:36,320 Speaker 1: he's in point Point Break is a great example of 46 00:02:36,320 --> 00:02:39,880 Speaker 1: one of these eighties again, but it was the eighties. 47 00:02:40,360 --> 00:02:43,799 Speaker 1: Eighties action movies that is so silly in a way 48 00:02:43,880 --> 00:02:47,000 Speaker 1: that like, there are still action movies that have a 49 00:02:47,080 --> 00:02:50,919 Speaker 1: great spirit of silliness that aren't like these unpleasant, self 50 00:02:50,960 --> 00:02:53,800 Speaker 1: serious action movies. Uh well, you know, a good example 51 00:02:53,919 --> 00:02:56,000 Speaker 1: is like the later movies in the Fast and the 52 00:02:56,040 --> 00:02:58,680 Speaker 1: Furious franchise, which can be a lot of fun, but 53 00:02:58,840 --> 00:03:01,320 Speaker 1: they are they're in the joke like the rock is 54 00:03:01,360 --> 00:03:04,600 Speaker 1: winking at the camera. It's you know, it's played explicitly 55 00:03:04,960 --> 00:03:07,640 Speaker 1: for a kind of like wet laughter that like cars 56 00:03:07,680 --> 00:03:10,959 Speaker 1: can fly and all this, But that's not what's going 57 00:03:10,960 --> 00:03:13,200 Speaker 1: on in Point Break, Point Break, and and some of 58 00:03:13,200 --> 00:03:15,640 Speaker 1: the movies like it are just as silly as the 59 00:03:15,760 --> 00:03:19,000 Speaker 1: later Fast and the Furious movies, but they're not they're 60 00:03:19,000 --> 00:03:21,400 Speaker 1: not winking at you. They're not in on the joke. Instead, 61 00:03:21,400 --> 00:03:25,160 Speaker 1: they've got Patrick Swayzy, who's taken himself real seriously. I 62 00:03:25,160 --> 00:03:27,359 Speaker 1: wonder if part of that is that a film like 63 00:03:27,480 --> 00:03:31,040 Speaker 1: Point Break like building on the in a sense, even 64 00:03:31,040 --> 00:03:34,160 Speaker 1: though it's an eighties and so technically nineties film, it's 65 00:03:34,240 --> 00:03:37,880 Speaker 1: building on like the grittier uh, like a film heritage 66 00:03:37,880 --> 00:03:41,280 Speaker 1: of the nineteen seventies that preceded it, and where whereas 67 00:03:41,480 --> 00:03:45,640 Speaker 1: nineties films are are proceeding from the eighties films, uh 68 00:03:45,680 --> 00:03:47,800 Speaker 1: and so forth to where there's just like the initial 69 00:03:47,880 --> 00:03:51,600 Speaker 1: groundwork underneath something like The Fast and the Furious, it's 70 00:03:51,680 --> 00:03:54,640 Speaker 1: just that much sillier and that that and just further 71 00:03:54,720 --> 00:03:58,400 Speaker 1: removed from like nineteen seventies cinema. Wait a minute, why 72 00:03:58,440 --> 00:04:00,720 Speaker 1: are we talking about Point Break? Oh? Yeah, we're talking 73 00:04:00,720 --> 00:04:03,400 Speaker 1: about it because this episode is about surfing the inder Tals. 74 00:04:04,120 --> 00:04:06,680 Speaker 1: I mean, it's also not about surfing Neandertals, but it 75 00:04:06,760 --> 00:04:12,040 Speaker 1: is about Neanderthals. It's about surfer's ear and uh, surfing 76 00:04:12,040 --> 00:04:14,480 Speaker 1: the Andertals, the working title of Point Break that was 77 00:04:14,520 --> 00:04:18,640 Speaker 1: on the script. It It is exactly where my mind 78 00:04:18,640 --> 00:04:22,839 Speaker 1: went when I first read a very recent scientific paper 79 00:04:22,880 --> 00:04:25,479 Speaker 1: that came out about the under tolls and surfers here. 80 00:04:26,160 --> 00:04:28,080 Speaker 1: But but before we get into all that, um and 81 00:04:28,120 --> 00:04:32,719 Speaker 1: we may come back two point break. As we proceed again, 82 00:04:32,760 --> 00:04:34,760 Speaker 1: I want to be clear that this episode is not 83 00:04:34,960 --> 00:04:37,000 Speaker 1: really about surfing. It doesn't have that much to do 84 00:04:37,040 --> 00:04:38,680 Speaker 1: with surfing. But I do want to point out the 85 00:04:38,720 --> 00:04:42,800 Speaker 1: ancient origins of this aquatic practice we call surfing. What 86 00:04:42,960 --> 00:04:46,159 Speaker 1: surfing wasn't invented in the nineteen sixties, No, no, no. 87 00:04:46,760 --> 00:04:49,039 Speaker 1: And I was looking at a couple of sources on this, 88 00:04:49,400 --> 00:04:51,160 Speaker 1: but but one of the better ones that came across 89 00:04:51,360 --> 00:04:54,919 Speaker 1: um it was a book by Ben R. Finney and 90 00:04:55,040 --> 00:04:57,880 Speaker 1: James D. Houston called Surfing, A History of the Ancient 91 00:04:57,920 --> 00:05:01,640 Speaker 1: Hawaiian Sport and U pretty inscifle. They point out that 92 00:05:01,640 --> 00:05:04,600 Speaker 1: that all you need really to surf is a surfer 93 00:05:04,600 --> 00:05:08,599 Speaker 1: and a board and of course waves um or something 94 00:05:08,680 --> 00:05:10,440 Speaker 1: standing in for a board, such as a canoe, or 95 00:05:10,480 --> 00:05:12,960 Speaker 1: even the surfer's own body. I mean, you can body surf. 96 00:05:13,200 --> 00:05:16,800 Speaker 1: What You don't need a surfballa you don't need a 97 00:05:16,800 --> 00:05:20,360 Speaker 1: surf suit. Well, as we'll discuss, it can be very helpful, 98 00:05:20,880 --> 00:05:23,560 Speaker 1: especially in the colder waters. But you know, it's just 99 00:05:23,720 --> 00:05:26,400 Speaker 1: it's ultimately and I don't know. Have you ever surfed, Joe, 100 00:05:26,480 --> 00:05:32,560 Speaker 1: have you ever? No, I've I mean very limited water experience. 101 00:05:32,640 --> 00:05:35,680 Speaker 1: I've done like knee boarding, and that's I know, that's 102 00:05:35,680 --> 00:05:37,800 Speaker 1: not surfing. I'd say that's the closest to that. You've 103 00:05:37,880 --> 00:05:40,960 Speaker 1: You've gotten up on your knees on a surfboard, well, 104 00:05:40,960 --> 00:05:42,720 Speaker 1: not on a surfboard, on a knee board. I don't 105 00:05:42,720 --> 00:05:44,640 Speaker 1: know how different they are. I've gotten up on my 106 00:05:44,720 --> 00:05:46,680 Speaker 1: knees on a floating thing that was being towed behind 107 00:05:46,680 --> 00:05:52,200 Speaker 1: a boat. Okay, well a little. It's not close, but 108 00:05:52,200 --> 00:05:54,320 Speaker 1: but it's it's enough. We can we can build from here. 109 00:05:54,839 --> 00:05:58,039 Speaker 1: So I I am not a surfer, but I on 110 00:05:58,400 --> 00:06:01,159 Speaker 1: a trip to Whoa I, um, you know, like like 111 00:06:01,480 --> 00:06:05,240 Speaker 1: twenty years ago or something. Um, I was encouraged by 112 00:06:05,240 --> 00:06:07,720 Speaker 1: a friend to go out and try it. This friend 113 00:06:07,760 --> 00:06:10,200 Speaker 1: had surfed before. This is very helpful I find. If 114 00:06:10,240 --> 00:06:12,480 Speaker 1: you were going to try to surf, uh, certainly go 115 00:06:12,600 --> 00:06:14,839 Speaker 1: with someone who has at least done it once before, 116 00:06:15,240 --> 00:06:18,160 Speaker 1: but preverably somebody who who is more skilled than that. 117 00:06:18,640 --> 00:06:21,839 Speaker 1: But there is this kind of magical moment where you're 118 00:06:21,880 --> 00:06:24,760 Speaker 1: you're pushing the board, you're you're you're paddling and kicking. 119 00:06:24,960 --> 00:06:27,840 Speaker 1: You're just going as hard and as fast as you can. Uh, 120 00:06:27,920 --> 00:06:31,040 Speaker 1: and then it comes this this almost magical moment where 121 00:06:31,040 --> 00:06:34,880 Speaker 1: the wave catches the board and suddenly the waves propelling 122 00:06:34,920 --> 00:06:36,599 Speaker 1: the board. And this is the point where then you 123 00:06:36,640 --> 00:06:39,159 Speaker 1: can climb up on onto your knees on the board. 124 00:06:39,160 --> 00:06:41,520 Speaker 1: And then and once you you know, have your figure 125 00:06:41,520 --> 00:06:43,440 Speaker 1: out what you're doing, this is where you can rise 126 00:06:43,560 --> 00:06:46,039 Speaker 1: up on both of your feet on the board and 127 00:06:46,080 --> 00:06:50,600 Speaker 1: you can ride the surfboard like a surfer rides a surfboard. 128 00:06:50,960 --> 00:06:54,440 Speaker 1: And it sounds hard. I mean, it's it's it's one 129 00:06:54,440 --> 00:06:56,320 Speaker 1: of those things where I definitely would have given up 130 00:06:56,360 --> 00:06:58,760 Speaker 1: had I not been encouraged to keep doing it, you know, 131 00:06:58,920 --> 00:07:02,040 Speaker 1: to just keep doing it again once more. Let's go, 132 00:07:02,120 --> 00:07:04,120 Speaker 1: let's paddle back, and then paddle as hard and fast 133 00:07:04,120 --> 00:07:06,280 Speaker 1: as you can to try and catch this magical moment 134 00:07:06,279 --> 00:07:09,400 Speaker 1: when the when the board catches you. Um. Yeah, and 135 00:07:09,440 --> 00:07:12,240 Speaker 1: so like once so, all you need is aboard the 136 00:07:12,280 --> 00:07:15,960 Speaker 1: waves yourself and then, like the patients and or courage 137 00:07:16,000 --> 00:07:18,120 Speaker 1: to to reach that point where you can rise up 138 00:07:18,120 --> 00:07:20,200 Speaker 1: on the board and become comfortable enough doing so that 139 00:07:20,240 --> 00:07:23,400 Speaker 1: you can manipulate the bird board further. Okay, so surfing 140 00:07:23,480 --> 00:07:26,440 Speaker 1: was not invented by the beach boys in the mid 141 00:07:26,480 --> 00:07:30,120 Speaker 1: twentieth century. Where does surfing actually come from? Well, as 142 00:07:30,120 --> 00:07:32,360 Speaker 1: the authors at this point out how Hawaii is of 143 00:07:32,360 --> 00:07:35,480 Speaker 1: course strongly associated with surfing, and humans seem to have 144 00:07:35,520 --> 00:07:40,040 Speaker 1: first arrived at these far flung Polynesian islands by between 145 00:07:40,040 --> 00:07:43,600 Speaker 1: three hundred and four hundred CE. Now, long boards would 146 00:07:43,640 --> 00:07:46,640 Speaker 1: have developed over time, and the author's guess that Hawaiian 147 00:07:46,680 --> 00:07:50,960 Speaker 1: surfing is ultimately perhaps a thousand years old, Yet the 148 00:07:51,000 --> 00:07:54,600 Speaker 1: principles involved would have been known to Pacific islanders and 149 00:07:54,640 --> 00:07:57,720 Speaker 1: the first pioneers to enter the Pacific as far back 150 00:07:57,760 --> 00:08:01,240 Speaker 1: as two thousand b C. So, um, you know, it's 151 00:08:01,280 --> 00:08:03,960 Speaker 1: one of those again, it's one of those things where 152 00:08:04,000 --> 00:08:08,840 Speaker 1: the necessary technology uh, and and and ability. You know. 153 00:08:08,920 --> 00:08:11,760 Speaker 1: It's not something that where it did not exist before 154 00:08:11,840 --> 00:08:15,400 Speaker 1: thousand years ago, you know, conceivably uh, you know, these 155 00:08:15,480 --> 00:08:20,880 Speaker 1: more ancient cultures knew of the properties involved. So we 156 00:08:20,920 --> 00:08:23,600 Speaker 1: don't know for sure how far back it could go, right, 157 00:08:23,680 --> 00:08:26,360 Speaker 1: And there's also some debate whether a form of stand 158 00:08:26,400 --> 00:08:29,280 Speaker 1: up paddle boarding practiced by the pre Incan civilization in 159 00:08:29,320 --> 00:08:33,000 Speaker 1: Peru would have constituted surfing. Some two thousand years ago. 160 00:08:33,640 --> 00:08:36,520 Speaker 1: Of course, that's another thing you get into, you know, 161 00:08:36,559 --> 00:08:39,439 Speaker 1: discussions of the terminology. Is it truly surfing, is it's 162 00:08:39,480 --> 00:08:42,320 Speaker 1: something else? Are are the people on these paddle boards 163 00:08:42,360 --> 00:08:44,720 Speaker 1: ever reaching that point where the you know, the magic 164 00:08:44,880 --> 00:08:48,000 Speaker 1: of the wave takes over and propels them. But anyway, 165 00:08:48,000 --> 00:08:50,160 Speaker 1: I just I found it. It'll be useful I think 166 00:08:50,160 --> 00:08:52,400 Speaker 1: to just think of that as we proceed, uh. And 167 00:08:52,600 --> 00:08:54,720 Speaker 1: in order to also keep it connected to surfing in 168 00:08:54,760 --> 00:08:57,040 Speaker 1: some way, to think of of surfing as this thing 169 00:08:57,040 --> 00:08:59,880 Speaker 1: that is at least a thousand years old, maybe all 170 00:09:00,000 --> 00:09:03,320 Speaker 1: older and uh and ultimately, just based on the technology involved, 171 00:09:03,400 --> 00:09:07,520 Speaker 1: is not all that uh, you know, constrained to a 172 00:09:07,559 --> 00:09:11,439 Speaker 1: particular portion of human time. For all we know dinosaurs 173 00:09:11,440 --> 00:09:15,120 Speaker 1: for surfing, definitely none for the dinosaurs, well, no, the 174 00:09:15,160 --> 00:09:18,840 Speaker 1: dinosaurs were not surfing. But I mean, ultimately, to come 175 00:09:18,880 --> 00:09:20,400 Speaker 1: back to the title of the episode, when you start 176 00:09:20,520 --> 00:09:24,320 Speaker 1: wondering if Neanderthals surfed, there's absolutely no evidence that they did. 177 00:09:25,120 --> 00:09:28,679 Speaker 1: But when you start considering the technology involved, yes, somebody 178 00:09:28,679 --> 00:09:30,480 Speaker 1: could make a case for it, and it would be 179 00:09:31,000 --> 00:09:32,880 Speaker 1: you know, you wouldn't have be able to prove it 180 00:09:32,920 --> 00:09:36,320 Speaker 1: necessary that we wouldn't be able to disprove it. So 181 00:09:36,640 --> 00:09:38,679 Speaker 1: what we're going to be talking about though in this 182 00:09:38,720 --> 00:09:41,640 Speaker 1: episode is more a matter of what is known as 183 00:09:41,720 --> 00:09:45,400 Speaker 1: surfers ear. Okay, Now, I remember from when I was 184 00:09:45,440 --> 00:09:48,680 Speaker 1: a kid, people I knew getting swimmers ear, but that 185 00:09:48,800 --> 00:09:52,600 Speaker 1: was just like ear infections, right right, Swimmers ear is 186 00:09:52,600 --> 00:09:55,480 Speaker 1: is the different things. Bacterial infection of the outer ear 187 00:09:55,559 --> 00:09:59,160 Speaker 1: often caused by trap water, So water or debris gets 188 00:09:59,160 --> 00:10:01,479 Speaker 1: trapped in the ear and it can cause an infection 189 00:10:02,000 --> 00:10:05,319 Speaker 1: and uh and depending on like the state and condition 190 00:10:05,360 --> 00:10:08,520 Speaker 1: of your your ear canals. Uh, some people are more 191 00:10:09,240 --> 00:10:11,800 Speaker 1: uh you know, have have more tendants, more greater tendency 192 00:10:11,840 --> 00:10:14,600 Speaker 1: to uh to get swimmers eer than other people. I 193 00:10:14,640 --> 00:10:17,920 Speaker 1: remember people with swimmers ere being treated by just getting 194 00:10:17,960 --> 00:10:20,839 Speaker 1: like ethyl alcohol pulled in there or maybe I don't 195 00:10:20,880 --> 00:10:23,440 Speaker 1: know what kind of some kind of alcohol alcohol uh 196 00:10:23,559 --> 00:10:26,000 Speaker 1: poured in their ear. Yeah, there's just a stest standard 197 00:10:26,080 --> 00:10:30,040 Speaker 1: swimmers ear um droplets you can get. I use some 198 00:10:30,200 --> 00:10:34,000 Speaker 1: like just the other day because I swim fairly regularly. 199 00:10:34,520 --> 00:10:37,320 Speaker 1: But uh. But but then also not to be confused 200 00:10:37,360 --> 00:10:38,840 Speaker 1: with the drops you would get for a full blown 201 00:10:38,840 --> 00:10:42,439 Speaker 1: ear infection. Like this is where yeah, everything is actually 202 00:10:42,480 --> 00:10:44,959 Speaker 1: getting like more and more painful in your ear, and 203 00:10:45,000 --> 00:10:49,000 Speaker 1: that may require uh, some more advanced drops, but that's 204 00:10:49,080 --> 00:10:50,840 Speaker 1: not really what we're talking about here. What we're talking 205 00:10:50,840 --> 00:10:55,360 Speaker 1: about here is exostosis of the external auditory canal or 206 00:10:55,440 --> 00:11:00,240 Speaker 1: external auditory exostosis or E a E also known as 207 00:11:00,440 --> 00:11:03,600 Speaker 1: surfers here and then the game. Yeah, and it's it's 208 00:11:03,600 --> 00:11:06,760 Speaker 1: a condition. It's a condition that affects both modern humans 209 00:11:06,920 --> 00:11:10,920 Speaker 1: and our our prehistoric ancestors. So what is E a E. Well, 210 00:11:11,000 --> 00:11:15,280 Speaker 1: these are dense bony growths that that that grow that 211 00:11:15,400 --> 00:11:20,559 Speaker 1: slowly extend into the auditory ear canal. Whoa bony growths 212 00:11:20,559 --> 00:11:23,840 Speaker 1: in the ear canal? Now, please reassure me, Robert that 213 00:11:23,880 --> 00:11:26,320 Speaker 1: these growths are not like spiny you know. No, No, 214 00:11:26,640 --> 00:11:30,440 Speaker 1: these are rounded growths um that you know. Basically, if 215 00:11:30,440 --> 00:11:32,000 Speaker 1: you look at it, if you look at an image 216 00:11:32,040 --> 00:11:35,080 Speaker 1: of this, it looks like they're bony growths on you know, 217 00:11:35,280 --> 00:11:38,199 Speaker 1: underneath the skin on either side that are like that, 218 00:11:38,280 --> 00:11:40,920 Speaker 1: are that are pushing in, causing kind of a cave in, 219 00:11:41,880 --> 00:11:45,160 Speaker 1: gradual cave in of the auditory canal. That still doesn't 220 00:11:45,200 --> 00:11:48,800 Speaker 1: sound good. So the question is what causes them? Well, 221 00:11:48,920 --> 00:11:52,320 Speaker 1: this is where it gets weird. It is, uh, we 222 00:11:52,440 --> 00:11:54,800 Speaker 1: basically still have a lot of questions about surfer's ear, 223 00:11:54,880 --> 00:11:59,720 Speaker 1: But the widely accepted hypothesis is the is the aquatic 224 00:11:59,760 --> 00:12:01,760 Speaker 1: hype ofthesis, and that is that it is caused by 225 00:12:01,840 --> 00:12:05,920 Speaker 1: repeated exposure to cold water or or in some cases 226 00:12:06,000 --> 00:12:10,320 Speaker 1: cold wind, but especially cold water. And it's typically encountered 227 00:12:10,320 --> 00:12:14,319 Speaker 1: in cold watered in cold water foraging among traditional and 228 00:12:14,360 --> 00:12:18,960 Speaker 1: ancient peoples, as well as among cold water sports practice 229 00:12:19,000 --> 00:12:23,360 Speaker 1: today such as surfing. Coming back to the question of 230 00:12:23,400 --> 00:12:25,680 Speaker 1: what is required for surfing, and you asked about body 231 00:12:25,760 --> 00:12:29,360 Speaker 1: suits and wet suits or dry suits, and uh, you know, 232 00:12:29,440 --> 00:12:31,320 Speaker 1: and and a part of this is has to do 233 00:12:31,360 --> 00:12:33,240 Speaker 1: with the fact that, in addition to having to deal 234 00:12:33,280 --> 00:12:36,360 Speaker 1: with you know, potentially being scraped up against things you 235 00:12:36,360 --> 00:12:39,800 Speaker 1: don't want your body scraped against, you're often also surfing 236 00:12:39,880 --> 00:12:43,240 Speaker 1: in colder environments and uh, and you want to protect 237 00:12:43,280 --> 00:12:47,880 Speaker 1: your body from the cold. But the cold water is 238 00:12:47,880 --> 00:12:50,839 Speaker 1: is also an irritant to the inner ear, and uh, 239 00:12:50,880 --> 00:12:53,520 Speaker 1: and it is the most commonly observed irritant that leads 240 00:12:53,559 --> 00:12:57,880 Speaker 1: to surfers ear, and repeated irritation leads to this growth. Now, 241 00:12:57,880 --> 00:12:59,880 Speaker 1: wait a minute, it sounded like you were alluding to 242 00:13:00,000 --> 00:13:05,680 Speaker 1: they're being potential, multiple potential explanations. Right, well, this is 243 00:13:05,800 --> 00:13:08,440 Speaker 1: I mean, well this is the primary explanation, um, and 244 00:13:08,640 --> 00:13:13,640 Speaker 1: I did not encounter another explanation that that was really presented. Basically, 245 00:13:13,640 --> 00:13:16,400 Speaker 1: it's just there are some mysteries remain about exactly how 246 00:13:16,440 --> 00:13:21,440 Speaker 1: it occurs. Uh. And Uh, anybody that's discussing surfers here 247 00:13:21,480 --> 00:13:25,480 Speaker 1: like is sticking to the aquatic hypothesis here. Uh, and 248 00:13:25,480 --> 00:13:28,000 Speaker 1: then certainly the evidence bears it out that it's I mean, 249 00:13:28,040 --> 00:13:30,880 Speaker 1: you look at at where surfers here occurs, and it 250 00:13:30,920 --> 00:13:33,880 Speaker 1: occurs in the ears of individuals who are engaging in 251 00:13:33,920 --> 00:13:36,840 Speaker 1: a lot of cold water activity, be it foraging, you know, 252 00:13:37,120 --> 00:13:41,640 Speaker 1: pearl diving that sort of thing, or surfing. But you know, 253 00:13:41,679 --> 00:13:45,800 Speaker 1: other forms of irritation can can can technically cause it, uh, 254 00:13:46,000 --> 00:13:48,360 Speaker 1: because it's just gonna result in tissue inflammation in the 255 00:13:48,400 --> 00:13:50,360 Speaker 1: inner ear. Now, so that's going to happen after just 256 00:13:50,480 --> 00:13:52,840 Speaker 1: like you have a couple of bad days in cold 257 00:13:52,880 --> 00:13:55,439 Speaker 1: water and you get these growths. No, no, no, it's uh, 258 00:13:55,480 --> 00:13:58,600 Speaker 1: this is something that's going to develop over the years. 259 00:13:58,880 --> 00:14:02,280 Speaker 1: So typically you see it manifest in a person during 260 00:14:02,360 --> 00:14:04,920 Speaker 1: their like their mid to late thirties or possibly in 261 00:14:04,960 --> 00:14:08,679 Speaker 1: their forties, lining up with the timeline of their exposure 262 00:14:08,720 --> 00:14:11,760 Speaker 1: to the irritation. It could potentially occur earlier though, But 263 00:14:11,840 --> 00:14:14,160 Speaker 1: like this is like when you think about like someone's 264 00:14:14,200 --> 00:14:17,240 Speaker 1: prime surfing years and at what point they've been surfing 265 00:14:17,320 --> 00:14:20,480 Speaker 1: for uh, you know, for say twenty years, that sort 266 00:14:20,520 --> 00:14:23,480 Speaker 1: of thing. Uh, it's gonna line up with this. So 267 00:14:23,520 --> 00:14:25,520 Speaker 1: you're more likely to see it in people who spend 268 00:14:25,560 --> 00:14:27,600 Speaker 1: a lot of time in the water over a long 269 00:14:27,800 --> 00:14:30,280 Speaker 1: period of their lives. Right, Yeah, they're spending a lot 270 00:14:30,320 --> 00:14:32,800 Speaker 1: of time in cold water, Like they're going surfing a 271 00:14:32,840 --> 00:14:35,440 Speaker 1: lot where they're going pearl diving a lot with with 272 00:14:35,520 --> 00:14:38,360 Speaker 1: a uh, you know, a fair degree of regularity. Well, 273 00:14:38,400 --> 00:14:41,720 Speaker 1: so it would seem like having bony growths protruding into 274 00:14:41,760 --> 00:14:44,440 Speaker 1: your ear canal would not be a good thing. Right, 275 00:14:44,520 --> 00:14:46,880 Speaker 1: So for for the for the longest, it's not really 276 00:14:47,000 --> 00:14:50,080 Speaker 1: an issue, but you know, it'll reach the point where 277 00:14:50,360 --> 00:14:54,400 Speaker 1: you'll have potential complications from your essentially you're closing ear canals. 278 00:14:54,920 --> 00:14:59,280 Speaker 1: That includes decreased hearing capability uh and increased likelihood of 279 00:14:59,320 --> 00:15:02,200 Speaker 1: blockage in an infection due to trapped ear wax or debris. 280 00:15:02,800 --> 00:15:04,880 Speaker 1: And you know, you see generally you're looking at a 281 00:15:05,120 --> 00:15:08,360 Speaker 1: five to eight millimeter diameter ear canal, but this can 282 00:15:08,400 --> 00:15:13,080 Speaker 1: be narrowed to almost total blockage over time by surfers here. 283 00:15:13,280 --> 00:15:17,440 Speaker 1: Am I imagining that there's kind of a cultural stereotype 284 00:15:17,480 --> 00:15:21,640 Speaker 1: where the you know, the the archetype, the surfer dude, 285 00:15:21,840 --> 00:15:25,880 Speaker 1: the surfer person is saying like, what what did you say? 286 00:15:25,960 --> 00:15:29,080 Speaker 1: A lot? Is that? Is that just my imagination or 287 00:15:29,240 --> 00:15:32,240 Speaker 1: does that exist as part of the stereotype? Um, I mean, 288 00:15:32,280 --> 00:15:36,320 Speaker 1: there's certain certainly a crossover between like the surfer stereotype 289 00:15:36,320 --> 00:15:38,760 Speaker 1: and sort of the the dude and sort of hippie 290 00:15:38,960 --> 00:15:43,520 Speaker 1: freewheeling stereotype. I don't know if lack of hearing is 291 00:15:43,520 --> 00:15:45,200 Speaker 1: really part of it, but it would make sense that 292 00:15:45,320 --> 00:15:47,680 Speaker 1: that it would be right because based on what we're 293 00:15:47,680 --> 00:15:49,640 Speaker 1: discussing here, I mean, this is this is where you're 294 00:15:49,640 --> 00:15:52,800 Speaker 1: going to see some potential hearing loss due to exposure 295 00:15:52,840 --> 00:15:55,800 Speaker 1: to the cold water. Now. An important thing to stress, though, 296 00:15:55,880 --> 00:15:58,600 Speaker 1: is that we only discovered surfers here in the last 297 00:15:58,640 --> 00:16:01,920 Speaker 1: century or so. I believe the first report on it 298 00:16:02,000 --> 00:16:06,560 Speaker 1: was a German paper by Welker h Uber in eighteen 299 00:16:06,600 --> 00:16:10,520 Speaker 1: sixty four. And uh, and so you know, we haven't 300 00:16:10,520 --> 00:16:13,080 Speaker 1: had that long to like really study it and figure 301 00:16:13,080 --> 00:16:15,440 Speaker 1: out what's what the deal is with it, or even 302 00:16:15,440 --> 00:16:17,040 Speaker 1: to figure out how in know ways to treat it 303 00:16:17,800 --> 00:16:20,280 Speaker 1: or how to to prevent it. But the most obvious 304 00:16:20,280 --> 00:16:22,640 Speaker 1: ways to prevent it are of course to avoid regular 305 00:16:22,640 --> 00:16:27,160 Speaker 1: cold water activities um which may not be an option 306 00:16:27,360 --> 00:16:30,440 Speaker 1: or or desirable for you if if you're really into 307 00:16:30,440 --> 00:16:33,000 Speaker 1: surfing or you depend on some sort of cold water foraging. 308 00:16:33,520 --> 00:16:37,200 Speaker 1: But I've read that cold water surfers are six more 309 00:16:37,280 --> 00:16:41,360 Speaker 1: likely to experience it than warm water surfers and sounds 310 00:16:41,400 --> 00:16:45,400 Speaker 1: like a significant effect. Now, you can also wear varying 311 00:16:45,400 --> 00:16:48,760 Speaker 1: forms of ear protection that will help, ranging from special 312 00:16:48,800 --> 00:16:51,560 Speaker 1: plugs to cat special caps to go over your head 313 00:16:51,600 --> 00:16:54,520 Speaker 1: in your ear, to certain varieties of wet suits. But 314 00:16:54,640 --> 00:16:58,280 Speaker 1: if you reach the point where where the bony protrusions 315 00:16:58,360 --> 00:17:02,200 Speaker 1: have grown to the point that it's an issue, doctors 316 00:17:02,200 --> 00:17:06,240 Speaker 1: can also remove the expotosis with a surgical drill. There 317 00:17:06,240 --> 00:17:09,600 Speaker 1: I think two different procedures, two different ways of going 318 00:17:09,640 --> 00:17:13,520 Speaker 1: in there and drilling back the bone the bony growths. 319 00:17:13,600 --> 00:17:15,600 Speaker 1: And the good news is that if if you have 320 00:17:15,680 --> 00:17:18,359 Speaker 1: this done, you'll probably you really probably only have to 321 00:17:18,359 --> 00:17:21,640 Speaker 1: do it once because generally, given the timeline of them 322 00:17:21,640 --> 00:17:24,720 Speaker 1: growing back. They can grow back, but you probably won't 323 00:17:24,720 --> 00:17:27,200 Speaker 1: reach that second point where you'll need to have them removed. 324 00:17:27,240 --> 00:17:28,760 Speaker 1: All right, looks like we need to take a break. 325 00:17:28,760 --> 00:17:30,840 Speaker 1: But when we come back, we will ask the question 326 00:17:31,119 --> 00:17:36,920 Speaker 1: of why these spurs and the ears? All right, we're back, 327 00:17:36,960 --> 00:17:39,600 Speaker 1: all right. So we've been talking about surfers ere or 328 00:17:39,720 --> 00:17:44,760 Speaker 1: the idea of external auditory exostoses or e a E. 329 00:17:44,920 --> 00:17:48,120 Speaker 1: And these are these bone like protrusions into the ear 330 00:17:48,119 --> 00:17:50,800 Speaker 1: canal that seem to pop up in people who spend 331 00:17:50,800 --> 00:17:53,400 Speaker 1: a lot of their lives in cold water. If you're 332 00:17:53,440 --> 00:17:57,040 Speaker 1: constantly irritating the ear canal with cold water, these things 333 00:17:57,160 --> 00:18:00,359 Speaker 1: are likely to pop up. Now, I guess we haven't 334 00:18:00,840 --> 00:18:05,280 Speaker 1: addressed yet why they occur. Well, if you think back 335 00:18:05,320 --> 00:18:09,040 Speaker 1: to the Bible, you have Cane and Able and uh 336 00:18:09,280 --> 00:18:12,520 Speaker 1: Able you know, was was really into stand on the land. 337 00:18:12,600 --> 00:18:15,680 Speaker 1: Cane was a big surfer, So God punish it now, Um, 338 00:18:15,800 --> 00:18:18,040 Speaker 1: that has nothing to do with that. Now. Now, this 339 00:18:18,119 --> 00:18:20,119 Speaker 1: is another area where it's there's still a lot of 340 00:18:20,160 --> 00:18:23,119 Speaker 1: open questions about it. Now, so some argue that it's 341 00:18:23,200 --> 00:18:26,960 Speaker 1: essentially like bone spurs, you know, which these occur either 342 00:18:27,040 --> 00:18:29,960 Speaker 1: due to these occur you know, due to constant irritation 343 00:18:30,119 --> 00:18:33,200 Speaker 1: or stress generally in the feet where you have these 344 00:18:33,240 --> 00:18:36,720 Speaker 1: bony um you know, protrusions that are forming in the 345 00:18:36,760 --> 00:18:39,359 Speaker 1: foot could be quite painful. So one idea is that 346 00:18:39,440 --> 00:18:43,879 Speaker 1: it's basically that irritation leading to growth, leading to symptoms. 347 00:18:44,280 --> 00:18:46,840 Speaker 1: And there's not a lot else beyond that in terms 348 00:18:46,840 --> 00:18:49,639 Speaker 1: of why, like what is the reason, you know, because 349 00:18:49,640 --> 00:18:52,000 Speaker 1: it's like asking what is what is the reason for 350 00:18:52,040 --> 00:18:54,919 Speaker 1: bone spurs? What is you know, what are the reason 351 00:18:54,960 --> 00:18:58,600 Speaker 1: for for various ailments that afflict us due to the 352 00:18:58,600 --> 00:19:01,320 Speaker 1: things that we insist on do ing due to our 353 00:19:02,119 --> 00:19:05,640 Speaker 1: you know, our our human desire to to ride waves 354 00:19:05,720 --> 00:19:09,200 Speaker 1: or climb mountains to ridiculous heights, that sort of thing. 355 00:19:10,280 --> 00:19:13,560 Speaker 1: But there is one area we will see an argument 356 00:19:13,880 --> 00:19:17,520 Speaker 1: for a purpose behind all that. Unfortunately it's in aquatic 357 00:19:17,600 --> 00:19:21,520 Speaker 1: eight theory. Oh yeah, So aquatic ape theory has come 358 00:19:21,600 --> 00:19:23,960 Speaker 1: up on the show before, and I think we've talked 359 00:19:23,960 --> 00:19:27,360 Speaker 1: about how this is one of those theories that's like 360 00:19:27,480 --> 00:19:32,000 Speaker 1: that's sticky. It's sticky beyond its explanatory power, and it's 361 00:19:32,040 --> 00:19:36,520 Speaker 1: hard to know exactly why some some hypotheses are like this, 362 00:19:36,600 --> 00:19:38,760 Speaker 1: but I think it tends to be the ones that 363 00:19:38,840 --> 00:19:43,320 Speaker 1: are just the most uh, that offered the most totalizing 364 00:19:43,440 --> 00:19:48,240 Speaker 1: explanation for the most phenomena through the most interesting image, 365 00:19:48,600 --> 00:19:52,800 Speaker 1: and it does that. It but it is also widely 366 00:19:52,880 --> 00:19:55,960 Speaker 1: rejected by science. And we can talk about some reasons 367 00:19:55,960 --> 00:19:58,119 Speaker 1: for that in a minute. Yeah, but it does continue 368 00:19:58,160 --> 00:19:59,639 Speaker 1: to come up, and you know, in fact, it was 369 00:19:59,760 --> 00:20:02,560 Speaker 1: it was recently brought up and by none other than 370 00:20:02,640 --> 00:20:06,960 Speaker 1: Sir David Attenborough himself. He apparently on a BBC four 371 00:20:07,600 --> 00:20:10,800 Speaker 1: um series he talked about it and he there's something 372 00:20:10,800 --> 00:20:14,040 Speaker 1: that criticized him for you know, bringing up, you know, 373 00:20:14,080 --> 00:20:17,760 Speaker 1: a redundant scientific theory. Well, I'm not gonna slam I mean, 374 00:20:17,880 --> 00:20:20,480 Speaker 1: you know, we talk about theories that are not accepted 375 00:20:20,560 --> 00:20:23,840 Speaker 1: because you know, it's okay to talk about things. I agree, Yeah, 376 00:20:23,960 --> 00:20:26,240 Speaker 1: you don't have to think something is correct to talk 377 00:20:26,280 --> 00:20:28,000 Speaker 1: about it. But it sounds like he was sort of 378 00:20:28,119 --> 00:20:31,879 Speaker 1: advocating it. Well, I mean, he has a history of 379 00:20:31,880 --> 00:20:33,880 Speaker 1: being interested in it. I read that he also organized 380 00:20:33,880 --> 00:20:37,320 Speaker 1: the symposium on the topic back in But you know, 381 00:20:37,320 --> 00:20:41,119 Speaker 1: it's like you said, we discuss theories and hypotheses on 382 00:20:41,160 --> 00:20:44,160 Speaker 1: this show that that are you know, sometimes definitely under 383 00:20:44,160 --> 00:20:48,080 Speaker 1: the category of of rejected or unprovable. Uh. And I 384 00:20:48,080 --> 00:20:51,560 Speaker 1: think my my opinion is that it is okay to 385 00:20:51,560 --> 00:20:54,840 Speaker 1: discuss these It's informative to it, and to discuss these ideas, 386 00:20:55,280 --> 00:20:57,080 Speaker 1: you know, as long as you're approaching them with the 387 00:20:57,160 --> 00:20:59,960 Speaker 1: right attitude and you're not like you know, you're not seeking, 388 00:21:00,760 --> 00:21:04,239 Speaker 1: uh to to prove them. You know, in in your 389 00:21:04,280 --> 00:21:07,119 Speaker 1: discussion of the of of of what is unprovable, right, 390 00:21:07,160 --> 00:21:11,880 Speaker 1: you're not becoming an evangelist for something based on bad evidence. Uh. Now, 391 00:21:11,960 --> 00:21:14,679 Speaker 1: So for a brief refresh, in case you don't recall 392 00:21:15,040 --> 00:21:16,840 Speaker 1: us talking about this theory in the past, the short 393 00:21:16,920 --> 00:21:19,720 Speaker 1: version is I think that the original idea was that 394 00:21:19,800 --> 00:21:24,280 Speaker 1: in nineteen sixty a marine biologist named Alistair Hardy proposed 395 00:21:24,480 --> 00:21:28,919 Speaker 1: this idea that we had an aquatic primate ancestor maybe 396 00:21:28,960 --> 00:21:32,800 Speaker 1: four to seven million years ago. And he proposed this 397 00:21:32,880 --> 00:21:35,080 Speaker 1: in this article a New Scientist. I think he also 398 00:21:35,119 --> 00:21:37,399 Speaker 1: gave a big talk about this. I think the idea 399 00:21:37,440 --> 00:21:41,480 Speaker 1: is that us having a an aquatic or semi aquatic 400 00:21:41,520 --> 00:21:47,000 Speaker 1: primate ancestor could explain many interesting morphological features of humans 401 00:21:47,040 --> 00:21:50,400 Speaker 1: that distinguish us from our closest relatives like the other 402 00:21:50,480 --> 00:21:52,639 Speaker 1: great apes. And there are a lot of examples of this, 403 00:21:52,760 --> 00:21:55,320 Speaker 1: like why do we have less body hair than the 404 00:21:55,359 --> 00:21:57,280 Speaker 1: other great apes? Why do we have this, you know, 405 00:21:57,320 --> 00:22:00,480 Speaker 1: smoother skin, And his idea was, well, maybe we lost 406 00:22:00,560 --> 00:22:03,480 Speaker 1: body hair and got smooth skin to streamline us for 407 00:22:03,520 --> 00:22:07,560 Speaker 1: swimming to reduce drag in the water. Um, why do 408 00:22:07,600 --> 00:22:11,080 Speaker 1: we have a thicker layer of subcutaneous fat uh than 409 00:22:11,160 --> 00:22:12,920 Speaker 1: some of the other than I think all the other 410 00:22:12,960 --> 00:22:15,480 Speaker 1: great apes. And his idea here is, well, maybe that's 411 00:22:15,520 --> 00:22:17,719 Speaker 1: like what we see in marine mammals that they use 412 00:22:17,760 --> 00:22:20,600 Speaker 1: for water insulation to help keep their bodies warm. Why 413 00:22:20,600 --> 00:22:23,320 Speaker 1: do we stand upright instead of walking on all fours? 414 00:22:23,400 --> 00:22:25,439 Speaker 1: The ideas well, maybe we had to wade in the 415 00:22:25,520 --> 00:22:28,639 Speaker 1: shallows and that got us standing up. And while it 416 00:22:28,720 --> 00:22:30,879 Speaker 1: is an interesting idea, and I think you know Hardy 417 00:22:30,920 --> 00:22:32,760 Speaker 1: it was it was clever for Hardy to come up 418 00:22:32,800 --> 00:22:36,359 Speaker 1: with this. I think we now have better explanations for 419 00:22:36,440 --> 00:22:39,159 Speaker 1: a lot of these interesting differences between humans and the 420 00:22:39,200 --> 00:22:43,600 Speaker 1: other great apes. And there's also no direct physical evidence 421 00:22:43,680 --> 00:22:46,160 Speaker 1: for the aquatic ape theory. But to bring it back 422 00:22:46,160 --> 00:22:49,440 Speaker 1: to the context here is this You're saying that some 423 00:22:49,640 --> 00:22:52,919 Speaker 1: enthusiasts of the aquatic ape theory would believe that our 424 00:22:53,000 --> 00:22:55,960 Speaker 1: ear canals or features of our ear canals would seem 425 00:22:56,040 --> 00:22:59,400 Speaker 1: to fit in with that list of supposed aquatic adaptations. Yeah, 426 00:22:59,480 --> 00:23:04,760 Speaker 1: I've ad e a positioned as possible evidence. You know 427 00:23:04,920 --> 00:23:07,440 Speaker 1: that it's a narrowing of the ear canals and keeping 428 00:23:07,440 --> 00:23:10,440 Speaker 1: with the narrowing of ear canals and aquatic mammals. It's 429 00:23:10,440 --> 00:23:13,280 Speaker 1: true enough the ear canals and toothed whales are narrow 430 00:23:13,359 --> 00:23:16,359 Speaker 1: and clogged with debris and wax. In bleeen whale ear 431 00:23:16,440 --> 00:23:20,080 Speaker 1: canals are plugged with a waxy cap. Now you know 432 00:23:20,080 --> 00:23:23,000 Speaker 1: they're obvious problems with this because it's not like, you know, 433 00:23:23,000 --> 00:23:26,200 Speaker 1: there's not some sort of Lamarchian scenario going on here 434 00:23:26,320 --> 00:23:30,000 Speaker 1: where surfers starts surfing and then their ears mutate into 435 00:23:30,080 --> 00:23:33,520 Speaker 1: into weird forms. It's not like the children of surfers 436 00:23:33,880 --> 00:23:39,160 Speaker 1: have have permanently plugged ear holes or anything. But maybe 437 00:23:39,200 --> 00:23:42,880 Speaker 1: the idea would be that we evolved the the adaptation 438 00:23:42,960 --> 00:23:46,480 Speaker 1: that gives our bodies the capability to adapt to repeated 439 00:23:46,480 --> 00:23:50,360 Speaker 1: water explight or or we would have developed the genetic 440 00:23:50,359 --> 00:23:55,320 Speaker 1: predisposition for for surfers here, and we do have a 441 00:23:55,359 --> 00:23:59,960 Speaker 1: genetic predisposition for surfers here. Uh that that's that seems 442 00:24:00,000 --> 00:24:04,160 Speaker 1: to be the case. But um, I think it's it's 443 00:24:04,160 --> 00:24:07,640 Speaker 1: a stretch to tie it in with this uh largely 444 00:24:07,680 --> 00:24:11,040 Speaker 1: refuted theory. Yeah, well, I mean I want to say 445 00:24:11,080 --> 00:24:14,000 Speaker 1: again not that we accept the theory or would advocate it, 446 00:24:14,040 --> 00:24:16,480 Speaker 1: but in the defense of this theory, I mean, it 447 00:24:16,640 --> 00:24:21,240 Speaker 1: is interesting to consider, and there's nothing inherently implausible about 448 00:24:21,320 --> 00:24:25,560 Speaker 1: the situation it imagines, nor nor insidious. It's not like 449 00:24:25,600 --> 00:24:29,080 Speaker 1: an anti science theory, right right, right, it's just so 450 00:24:29,400 --> 00:24:34,159 Speaker 1: there's nothing implausible about like prehistoric primates and migrating to 451 00:24:34,200 --> 00:24:39,000 Speaker 1: a partially aquatic lifestyle and gaining biological adaptations in the process. 452 00:24:39,359 --> 00:24:41,760 Speaker 1: It happened with other mammals, right, So it's not hard 453 00:24:41,800 --> 00:24:44,560 Speaker 1: to believe that a similar thing could have in principle 454 00:24:44,680 --> 00:24:47,880 Speaker 1: happened with primates. But the question is, just is that 455 00:24:47,920 --> 00:24:50,480 Speaker 1: what the evidence we have today's supports, And I think 456 00:24:50,600 --> 00:24:53,159 Speaker 1: most experts, for good reasons, think the answer is no. 457 00:24:54,240 --> 00:24:57,000 Speaker 1: M Most experts today believe the evidence for humans having 458 00:24:57,040 --> 00:25:00,400 Speaker 1: an aquatic ape ancestor doesn't hold up very well. Again, 459 00:25:00,440 --> 00:25:03,120 Speaker 1: there's zero direct evidence of it, so we don't have 460 00:25:03,240 --> 00:25:06,720 Speaker 1: like remains of an aquatic ancestor that just doesn't exist. 461 00:25:07,520 --> 00:25:10,600 Speaker 1: So you're you're having to hypothesize a sort of like 462 00:25:10,760 --> 00:25:13,880 Speaker 1: lost period that we haven't found direct evidence of yet, 463 00:25:13,920 --> 00:25:18,800 Speaker 1: but just reason backwards from traits that exist later. But 464 00:25:18,840 --> 00:25:21,320 Speaker 1: there's a basic question here. I can't I came across 465 00:25:21,400 --> 00:25:24,879 Speaker 1: this on from the writings of some paleo anthropologists, so 466 00:25:24,920 --> 00:25:28,760 Speaker 1: I'm sorry now I'm forgetting the the person's name. But 467 00:25:29,119 --> 00:25:32,760 Speaker 1: here here's a basic answer. If all these traits that 468 00:25:33,160 --> 00:25:35,960 Speaker 1: they're trying to explain through the aquatic ape theory were 469 00:25:36,000 --> 00:25:39,639 Speaker 1: acquired through an aquatic lifestyle that happened maybe four to 470 00:25:39,720 --> 00:25:42,840 Speaker 1: seven million years ago, why were all the aquatic traits 471 00:25:43,000 --> 00:25:47,520 Speaker 1: retained for millions of years after our ancestors supposedly moved 472 00:25:47,520 --> 00:25:50,320 Speaker 1: back to dry land. You would you would expect like 473 00:25:50,840 --> 00:25:53,520 Speaker 1: then the these traits would be lost because now they'd 474 00:25:53,520 --> 00:25:56,960 Speaker 1: be vestigial. We'd grow all that lovely hair back. Yeah, 475 00:25:57,400 --> 00:26:00,200 Speaker 1: unless you pose it like, well, actually, it turned out 476 00:26:00,240 --> 00:26:02,600 Speaker 1: once you moved back on the land, there was a 477 00:26:02,600 --> 00:26:06,199 Speaker 1: good reason for retaining that trait. Now, now it stayed 478 00:26:06,240 --> 00:26:09,480 Speaker 1: because it served some other survival purpose. But then you 479 00:26:09,480 --> 00:26:13,040 Speaker 1: could just short circuit the aquatic ape situation and say, well, 480 00:26:13,080 --> 00:26:15,600 Speaker 1: maybe we just got those traits because it served some 481 00:26:15,640 --> 00:26:19,040 Speaker 1: other purpose. So right, like like coming back to the 482 00:26:19,040 --> 00:26:21,040 Speaker 1: the hair theory of like the less hair you have, 483 00:26:21,080 --> 00:26:23,880 Speaker 1: the more you're able to show off that parasite free skin. Right, 484 00:26:23,960 --> 00:26:25,639 Speaker 1: that's a common theory. I mean, so, there are a 485 00:26:25,680 --> 00:26:28,800 Speaker 1: couple of major theories that exist now to explain why 486 00:26:29,160 --> 00:26:31,800 Speaker 1: humans ancestors lost a lot of the body hair they 487 00:26:31,840 --> 00:26:34,199 Speaker 1: originally had. And we don't know the answer, but some 488 00:26:34,359 --> 00:26:38,119 Speaker 1: fairly plausible answers seemed to be that that it helped 489 00:26:38,160 --> 00:26:41,960 Speaker 1: with with heat dispersal uh, and that it was maybe 490 00:26:42,040 --> 00:26:45,520 Speaker 1: a very good sexual selection signal. It it showed off 491 00:26:45,600 --> 00:26:47,640 Speaker 1: I don't have any lice on me because look how 492 00:26:47,680 --> 00:26:50,399 Speaker 1: little hair I have. And it turns out that I 493 00:26:50,400 --> 00:26:53,399 Speaker 1: think there are better explanations like that, And again we 494 00:26:53,400 --> 00:26:55,840 Speaker 1: don't know them for sure, but they seem like very plausible, 495 00:26:56,240 --> 00:26:59,360 Speaker 1: fitting with the evidence, explanations for all of these traits 496 00:26:59,359 --> 00:27:02,000 Speaker 1: that are answered through the aquatic ape theory. So why 497 00:27:02,000 --> 00:27:03,840 Speaker 1: do we stand up on two legs? We don't know 498 00:27:03,880 --> 00:27:06,520 Speaker 1: the answer, but a good candidate for that seems to 499 00:27:06,560 --> 00:27:09,000 Speaker 1: be that we were using our hands for things we 500 00:27:09,080 --> 00:27:12,440 Speaker 1: adapted to have to want to have free hands, uh, 501 00:27:12,480 --> 00:27:15,639 Speaker 1: and other things like oh, a common one that's cited 502 00:27:15,680 --> 00:27:18,720 Speaker 1: for the aquatic ape hypothesis is that why do we 503 00:27:18,760 --> 00:27:22,200 Speaker 1: have voluntary control over our breath? Right, we wouldn't need 504 00:27:22,280 --> 00:27:25,200 Speaker 1: that unless we were trying to be able to dive 505 00:27:25,280 --> 00:27:29,360 Speaker 1: underwater to get you know, marine mollusks or something is prey. 506 00:27:29,400 --> 00:27:32,560 Speaker 1: But what if we evolved voluntary control of the breath 507 00:27:32,600 --> 00:27:35,600 Speaker 1: because we needed to speak, right, to speak to seeing, 508 00:27:36,080 --> 00:27:38,760 Speaker 1: you know, so to communicate with each other, with each other, 509 00:27:39,440 --> 00:27:43,480 Speaker 1: that these are activities that require control of breath. Yeah, so, 510 00:27:43,640 --> 00:27:45,680 Speaker 1: I guess my main takeaway is that, you know, I 511 00:27:45,720 --> 00:27:47,800 Speaker 1: don't want to slam aquatic ape too hard. It's not 512 00:27:47,880 --> 00:27:50,679 Speaker 1: like an odious theory or something. It's just that I 513 00:27:50,720 --> 00:27:54,680 Speaker 1: think it's something that is. It's unfortunately sticky, and there 514 00:27:54,720 --> 00:27:58,080 Speaker 1: are better hypotheses more in line with the actual evidence. 515 00:27:58,119 --> 00:28:00,840 Speaker 1: We have to explain the same morphull logical features that 516 00:28:00,920 --> 00:28:04,080 Speaker 1: people appeal to the aquatic ape theory to explain. All right, Well, 517 00:28:04,080 --> 00:28:05,880 Speaker 1: on that note, let's take one more break. But when 518 00:28:05,880 --> 00:28:08,040 Speaker 1: we come back, we will we'll get to some more 519 00:28:08,080 --> 00:28:12,040 Speaker 1: good stuff. Discussing surfer's ear in human remains but also 520 00:28:12,080 --> 00:28:18,040 Speaker 1: in the remains of Neanderthals are So I think all 521 00:28:18,080 --> 00:28:20,719 Speaker 1: this stuff about surfer's ear is fascinating in and of itself, 522 00:28:20,760 --> 00:28:23,320 Speaker 1: but the the extra cool thing here is that surfer's 523 00:28:23,359 --> 00:28:26,800 Speaker 1: ear is detectable in human remains, right, because it's not 524 00:28:26,880 --> 00:28:30,280 Speaker 1: just soft flesh. They're like bony protruser. Yes, so we 525 00:28:30,359 --> 00:28:33,280 Speaker 1: can we can look to coastal humans of the past 526 00:28:33,800 --> 00:28:37,000 Speaker 1: and judge to what degree they were interacting with cold water, 527 00:28:38,000 --> 00:28:40,280 Speaker 1: and then we can also based on that, determine how 528 00:28:40,320 --> 00:28:43,240 Speaker 1: such acts were divided between the genders based on the 529 00:28:43,280 --> 00:28:49,160 Speaker 1: skeletal remains. Yeah. For instance, in December of researchers from 530 00:28:49,200 --> 00:28:53,680 Speaker 1: Washington University in St. Louis discovered skeletal evidence of surfer's 531 00:28:53,680 --> 00:28:57,160 Speaker 1: ear in a pre Columbian Panamanian village. They were looking 532 00:28:57,200 --> 00:28:59,960 Speaker 1: at a hundred twenty five skulls from nine burial side 533 00:29:00,440 --> 00:29:03,400 Speaker 1: and they found seven cases in males, one in female. 534 00:29:04,000 --> 00:29:06,240 Speaker 1: So this is this is interesting. You think of Panama 535 00:29:06,280 --> 00:29:09,400 Speaker 1: and you think of you may think of warmer waters, 536 00:29:09,440 --> 00:29:11,800 Speaker 1: but the water in the Gulf of Panama is actually 537 00:29:11,880 --> 00:29:15,640 Speaker 1: quite cold between January and April. And the researchers believe 538 00:29:15,720 --> 00:29:18,360 Speaker 1: that the divers here, that the remains that they found 539 00:29:18,360 --> 00:29:22,720 Speaker 1: were likely specialized pearl divers uh probably going after stuff 540 00:29:22,760 --> 00:29:26,640 Speaker 1: like like mother of pearl or or the orange and 541 00:29:26,680 --> 00:29:30,160 Speaker 1: purple pearls that derived from two species of thorny oysters. 542 00:29:30,200 --> 00:29:32,520 Speaker 1: These were these were popular in the region and you 543 00:29:32,560 --> 00:29:37,360 Speaker 1: also find these artifacts among the veried dead in these 544 00:29:37,400 --> 00:29:41,920 Speaker 1: grave sites. Also, Spanish explorers would later record the activities 545 00:29:41,960 --> 00:29:44,240 Speaker 1: of such pearl divers as well as you know, staying there. 546 00:29:44,280 --> 00:29:48,080 Speaker 1: They were trained since childhood to dive down four fathoms 547 00:29:48,120 --> 00:29:51,080 Speaker 1: that's twenty four ft or seven point three meters deep. 548 00:29:51,560 --> 00:29:54,440 Speaker 1: My ears are hurt and just thinking about uh so, 549 00:29:54,520 --> 00:29:57,120 Speaker 1: you know, surface certainly like these would have been individuals 550 00:29:57,160 --> 00:29:59,719 Speaker 1: diving down into those cold waters of training from an 551 00:29:59,720 --> 00:30:03,880 Speaker 1: early age and developing these bony protrusions that would there 552 00:30:03,880 --> 00:30:07,320 Speaker 1: were then detectable um you know, you know ages later 553 00:30:07,960 --> 00:30:09,760 Speaker 1: when we look back and try and figure out how 554 00:30:09,760 --> 00:30:12,240 Speaker 1: they lived. So, you know, it's a little things like 555 00:30:12,280 --> 00:30:14,600 Speaker 1: that that are insightful about it. But of course we're 556 00:30:14,600 --> 00:30:17,560 Speaker 1: talking about the recent past. We're talking about human remain 557 00:30:17,840 --> 00:30:20,880 Speaker 1: you know, almost sapiens. Is there is there a reason 558 00:30:20,920 --> 00:30:24,320 Speaker 1: you brought up neandertals early on? I feel like there was. Yes, 559 00:30:24,360 --> 00:30:26,320 Speaker 1: we've got a connection here, and that's because there's a 560 00:30:26,440 --> 00:30:30,840 Speaker 1: very recent study and this one came from Washington University. Uh, 561 00:30:31,040 --> 00:30:35,840 Speaker 1: Eric trink Us at All, author to paper External auditory 562 00:30:35,840 --> 00:30:41,360 Speaker 1: exococis among Western Eurasian Late Middle and Late Pleistocene humans 563 00:30:41,360 --> 00:30:44,160 Speaker 1: and this was published in p LS one. So, uh, 564 00:30:44,320 --> 00:30:46,960 Speaker 1: just a refresher about the Neanderthals, who we've we've talked 565 00:30:46,960 --> 00:30:49,080 Speaker 1: about on the show before and we'll continue to talk 566 00:30:49,120 --> 00:30:53,560 Speaker 1: about because there's always some sort of cool Neanderthal related 567 00:30:53,640 --> 00:30:57,680 Speaker 1: story coming out. Uh, they are our closest extinct relatives. 568 00:30:57,800 --> 00:31:00,840 Speaker 1: They lived in Eurasia two dred thousand to thirty thousand 569 00:31:00,920 --> 00:31:05,480 Speaker 1: years ago. We don't know exactly what happened to the Neanderthals. 570 00:31:05,520 --> 00:31:09,440 Speaker 1: They likely transitioned from they were out likely originally transition 571 00:31:09,480 --> 00:31:14,320 Speaker 1: to transition from Homo antecessor to Homo neanderthal insis a 572 00:31:14,400 --> 00:31:16,880 Speaker 1: hundred and fifty thousand years ago, and then they wouldn't 573 00:31:16,840 --> 00:31:20,440 Speaker 1: extinct thirty thousand years ago. Now we're continuing to learn 574 00:31:20,440 --> 00:31:23,200 Speaker 1: a great deal about them, how they differed from us physically, 575 00:31:23,280 --> 00:31:26,360 Speaker 1: but also what their culture may have consisted of. They 576 00:31:26,360 --> 00:31:31,680 Speaker 1: were ideal cold weather hominids, shorter and stockier than Homo sapiens. 577 00:31:32,120 --> 00:31:34,560 Speaker 1: They had large brains, but it seems that their brains 578 00:31:34,640 --> 00:31:38,320 Speaker 1: were far more suited for intense visual processing rather than 579 00:31:38,360 --> 00:31:41,440 Speaker 1: social processing, which would have been needed in the lower 580 00:31:41,560 --> 00:31:44,880 Speaker 1: light northern climates of Europe. Homo Sapiens, on the other hand, 581 00:31:45,000 --> 00:31:49,200 Speaker 1: are ultimately the evolutionary project product of higher light regions 582 00:31:49,240 --> 00:31:54,720 Speaker 1: of Africa. So enter this new study from Eric Trinkaus. 583 00:31:54,920 --> 00:31:58,440 Speaker 1: At All, they examined well preserved ear canals and the 584 00:31:58,520 --> 00:32:03,440 Speaker 1: remains of seventy seven ancient humans, including Neanderthals and early 585 00:32:03,480 --> 00:32:07,240 Speaker 1: modern humans of the Middle too late Plistocene epoch of 586 00:32:07,320 --> 00:32:11,880 Speaker 1: western Eurasia. So the rate of Homo sapiens surfer's ear 587 00:32:12,400 --> 00:32:15,360 Speaker 1: was more or less standard, but half of the twenty 588 00:32:15,360 --> 00:32:20,440 Speaker 1: three Neanderthals sampled had e A and their cases were 589 00:32:20,480 --> 00:32:23,160 Speaker 1: mild to severe, and we're seeing it roughly twice the 590 00:32:23,240 --> 00:32:28,120 Speaker 1: frequency of Homo Sapiens examples. So the obvious explanation would 591 00:32:28,120 --> 00:32:32,160 Speaker 1: be that Neanderthals simply foraged in cold waters more than 592 00:32:32,200 --> 00:32:34,920 Speaker 1: Homo sapiens, and that might well have been part of it. 593 00:32:35,760 --> 00:32:38,880 Speaker 1: Certainly it highlights that the water, the cold waters were 594 00:32:39,040 --> 00:32:42,640 Speaker 1: part of their foraging uh you know, realm. But it 595 00:32:42,760 --> 00:32:44,920 Speaker 1: also could mean that they just had an even greater 596 00:32:45,040 --> 00:32:48,640 Speaker 1: genetic predisposition for E A because again, humans have a 597 00:32:48,680 --> 00:32:52,160 Speaker 1: pre disposition for E A. Uh, and we see that 598 00:32:52,200 --> 00:32:55,880 Speaker 1: in modern human genetics as well. So here's just a 599 00:32:55,920 --> 00:32:59,320 Speaker 1: quick quote from from drink House about the study. Quote 600 00:32:59,320 --> 00:33:04,960 Speaker 1: and exceptionally high frequency of external auditory exotosis among Neanderthals 601 00:33:05,160 --> 00:33:08,840 Speaker 1: and a more modest level among high latitude earlier Upper 602 00:33:08,880 --> 00:33:13,400 Speaker 1: Paleolithic modern humans indicate a higher frequency of aquatic resource 603 00:33:13,520 --> 00:33:17,280 Speaker 1: exploitation among both groups of humans than is suggested by 604 00:33:17,280 --> 00:33:21,640 Speaker 1: the archaeological record. In particular, it reinforces the foraging abilities 605 00:33:21,680 --> 00:33:25,239 Speaker 1: and resource diversity of the Neanderthals. Well, that's interesting. So 606 00:33:25,280 --> 00:33:29,959 Speaker 1: it's saying that this is an indication that maybe humans 607 00:33:30,040 --> 00:33:33,440 Speaker 1: and especially neandertals of the time, we're spending more time 608 00:33:33,520 --> 00:33:36,960 Speaker 1: foraging in the water than other evidence in the archaeological 609 00:33:37,000 --> 00:33:41,840 Speaker 1: record would predict. Just another example of possible evidence for 610 00:33:41,840 --> 00:33:47,200 Speaker 1: for neandertal exploitation of marine resources for for food or whatever. 611 00:33:47,440 --> 00:33:49,280 Speaker 1: Is A is a paper I was looking at from 612 00:33:49,520 --> 00:33:52,240 Speaker 1: P and A S from two thousand and eight by Stringer. 613 00:33:52,320 --> 00:33:54,720 Speaker 1: At all that found is I was looking at the 614 00:33:54,760 --> 00:33:58,920 Speaker 1: Gibraltar region and the authors said that what we find 615 00:33:59,000 --> 00:34:02,760 Speaker 1: indications that inertals had knowledge of the geographic distribution and 616 00:34:02,800 --> 00:34:05,800 Speaker 1: behavior of their prey. We present here the evidence from 617 00:34:05,840 --> 00:34:11,680 Speaker 1: Gibraltar sites showing that Middle Paleolithic humans exploited not only mollusks, 618 00:34:11,800 --> 00:34:15,520 Speaker 1: but also seals, dolphins, and fish through a wide spread 619 00:34:15,600 --> 00:34:20,000 Speaker 1: of time. Dolphins and seals. So we got Neanderthals of 620 00:34:20,040 --> 00:34:24,239 Speaker 1: the period potentially hunting marine mammals, not quite wailing, but 621 00:34:24,320 --> 00:34:27,600 Speaker 1: a modest form of marine mammal hunting. And yeah, and 622 00:34:27,560 --> 00:34:31,120 Speaker 1: then in the process of doing it, developing surfers here, 623 00:34:31,200 --> 00:34:34,160 Speaker 1: possibly to the point of of deafness. And and by 624 00:34:34,200 --> 00:34:36,920 Speaker 1: the way, there's a there's another paper paper there was 625 00:34:37,000 --> 00:34:42,239 Speaker 1: also from Drinkos from in which he and his team 626 00:34:42,280 --> 00:34:46,200 Speaker 1: found an old, older Neanderthal from about fifty thousand years 627 00:34:46,200 --> 00:34:50,720 Speaker 1: ago who had suffered multiple injuries and become deaf. As such, 628 00:34:51,040 --> 00:34:53,239 Speaker 1: he argued that the elder must have relied on the 629 00:34:53,280 --> 00:34:56,200 Speaker 1: help of others to avoid prey and survive well into 630 00:34:56,239 --> 00:34:59,279 Speaker 1: his forties. So, you know, sort of like sandwiching these 631 00:34:59,280 --> 00:35:02,000 Speaker 1: two separate it studies together, it like it kind of 632 00:35:02,280 --> 00:35:05,080 Speaker 1: paints this picture you know of these you know, these 633 00:35:05,360 --> 00:35:09,400 Speaker 1: these these Neanderthals of foraging in the cold waters, diving 634 00:35:09,440 --> 00:35:12,480 Speaker 1: down for Mala's going after these uh uh, these other 635 00:35:12,880 --> 00:35:16,239 Speaker 1: marine creatures, and in doing so, like the the the 636 00:35:16,280 --> 00:35:18,920 Speaker 1: older members of the society, at least the ones that 637 00:35:18,960 --> 00:35:22,360 Speaker 1: are that are engaged in the aquatic foraging. Uh, you know, 638 00:35:22,400 --> 00:35:25,320 Speaker 1: going deaf and then having to depend on other members 639 00:35:25,360 --> 00:35:28,839 Speaker 1: of their society to survive. So I know you've been 640 00:35:28,840 --> 00:35:32,640 Speaker 1: picturing them as Patrick Swayze the entire time. Well no, 641 00:35:32,840 --> 00:35:35,240 Speaker 1: but but for some reason, when I first read the headline, 642 00:35:35,560 --> 00:35:38,080 Speaker 1: like last week or the week before, my my mind 643 00:35:38,160 --> 00:35:41,280 Speaker 1: instantly went to point break. It is the surfing movie. 644 00:35:41,440 --> 00:35:45,040 Speaker 1: Uh par excellence. Wait what about what about Surf Ninjas. 645 00:35:45,120 --> 00:35:47,040 Speaker 1: I've never seen Surf Ninjas. Can't vouch for it. I 646 00:35:47,040 --> 00:35:48,640 Speaker 1: have anything. I guess we'll have to come back and 647 00:35:48,719 --> 00:35:50,879 Speaker 1: check out Surf Ninjas. I just looked it up. Oh 648 00:35:50,960 --> 00:35:55,920 Speaker 1: it has Rob Schneider in it. That one don't know, 649 00:35:56,480 --> 00:35:59,439 Speaker 1: uh not that I can see right here unless he's 650 00:35:59,440 --> 00:36:04,120 Speaker 1: a cameo. Okay, it's goott Leslie Nielsen, tone Loke, Rob Schneider, 651 00:36:04,400 --> 00:36:08,359 Speaker 1: Ernie Rayas Jr. And All Star Gas. All right, well, 652 00:36:08,640 --> 00:36:11,320 Speaker 1: we'll have to leave it there. But you know again, 653 00:36:11,480 --> 00:36:14,640 Speaker 1: Neandertal's continue to be a topic of interest. And they're 654 00:36:14,640 --> 00:36:16,319 Speaker 1: just there's always so many there are always so many 655 00:36:16,320 --> 00:36:20,440 Speaker 1: great uh uh, potentially interesting studies that are coming out 656 00:36:20,480 --> 00:36:22,200 Speaker 1: about them.
