WEBVTT - Why do humans have body hair?

0:00:00.280 --> 0:00:02.840
<v Speaker 1>Brought to you by the reinvented two thousand twelve camera.

0:00:03.160 --> 0:00:07.600
<v Speaker 1>It's ready. Are you welcome to stuff you should know

0:00:08.200 --> 0:00:11.600
<v Speaker 1>from house Stuff Works dot Com? Hey, and welcome to

0:00:11.600 --> 0:00:14.760
<v Speaker 1>the podcast. I'm Josh Clark, Chuck Bryant. How are you doing? Man?

0:00:16.160 --> 0:00:20.800
<v Speaker 1>I am well, that sounded very unsure. Are you feeling

0:00:20.880 --> 0:00:23.320
<v Speaker 1>the same way? Is it? Is it? Chuck and I

0:00:23.320 --> 0:00:26.720
<v Speaker 1>are recording on a Monday. Jerry's forcing us to um.

0:00:26.920 --> 0:00:29.120
<v Speaker 1>Usually we record on Fridays. It's the last thing we

0:00:29.160 --> 0:00:30.960
<v Speaker 1>do in the week, which is why we're so chipper

0:00:31.040 --> 0:00:35.080
<v Speaker 1>and up drunk and um. You know this is a

0:00:35.200 --> 0:00:38.000
<v Speaker 1>this is a shift. It's different. Yeah, it's like a funeral.

0:00:38.120 --> 0:00:41.680
<v Speaker 1>It's harsh or buzz plus, it's kind of um, cloudy

0:00:41.720 --> 0:00:44.880
<v Speaker 1>out and the weather affects me. I have a sad

0:00:44.920 --> 0:00:47.720
<v Speaker 1>seasonal effective disorder, do you really? Yeah, a little bit

0:00:47.800 --> 0:00:54.400
<v Speaker 1>like diagnosed self diagnosed? Yeah? Are you also self medicating? Uh? No, okay,

0:00:54.400 --> 0:00:59.160
<v Speaker 1>I'm not into that. Give for you, Chuck. Um, all right, Well,

0:00:59.160 --> 0:01:01.400
<v Speaker 1>I have a question for you far away. Did you

0:01:01.440 --> 0:01:02.960
<v Speaker 1>ever when you were a kid, did you have one

0:01:02.960 --> 0:01:07.240
<v Speaker 1>of those little plastic shavers, little razors? Yes? Did you?

0:01:07.880 --> 0:01:10.280
<v Speaker 1>Did you use it or did you just leave it around? Yeah,

0:01:10.280 --> 0:01:13.759
<v Speaker 1>I remember getting into my dad's shave cream and playing

0:01:13.800 --> 0:01:17.039
<v Speaker 1>around like I had facial hair. Me too, And now

0:01:17.040 --> 0:01:19.880
<v Speaker 1>we do have facial hair. I know. It's kind of like, Um,

0:01:19.880 --> 0:01:21.880
<v Speaker 1>when I was a kid, I when I was like seven,

0:01:22.120 --> 0:01:24.200
<v Speaker 1>all I wanted to do was mow the lawn right

0:01:24.560 --> 0:01:29.000
<v Speaker 1>more than anything else. And then come eight, I, um,

0:01:29.040 --> 0:01:31.160
<v Speaker 1>I actually got to mow the lawn and the first

0:01:31.200 --> 0:01:33.600
<v Speaker 1>three times were heaven, and after that I was like,

0:01:33.720 --> 0:01:36.560
<v Speaker 1>you were such a chump. Yeah, the same thing was shaving.

0:01:36.600 --> 0:01:38.960
<v Speaker 1>It was it was like really exciting, but now it's

0:01:39.520 --> 0:01:41.640
<v Speaker 1>things just get kind of mundane after you do them

0:01:41.840 --> 0:01:44.040
<v Speaker 1>a number of times. Huh. Yeah, I was pretty late

0:01:44.120 --> 0:01:46.720
<v Speaker 1>to the late bloomer to the facial hair too. So

0:01:47.319 --> 0:01:50.440
<v Speaker 1>later on in high school, like my friend Jim that

0:01:50.520 --> 0:01:54.280
<v Speaker 1>you've met, Yes, he is of Arabic descent, And Jim

0:01:54.440 --> 0:01:57.640
<v Speaker 1>literally had a mustache when he was like the eighth grade.

0:01:57.800 --> 0:01:59.880
<v Speaker 1>It was one of the stin ones and he was

0:02:00.000 --> 0:02:01.600
<v Speaker 1>he's a drummer in a band, and so he had

0:02:01.640 --> 0:02:03.760
<v Speaker 1>a little like the mullet and the mustache. Yep, I

0:02:03.840 --> 0:02:06.000
<v Speaker 1>knew I knew a kid like that to. His name

0:02:06.040 --> 0:02:09.800
<v Speaker 1>was Ron. He was a Polish descent, and he actually

0:02:09.800 --> 0:02:12.160
<v Speaker 1>his voice was deep in the third grade and his

0:02:12.200 --> 0:02:15.040
<v Speaker 1>stash started coming around a little A little after that.

0:02:15.200 --> 0:02:18.040
<v Speaker 1>I developed a little later. I'm still developing, are you?

0:02:18.040 --> 0:02:21.280
<v Speaker 1>Your voice is still changing and it is very nice,

0:02:21.360 --> 0:02:26.520
<v Speaker 1>Chuck sexy? Um, have you ever wondered, though, why? How

0:02:26.560 --> 0:02:29.440
<v Speaker 1>about this first segrede. Have you ever wondered, Chuck, why

0:02:29.600 --> 0:02:33.160
<v Speaker 1>humans even have body hair? I hadn't until I read

0:02:33.160 --> 0:02:35.000
<v Speaker 1>this article, and then it kind of occurred to me. Yeah,

0:02:35.080 --> 0:02:36.799
<v Speaker 1>that's kind of weird. Why do we have hair? Actually?

0:02:36.880 --> 0:02:38.760
<v Speaker 1>This is this isn't the this isn't the first time

0:02:38.760 --> 0:02:41.080
<v Speaker 1>I thought of this. Yeah, did you think that when

0:02:41.080 --> 0:02:44.720
<v Speaker 1>you were a little kid? No anthropology student? Okay, yeah

0:02:44.760 --> 0:02:47.520
<v Speaker 1>I didn't. I wasn't down with anthropology. I remember how

0:02:47.560 --> 0:02:51.720
<v Speaker 1>we were just talking about shaving the face. Did you

0:02:51.760 --> 0:02:54.120
<v Speaker 1>know that you or I will probably spend about a

0:02:54.200 --> 0:02:59.520
<v Speaker 1>month out of our lives. Uh, shaving less than that,

0:02:59.560 --> 0:03:02.519
<v Speaker 1>but yeah, below average. I shaved. I shaved once a week.

0:03:02.560 --> 0:03:06.080
<v Speaker 1>To God, we are made for each other. Wow, all right,

0:03:06.120 --> 0:03:10.000
<v Speaker 1>well let's get to this all right? Yes? Why dose?

0:03:10.200 --> 0:03:13.160
<v Speaker 1>Why why does your hair grow? The hair on your

0:03:13.160 --> 0:03:20.800
<v Speaker 1>head grow longer than the hair on your arms, Chuck Bryant. Well,

0:03:21.360 --> 0:03:23.440
<v Speaker 1>before we go there, Josh, we need to understand a

0:03:23.440 --> 0:03:28.400
<v Speaker 1>little bit about hair. Can we go there? Uh? What

0:03:28.520 --> 0:03:30.960
<v Speaker 1>happens is when you're talking hair growth, you have cells

0:03:31.080 --> 0:03:35.080
<v Speaker 1>inside the hair follicles. They divide and they multiply, and

0:03:35.120 --> 0:03:37.920
<v Speaker 1>then space fills up inside the follicle and it pushes

0:03:37.920 --> 0:03:41.080
<v Speaker 1>older cells out because hair is actually just like the

0:03:41.160 --> 0:03:46.800
<v Speaker 1>protein keratin and dead cells right that have hardened. Right. Yeah,

0:03:46.920 --> 0:03:48.920
<v Speaker 1>that sounds kind of gnarly when it is like that.

0:03:49.000 --> 0:03:52.000
<v Speaker 1>Did you know like something like of all dust is

0:03:52.040 --> 0:03:58.080
<v Speaker 1>dead skin cells? Really? Yeah, it's like bed bugs. Not

0:03:58.160 --> 0:04:00.520
<v Speaker 1>to get off on another tangent, but all that stuff

0:04:00.520 --> 0:04:03.360
<v Speaker 1>grosses me out. Never bring a black light into a

0:04:03.360 --> 0:04:06.560
<v Speaker 1>hotel room. That's all I have to say. So, Uh,

0:04:06.600 --> 0:04:09.160
<v Speaker 1>as space calls up, pushes the older cells out, like

0:04:09.200 --> 0:04:11.920
<v Speaker 1>I was saying, and those cells harden and exit, the

0:04:11.920 --> 0:04:15.640
<v Speaker 1>follicle informs a hair shaft, which you said is mostly

0:04:15.640 --> 0:04:20.160
<v Speaker 1>dead tissue and keratin. Correct. So that's basically what's going on.

0:04:20.320 --> 0:04:24.640
<v Speaker 1>But it happens in spurts. It rests, and it active

0:04:24.640 --> 0:04:27.680
<v Speaker 1>in resting phases. So the the active phase, the growth

0:04:27.680 --> 0:04:30.719
<v Speaker 1>phase is called the antigen phase. And then there's the

0:04:30.760 --> 0:04:34.839
<v Speaker 1>telligent phase and those are resting phases. And it's strangely enough,

0:04:35.000 --> 0:04:38.440
<v Speaker 1>these the your different parts of your body go through

0:04:38.600 --> 0:04:41.480
<v Speaker 1>different phases at different times, which is what you're talking

0:04:41.480 --> 0:04:43.159
<v Speaker 1>about with the arm in the head, right, So your

0:04:43.279 --> 0:04:47.719
<v Speaker 1>arm hair has much longer telligen or resting phases than

0:04:47.920 --> 0:04:52.320
<v Speaker 1>your hair head your head hair head hair, yes, which

0:04:52.360 --> 0:04:54.159
<v Speaker 1>I usually just call hair, Which is why this is

0:04:54.160 --> 0:04:56.080
<v Speaker 1>going to be a really confusing podcast, I know, because

0:04:56.080 --> 0:04:58.599
<v Speaker 1>there's different types of hair on different parts of your body.

0:04:58.640 --> 0:05:00.800
<v Speaker 1>So yeah, let's let's key about that right now. If

0:05:00.839 --> 0:05:04.360
<v Speaker 1>we just say hair, we're talking about the head, the scalp. Okay, okay,

0:05:04.800 --> 0:05:07.400
<v Speaker 1>everything else is facial hair, arm hair. You know, there's

0:05:07.400 --> 0:05:10.159
<v Speaker 1>a qualifier. But let's go ahead and get the different

0:05:10.160 --> 0:05:11.800
<v Speaker 1>types of hair out of the way. Let's do it.

0:05:12.680 --> 0:05:16.000
<v Speaker 1>What you have in the womb um are little tiny

0:05:16.040 --> 0:05:19.640
<v Speaker 1>hairs called lenu goo. That's that's how I pronounced it.

0:05:19.680 --> 0:05:23.440
<v Speaker 1>To pick it. Uh. Then after you're born, babies grow vellus,

0:05:23.560 --> 0:05:27.560
<v Speaker 1>which is fine un pigmented hair. It yeah, that's what

0:05:27.600 --> 0:05:29.920
<v Speaker 1>I just Yeah, little baby's heads are all soft. It's

0:05:30.200 --> 0:05:34.120
<v Speaker 1>so cute there um, And then you hit puberty most

0:05:34.160 --> 0:05:39.000
<v Speaker 1>of us and the vellus hairs give way to terminal hairs,

0:05:39.040 --> 0:05:41.400
<v Speaker 1>and they're a little more coarse. And that's what you

0:05:41.440 --> 0:05:45.320
<v Speaker 1>find underneath your armpits and around your genital area or

0:05:45.360 --> 0:05:50.520
<v Speaker 1>on my back on shoulders, hairy back, Holy cow. Really yeah,

0:05:51.160 --> 0:05:52.599
<v Speaker 1>I've never seen aim of your shirt off. I'm like

0:05:52.839 --> 0:05:56.400
<v Speaker 1>class four or Robin Williams level of Harry. Wow, I'm

0:05:56.400 --> 0:05:58.839
<v Speaker 1>not quite there. It's up there. Yeah, yeah, I'm not

0:05:58.880 --> 0:06:01.040
<v Speaker 1>that bad. I have the creeper that come around the collar,

0:06:01.560 --> 0:06:05.720
<v Speaker 1>but Emily um waxes me from time to time. My

0:06:05.839 --> 0:06:08.360
<v Speaker 1>brother in law is shaved by my sister down to

0:06:08.640 --> 0:06:11.720
<v Speaker 1>where the collar of his undershirt comes. And if you

0:06:11.760 --> 0:06:14.080
<v Speaker 1>ever see him with this his shirt off, it's like hair,

0:06:14.520 --> 0:06:17.760
<v Speaker 1>no hair. It's really hilarious, like the red nacktan kind

0:06:17.800 --> 0:06:21.080
<v Speaker 1>of Yeah, that's nice. So then back to the hair

0:06:21.120 --> 0:06:23.320
<v Speaker 1>that we all think about. The hair on the scalp,

0:06:24.000 --> 0:06:27.920
<v Speaker 1>the thicker hair, eyebrows, eyelashes. That's also a terminal hair,

0:06:28.000 --> 0:06:30.560
<v Speaker 1>which is the same as um, what a lot of

0:06:30.560 --> 0:06:34.839
<v Speaker 1>people call pubic hair. Yes, it's actually the same type

0:06:34.839 --> 0:06:36.240
<v Speaker 1>of hair. You might not think so, but it is.

0:06:36.320 --> 0:06:39.760
<v Speaker 1>It's terminal. Okay, So, and then a different kind of hair,

0:06:40.000 --> 0:06:43.280
<v Speaker 1>this is distribution, not the type of hair. Uh is

0:06:43.320 --> 0:06:47.520
<v Speaker 1>androgenic and that's like your facial hair, your chest hair,

0:06:48.040 --> 0:06:52.599
<v Speaker 1>your arm hair. And it's usually stimulated by um, the

0:06:52.800 --> 0:06:56.000
<v Speaker 1>hormone testosterone. Right. So there you have and then you

0:06:56.040 --> 0:06:58.320
<v Speaker 1>add all that up together, Josh, and you get about

0:06:58.320 --> 0:07:02.520
<v Speaker 1>five million into visual hairs for an average adult, which

0:07:02.560 --> 0:07:07.080
<v Speaker 1>is strange because that's about the same density as a chimpanzee.

0:07:07.160 --> 0:07:09.240
<v Speaker 1>Did you know that I did? And this is where

0:07:09.240 --> 0:07:11.000
<v Speaker 1>it gets a little more interesting. I'll let get all

0:07:11.000 --> 0:07:15.440
<v Speaker 1>this science stuff, get all these terms out of the way. Um,

0:07:15.480 --> 0:07:17.960
<v Speaker 1>now we're talking about chimps, and this is something that

0:07:18.040 --> 0:07:20.920
<v Speaker 1>I did not know until I read this. Uh, we

0:07:20.960 --> 0:07:26.560
<v Speaker 1>actually don't have uh fewer hairs than a chimpanzee. It's

0:07:26.600 --> 0:07:28.840
<v Speaker 1>the size of the hair actual. Yeah, they're shorter and

0:07:29.040 --> 0:07:32.080
<v Speaker 1>less coarse. So we have about the same number of

0:07:32.080 --> 0:07:34.320
<v Speaker 1>hair follicles, or at least the same density of them

0:07:34.320 --> 0:07:36.560
<v Speaker 1>as a chimp. Yeah. I bet no one would answer

0:07:36.560 --> 0:07:39.800
<v Speaker 1>that unless they knew. No, but we could. Well, we

0:07:39.840 --> 0:07:41.760
<v Speaker 1>should totally go to TRIVI to night And now the

0:07:41.840 --> 0:07:43.880
<v Speaker 1>dozens of people who listen to our podcasts couldn't know

0:07:43.880 --> 0:07:48.360
<v Speaker 1>that too exactly. Um, but we also on the chimps.

0:07:48.400 --> 0:07:53.280
<v Speaker 1>We also share the same hairless parts, which is uh, lips, palms,

0:07:53.280 --> 0:07:55.320
<v Speaker 1>and soles of the feet. No hair, My I have

0:07:55.440 --> 0:08:04.240
<v Speaker 1>hair on my palms. Well, I'm not gonna go there. Hey, um, Josh,

0:08:04.400 --> 0:08:06.640
<v Speaker 1>do we need to talk about some theories? Yeah, this

0:08:06.680 --> 0:08:08.520
<v Speaker 1>is I like this. This is why I've thought about

0:08:08.520 --> 0:08:10.760
<v Speaker 1>this before, because we were taught this kind of stuff

0:08:10.800 --> 0:08:16.040
<v Speaker 1>in anthropology apology classic. Okay, so my favorite theory, this

0:08:16.080 --> 0:08:17.600
<v Speaker 1>is the one that makes the most sense to me,

0:08:18.040 --> 0:08:21.120
<v Speaker 1>is that we started losing our hair when we became bipeds.

0:08:21.800 --> 0:08:25.040
<v Speaker 1>If you look at um most primates, they have a

0:08:25.080 --> 0:08:27.480
<v Speaker 1>tendency to walk on their knuckles as well as their

0:08:27.600 --> 0:08:31.040
<v Speaker 1>their feet, and that's how they move most quickly, which

0:08:31.040 --> 0:08:33.200
<v Speaker 1>would require you have a lot of hair on your

0:08:33.200 --> 0:08:36.000
<v Speaker 1>back because then that whole area is exposed to the

0:08:36.040 --> 0:08:39.440
<v Speaker 1>sun exactly the whole point of hair. Well, actually there's

0:08:39.440 --> 0:08:43.719
<v Speaker 1>two points, right. One is to regulate body heat to

0:08:44.000 --> 0:08:46.559
<v Speaker 1>keep keep your body warm, sure, and the other is

0:08:46.600 --> 0:08:50.800
<v Speaker 1>to protect from UV radiation from the sun. Okay, pretty cool.

0:08:51.200 --> 0:08:53.319
<v Speaker 1>So once we started walking up right, we need a

0:08:53.400 --> 0:08:55.680
<v Speaker 1>hair on our head, some of our shoulders, maybe a

0:08:55.679 --> 0:08:58.679
<v Speaker 1>little on our back, some on the chest. Uh, and

0:08:58.720 --> 0:09:03.680
<v Speaker 1>then you know everything else is kind of sexual, right, absolutely. Uh,

0:09:03.720 --> 0:09:06.000
<v Speaker 1>I think about one third of our bodies are exposed

0:09:06.040 --> 0:09:09.240
<v Speaker 1>to sunlight once we started walking upright, Right, That's the

0:09:09.240 --> 0:09:11.600
<v Speaker 1>one that makes most sense to me. But that's pretty

0:09:11.600 --> 0:09:15.079
<v Speaker 1>far from the only theories. What else you got, Well,

0:09:15.120 --> 0:09:16.680
<v Speaker 1>there's another one I thought was kind of cool that

0:09:16.880 --> 0:09:20.040
<v Speaker 1>um one theory was the early man was a water

0:09:20.160 --> 0:09:24.480
<v Speaker 1>dwelling ape. So since they're in the water, uh, you know,

0:09:24.520 --> 0:09:26.000
<v Speaker 1>you don't need hair on the water. You don't see

0:09:26.000 --> 0:09:30.120
<v Speaker 1>a lot of hairy fish, no, nor hippopotami or rhinos

0:09:30.240 --> 0:09:33.080
<v Speaker 1>or any elephants. Yes, it's been a lot of time there,

0:09:33.120 --> 0:09:36.520
<v Speaker 1>and they're all mammals. They have very sparse hair growth, right,

0:09:36.559 --> 0:09:38.679
<v Speaker 1>because they're in the water a lot. Absolutely, So I

0:09:38.760 --> 0:09:40.560
<v Speaker 1>kind of like that one. Yeah, that one makes sense.

0:09:40.720 --> 0:09:42.640
<v Speaker 1>The other one that makes sense to me is that

0:09:42.720 --> 0:09:46.560
<v Speaker 1>about one point seven million years ago, we went from

0:09:46.760 --> 0:09:51.160
<v Speaker 1>a basically a forest dwelling species to kind of moving

0:09:51.200 --> 0:09:54.400
<v Speaker 1>more out in the open, right, And since we're in

0:09:54.440 --> 0:09:57.760
<v Speaker 1>the forest, we would not be exposed to the sun

0:09:57.800 --> 0:10:00.240
<v Speaker 1>as much, and it would be cooler because out of

0:10:00.280 --> 0:10:02.520
<v Speaker 1>the sun, so we would need more hair to keep

0:10:02.520 --> 0:10:05.400
<v Speaker 1>our our body temperatures higher. Right, once we move out

0:10:05.400 --> 0:10:07.960
<v Speaker 1>into the open savannah, we don't need the hair anymore.

0:10:08.000 --> 0:10:09.560
<v Speaker 1>Why do we move out? There? Was that when we

0:10:09.559 --> 0:10:13.920
<v Speaker 1>started developing, and we always move for food. It's usually food.

0:10:13.920 --> 0:10:18.199
<v Speaker 1>When is the basis of migration? That's all the good meat? Was? Yeah? Okay,

0:10:18.240 --> 0:10:19.880
<v Speaker 1>So the thing is is if we lose our hair

0:10:19.960 --> 0:10:22.600
<v Speaker 1>and we're now exposed to the sun, chuck. We still

0:10:22.640 --> 0:10:25.160
<v Speaker 1>need to protect ourselves from UV rays, but we need

0:10:25.200 --> 0:10:28.360
<v Speaker 1>to use a method that doesn't keep us hot. Right, sure,

0:10:28.920 --> 0:10:33.040
<v Speaker 1>enter skin pigment. Okay, this news to me. Okay, so

0:10:33.080 --> 0:10:36.920
<v Speaker 1>actually they have there there was this researcher in a

0:10:36.920 --> 0:10:41.160
<v Speaker 1>two thousand doctor Rosalynd Harding and Oxford, and she went

0:10:41.240 --> 0:10:45.240
<v Speaker 1>back and traced the evolution of the m C one

0:10:45.320 --> 0:10:48.600
<v Speaker 1>our gene. This is the gene that produces either a

0:10:48.720 --> 0:10:53.800
<v Speaker 1>dark pigment or a lighter reddish pigment depending on where

0:10:53.800 --> 0:10:56.040
<v Speaker 1>we live in our exposure to the sun. They closely

0:10:56.120 --> 0:10:59.760
<v Speaker 1>lived to the equator the darker pigment. And you're going

0:10:59.800 --> 0:11:05.120
<v Speaker 1>to because it protects skin from sun cancer or skin cancer,

0:11:05.160 --> 0:11:07.760
<v Speaker 1>that kind of thing. Sun cancer, like that sun cancer,

0:11:07.800 --> 0:11:11.680
<v Speaker 1>it's the worst kind um. So Professor Harding or doctor Harding,

0:11:11.720 --> 0:11:15.360
<v Speaker 1>I'm sorry, traced the mutations on this gene as they're

0:11:15.400 --> 0:11:20.120
<v Speaker 1>found in African populations, which, strangely enough, there are no mutations.

0:11:20.240 --> 0:11:24.000
<v Speaker 1>I'm sorry, there's no variation among Africans of this gene.

0:11:24.400 --> 0:11:26.320
<v Speaker 1>And if you go and you look at Asians, you

0:11:26.400 --> 0:11:30.200
<v Speaker 1>look at people of Nordic descent, Native Americans, they all

0:11:30.240 --> 0:11:32.959
<v Speaker 1>we all have the m c one ur gene, but

0:11:33.320 --> 0:11:36.720
<v Speaker 1>there's variations on it and Africans. It doesn't matter where

0:11:36.720 --> 0:11:38.960
<v Speaker 1>you go on the African continent. That's you find the

0:11:39.040 --> 0:11:42.360
<v Speaker 1>same exact gene with the same exact mutations, and that's

0:11:42.360 --> 0:11:47.000
<v Speaker 1>the birthplace of humanity. Yes, many believe so, which I

0:11:47.080 --> 0:11:51.200
<v Speaker 1>was also surprised we apparently only UM exited Africa within

0:11:51.240 --> 0:11:54.160
<v Speaker 1>the last like fifty thousand years. I thought it was

0:11:54.240 --> 0:11:56.640
<v Speaker 1>way further back than that, but I read an article

0:11:56.679 --> 0:11:58.839
<v Speaker 1>in the New York Times. It's a different and they

0:11:58.880 --> 0:12:03.200
<v Speaker 1>know sure UM. So anyway, Dr Harding traced the the

0:12:03.280 --> 0:12:07.720
<v Speaker 1>evolution of this gene through mutations back to about the

0:12:07.800 --> 0:12:11.680
<v Speaker 1>last time it swept through the African population, and she

0:12:11.760 --> 0:12:15.040
<v Speaker 1>found that that was about one point two million years ago.

0:12:15.320 --> 0:12:19.040
<v Speaker 1>Right now, the point of this is that when this

0:12:19.559 --> 0:12:22.959
<v Speaker 1>gene when this mutation would have swept through. That's darkening

0:12:23.000 --> 0:12:27.840
<v Speaker 1>everyone's pigment. Um, we would have needed it then, so

0:12:28.000 --> 0:12:30.360
<v Speaker 1>for at least the last one point two million years.

0:12:30.400 --> 0:12:35.079
<v Speaker 1>Dr Harding posits that we've been hairless. Cool. Huh, yeah,

0:12:35.480 --> 0:12:38.840
<v Speaker 1>it all makes sense a love when it comes together

0:12:38.880 --> 0:12:41.520
<v Speaker 1>like this, it all makes sense. But I also like

0:12:41.720 --> 0:12:47.160
<v Speaker 1>biological and anthropological abnormalities that don't add up. I know

0:12:47.240 --> 0:12:49.040
<v Speaker 1>you do. Let's hear about it. Well, now I don't

0:12:49.040 --> 0:12:51.240
<v Speaker 1>have Well, are you talking about the hairy guys, the

0:12:51.360 --> 0:12:53.760
<v Speaker 1>very hairy guys? Yeah, that actually wouldn't have set up,

0:12:53.800 --> 0:12:58.120
<v Speaker 1>but I'll take it. Um. We are talking about hypertrichosis, which,

0:12:58.320 --> 0:13:00.880
<v Speaker 1>um some people might have seen they called they're called

0:13:00.880 --> 0:13:04.360
<v Speaker 1>the wolf people. I don't know if they call themselves that, well,

0:13:04.600 --> 0:13:06.440
<v Speaker 1>they may not, but that's that's what they're called. In

0:13:06.440 --> 0:13:11.600
<v Speaker 1>the research I've done, Victor Larry and Gabriel Danny Ramo

0:13:11.679 --> 0:13:15.640
<v Speaker 1>Scummez are in a family of nineteen that spanned five generations.

0:13:16.360 --> 0:13:18.760
<v Speaker 1>That's their name. No, No, a family of what a

0:13:18.800 --> 0:13:23.839
<v Speaker 1>family of nineteen? Yeah, exactly, Um, well, last nineteen over

0:13:23.920 --> 0:13:26.640
<v Speaker 1>five generations. There is bound to be some genetic mutations

0:13:26.800 --> 0:13:30.560
<v Speaker 1>in a family of nineteen. Absolutely, so they all suffer

0:13:30.679 --> 0:13:34.720
<v Speaker 1>from that rare condition. It's called generalized or congenital generalized

0:13:34.880 --> 0:13:38.440
<v Speaker 1>hypertrichosis in their case. And basically what that means is

0:13:38.480 --> 0:13:42.559
<v Speaker 1>a lot of body hair. We're talking of their body

0:13:42.760 --> 0:13:45.520
<v Speaker 1>coming hair. I was looking at a picture that you have,

0:13:45.640 --> 0:13:48.800
<v Speaker 1>and you can basically see their eyes, yeah, and around

0:13:48.800 --> 0:13:50.960
<v Speaker 1>the lips, oh yes, and around the lips they look

0:13:51.040 --> 0:13:54.600
<v Speaker 1>kind of like they're wearing hairy ski masks. Yeah. Yeah.

0:13:54.880 --> 0:13:57.079
<v Speaker 1>And is that they're one of their little siblings. It

0:13:57.200 --> 0:13:59.720
<v Speaker 1>knows says it's one of their fans. Okay, they're taking

0:13:59.720 --> 0:14:01.600
<v Speaker 1>a picture with one of their fans. And there's also

0:14:01.600 --> 0:14:05.480
<v Speaker 1>a man in China named you uh xin Juan and

0:14:05.679 --> 0:14:07.480
<v Speaker 1>his claimed fame. He has the same thing. It's called

0:14:07.480 --> 0:14:10.640
<v Speaker 1>the harriest man in China, and hair covers ninety of

0:14:10.720 --> 0:14:14.640
<v Speaker 1>his body and he is trying to become a singer

0:14:15.600 --> 0:14:17.319
<v Speaker 1>apparently and make it big as a singer, which I

0:14:17.320 --> 0:14:20.880
<v Speaker 1>thought was pretty cool. Yeah. I think the the Gomez

0:14:21.000 --> 0:14:24.080
<v Speaker 1>Brothers have him beat big times well by two ye

0:14:24.280 --> 0:14:27.720
<v Speaker 1>not much and um and you was actually made his

0:14:27.920 --> 0:14:30.600
<v Speaker 1>entertainment debut at the age of six in a movie

0:14:30.640 --> 0:14:35.120
<v Speaker 1>called A Hairy Child's adventure. So early on he felt

0:14:35.160 --> 0:14:37.680
<v Speaker 1>like he was exploited somewhat, and I'm sure he was ashamed,

0:14:38.000 --> 0:14:40.080
<v Speaker 1>but he's learned to live with it and now um

0:14:40.280 --> 0:14:42.160
<v Speaker 1>kind of embraces it, which is kind of cool. A

0:14:42.200 --> 0:14:44.800
<v Speaker 1>hairy child's adventure. I'm looking that one up. Yeah, but

0:14:44.920 --> 0:14:49.600
<v Speaker 1>it's riveting. So that is hyper trichosis in a nutshell. Um,

0:14:49.680 --> 0:14:51.000
<v Speaker 1>you know, there's a lot more. Maybe we should do

0:14:51.000 --> 0:14:53.160
<v Speaker 1>a full podcast on this is pretty interesting actually, but

0:14:53.240 --> 0:14:57.320
<v Speaker 1>they you know, shaving, plucking, electrolysis, and laser removal. They

0:14:57.320 --> 0:15:00.280
<v Speaker 1>are different cosmetic things you can do to to help

0:15:00.320 --> 0:15:03.160
<v Speaker 1>that out, you know. Um, I also did a te

0:15:03.280 --> 0:15:06.000
<v Speaker 1>bit of research on that, and you can there's an

0:15:06.000 --> 0:15:09.680
<v Speaker 1>acquired version, there's genetic version, there's an acquired version, and

0:15:09.840 --> 0:15:13.360
<v Speaker 1>through malnutrition you can you can develop this well, so

0:15:13.440 --> 0:15:16.560
<v Speaker 1>your starvation diet you better watch out, buddy. That explains

0:15:16.680 --> 0:15:18.680
<v Speaker 1>the hair on the back. Is it sprouting more and

0:15:18.720 --> 0:15:21.120
<v Speaker 1>more lately? Yeah, it is, and it's getting kind of

0:15:21.160 --> 0:15:24.120
<v Speaker 1>Billy goat esque. Yeah. I had a pet goat. Did

0:15:24.120 --> 0:15:26.360
<v Speaker 1>you know that? They did not? It's good stuff. How

0:15:26.440 --> 0:15:29.880
<v Speaker 1>is its hair growth pattern? Yeah? Of course goats are

0:15:29.880 --> 0:15:34.960
<v Speaker 1>really great pets, actually very affectionate. Yeah, they are there. Um,

0:15:35.000 --> 0:15:38.680
<v Speaker 1>they can cause some serious allergies though, Yeah, I didn't

0:15:38.680 --> 0:15:40.960
<v Speaker 1>know that. You know you do now, So here's the

0:15:41.040 --> 0:15:44.880
<v Speaker 1>you nestor my goat, Hey nestor, thanks for listening. You

0:15:44.920 --> 0:15:48.120
<v Speaker 1>want to do one last thing? Sure? Okay, So what's

0:15:48.160 --> 0:15:50.600
<v Speaker 1>the deal with growing hair and armpit hair? I mean,

0:15:50.640 --> 0:15:53.800
<v Speaker 1>these places aren't exposed to the sun any longer they are.

0:15:53.840 --> 0:15:58.080
<v Speaker 1>It's at like Camp Sunshine nudist resort, right you tell me.

0:15:58.280 --> 0:16:01.200
<v Speaker 1>Camp Sunshine is actually a camp for kids with cancer,

0:16:01.240 --> 0:16:03.800
<v Speaker 1>So I doubt that's not a new distro sword. Oh yeah,

0:16:04.040 --> 0:16:08.080
<v Speaker 1>well there's another word that you're thinking of. The there's

0:16:08.120 --> 0:16:11.840
<v Speaker 1>there's no this this it's Camp Sunshine and upstate New York. Okay, yeah,

0:16:12.040 --> 0:16:14.200
<v Speaker 1>it's that's funded by the same people. Strangely, you know

0:16:14.560 --> 0:16:18.720
<v Speaker 1>it's awesome. Um. No, the the the the theory no,

0:16:19.400 --> 0:16:23.240
<v Speaker 1>I guess hypothesis not a theory yet would be or

0:16:23.280 --> 0:16:26.520
<v Speaker 1>behind why we have growin hair and aren't hair is

0:16:26.560 --> 0:16:29.240
<v Speaker 1>because these places are um where we emit the most.

0:16:29.320 --> 0:16:31.720
<v Speaker 1>Yes see, do you see where I'm demonstrating right here?

0:16:31.800 --> 0:16:34.720
<v Speaker 1>Chuck up down here. Um, these are where we we

0:16:34.800 --> 0:16:39.040
<v Speaker 1>produce the most pheromones and The hypothesis is that the

0:16:39.120 --> 0:16:41.920
<v Speaker 1>hair acts as kind of like an amplifier for these

0:16:41.920 --> 0:16:47.840
<v Speaker 1>pheromones it traps in the smells mind does interesting? Yeah, yeah,

0:16:47.880 --> 0:16:51.240
<v Speaker 1>what a grizzly topical. Christen Conger wrote this, right, Yeah,

0:16:51.800 --> 0:16:53.960
<v Speaker 1>you go Conger. If you want to read it, you

0:16:53.960 --> 0:16:56.320
<v Speaker 1>can type in why do humans have body hair? In

0:16:56.360 --> 0:16:59.920
<v Speaker 1>the handy search part how stuff works dot com. Um. Okay,

0:17:00.480 --> 0:17:03.040
<v Speaker 1>so we did that all right, So that's why do

0:17:03.200 --> 0:17:07.840
<v Speaker 1>humans have body here? Right, Chuck? Yeah, I guess although

0:17:07.880 --> 0:17:09.520
<v Speaker 1>you know, if we ever make it back into the water,

0:17:09.680 --> 0:17:12.480
<v Speaker 1>prepared to go bald, right, And it's funny hair human

0:17:12.520 --> 0:17:17.160
<v Speaker 1>head hair is become one of the more distinct features

0:17:17.200 --> 0:17:19.680
<v Speaker 1>that you know, people have hair dues, and it's it's

0:17:19.680 --> 0:17:24.600
<v Speaker 1>not it's a very cosmetic, cosmetic thing. Yeah, you know,

0:17:24.640 --> 0:17:26.760
<v Speaker 1>it's not just I mean, it's there for our to

0:17:26.800 --> 0:17:30.440
<v Speaker 1>protect our head, but it's also to look cool. Yeah,

0:17:30.520 --> 0:17:34.439
<v Speaker 1>that's what I'm trying to say. Get a mohawk maybe. Okay, Well,

0:17:34.520 --> 0:17:41.000
<v Speaker 1>let's let's plug something, Chuck, you you plug, Okay, I'll plug. Um.

0:17:41.080 --> 0:17:43.600
<v Speaker 1>So let's plug the blogs. Chuck and I have a

0:17:43.600 --> 0:17:46.680
<v Speaker 1>blog called stuff you Should Know appropriately Enough, and we

0:17:46.840 --> 0:17:49.800
<v Speaker 1>just post about all sorts of cool stuff. Chuck does

0:17:49.960 --> 0:17:55.600
<v Speaker 1>a podcast Goodness Round Up every Friday too, um and

0:17:55.800 --> 0:17:58.879
<v Speaker 1>uh yeah, we post each once a day every day

0:17:58.960 --> 0:18:01.399
<v Speaker 1>during the week and you can find it on the

0:18:01.480 --> 0:18:05.119
<v Speaker 1>right rail on the homepage of how Stuff Works dot com.

0:18:05.160 --> 0:18:08.680
<v Speaker 1>And there's our blog plug Perfect, which means sr mail

0:18:08.760 --> 0:18:13.800
<v Speaker 1>Time Josh. Today, I'm just going to call this the

0:18:13.880 --> 0:18:18.520
<v Speaker 1>Great Australian toad Wart Correction Cast. We missed quite a

0:18:18.520 --> 0:18:20.560
<v Speaker 1>few things on this one. I'm not ashamed to admit

0:18:21.320 --> 0:18:23.560
<v Speaker 1>that happens occasionally, and it happened this time. So here

0:18:23.600 --> 0:18:26.800
<v Speaker 1>we go with corrections for the dow toads calls works.

0:18:27.240 --> 0:18:30.119
<v Speaker 1>I see that part of it's been redacted, right because

0:18:30.119 --> 0:18:32.919
<v Speaker 1>someone was wrong. They wrote in and said that toads

0:18:32.960 --> 0:18:35.240
<v Speaker 1>were not in Perth. But I went back and listen,

0:18:35.320 --> 0:18:37.439
<v Speaker 1>and you said that they were heading towards Perth, and

0:18:37.640 --> 0:18:39.880
<v Speaker 1>I sent the guy linked to an article that verified

0:18:39.920 --> 0:18:42.480
<v Speaker 1>that they are indeed heading towards Perth and are gonna

0:18:42.520 --> 0:18:45.399
<v Speaker 1>make it there. So beyond that one, Josh, at one

0:18:45.400 --> 0:18:47.480
<v Speaker 1>point you said there are no predators that have figured

0:18:47.480 --> 0:18:49.520
<v Speaker 1>out how to eat the cane toad because of the

0:18:49.560 --> 0:18:54.000
<v Speaker 1>toxins on its back. And apparently, uh Australian woman wrote

0:18:54.000 --> 0:18:56.320
<v Speaker 1>in and said that crows have learned how to flip

0:18:56.359 --> 0:18:59.240
<v Speaker 1>them over and attack the belly. Yeah, the cane toad.

0:18:59.480 --> 0:19:02.639
<v Speaker 1>But that's an pleasant sensation, so thank you for that.

0:19:02.760 --> 0:19:04.879
<v Speaker 1>We don't have names. I apologize about that, folks. I

0:19:04.920 --> 0:19:08.800
<v Speaker 1>was short on time. We also mispronounced HPV, which is

0:19:09.000 --> 0:19:12.080
<v Speaker 1>I know, go ahead and say the real world, hum,

0:19:12.240 --> 0:19:16.960
<v Speaker 1>human peppioma virus, yeah right, yea, And we said Pavlova

0:19:17.040 --> 0:19:19.760
<v Speaker 1>virus and that was my fault. As we all know,

0:19:19.840 --> 0:19:22.919
<v Speaker 1>Pavlova is a dessert and it was a famous ballet dancer.

0:19:23.520 --> 0:19:25.639
<v Speaker 1>And uh, you and I are both into eating dessert

0:19:25.640 --> 0:19:27.760
<v Speaker 1>and watching ballet, so we probably at the same time too,

0:19:28.520 --> 0:19:32.280
<v Speaker 1>So that was you know. I apologize about the mispronunciation. Josh.

0:19:32.320 --> 0:19:34.479
<v Speaker 1>He said that there are alligators he said it kind

0:19:34.480 --> 0:19:38.280
<v Speaker 1>of in a flip way in Australia. Not true, it's crocodiles.

0:19:38.640 --> 0:19:40.840
<v Speaker 1>Were we drunk during there, No, we weren't. But the

0:19:40.880 --> 0:19:46.040
<v Speaker 1>list cos on I mispronounced salasilic acid. I apologize about that,

0:19:46.680 --> 0:19:49.160
<v Speaker 1>and that is the last correction, but we we should mention.

0:19:49.200 --> 0:19:52.240
<v Speaker 1>A couple of folks wrote in and talked about ways

0:19:52.240 --> 0:19:53.679
<v Speaker 1>to get rid of words that we did not know,

0:19:54.680 --> 0:19:58.480
<v Speaker 1>and duct tape was the most uh well regarded. I

0:19:58.480 --> 0:20:00.840
<v Speaker 1>mean a lot of people said, if you put duct

0:20:00.840 --> 0:20:02.160
<v Speaker 1>tape on it and leave it for a little while,

0:20:02.480 --> 0:20:03.879
<v Speaker 1>it will get rid of your work. How long is

0:20:03.880 --> 0:20:05.960
<v Speaker 1>a little while? Did you get an impression? No? I

0:20:06.000 --> 0:20:08.600
<v Speaker 1>didn't until the word goes away? Yeah, I would guess so.

0:20:09.359 --> 0:20:13.080
<v Speaker 1>And then Chris from l A. He calls it Lower Alabama,

0:20:13.119 --> 0:20:16.440
<v Speaker 1>which obviously think it's funny. He said breast milk and

0:20:16.520 --> 0:20:19.000
<v Speaker 1>I haven't heard that one, so that is unverified, but

0:20:19.000 --> 0:20:21.760
<v Speaker 1>that's what Chris says. Chris just may have the thing maybe,

0:20:21.800 --> 0:20:25.840
<v Speaker 1>so yeah, so well, yeah, thank you for all those corrections.

0:20:25.840 --> 0:20:27.280
<v Speaker 1>Do you want to get the oak Claire thing out

0:20:27.280 --> 0:20:30.640
<v Speaker 1>of the way now, I'll go ahead. So, uh, it's

0:20:30.680 --> 0:20:34.119
<v Speaker 1>not you Claire Wisconsin, it's l Claire Wisconsin and Wisconsin

0:20:34.480 --> 0:20:38.160
<v Speaker 1>folks wrote in and said no, no, no, yeah, actually yeah,

0:20:38.200 --> 0:20:41.080
<v Speaker 1>I guess we should say it's O clear wiscantin Wisconsin. Yeah.

0:20:41.200 --> 0:20:44.919
<v Speaker 1>So yeah, thanks for everybody who wrote in to correct us. Um,

0:20:45.280 --> 0:20:48.080
<v Speaker 1>whether you were correct or not. Uh, you know, if

0:20:48.080 --> 0:20:50.359
<v Speaker 1>you mentioned Perth, that's okay. The ass he's loved it

0:20:50.359 --> 0:20:52.280
<v Speaker 1>though they love hearing podcasts about themselves. We got a

0:20:52.280 --> 0:20:53.800
<v Speaker 1>lot of good feedback right now, we'll have to do
