- 0:00Speaker 1: Brought to you by the reinvented two thousand twelve Camray.
- 0:03Speaker 1: It's ready. Are you welcome to Stuff you should know
- 0:08Speaker 1: from house Stuff Works dot com? Hey, and welcome to
- 0:16Speaker 1: the podcast. I'm Josh Clark. There's Charles W. Chuck Bryant.
- 0:21Speaker 1: Someone asked me on Facebook what the w stood forward?
- 0:24Speaker 1: You see that? And I thought, and you said, will Amina, Yeah,
- 0:26Speaker 1: it's not true, but I'm not telling I know what.
- 0:29Speaker 1: It's Dandsbard. I don't know if I know your name.
- 0:32Speaker 1: I'm not telling. Why don't I know that? I'm doubting
- 0:36Speaker 1: reality right now? Okay, all right, moving on? What's your
- 0:39Speaker 1: shut up? Buddy? Um, I don't really have a setup, Chuck. Frankly,
- 0:44Speaker 1: I'm getting a little sick of my own setups? Do
- 0:46Speaker 1: you have one? Okay, let's talk about Twins? That is
- 0:49Speaker 1: not a tuma. How's that? That's pretty good from the
- 0:52Speaker 1: movie Twins. Yeah, No, that's from Kindergarten Cop. It's so lame. Yeah,
- 0:58Speaker 1: I can't believe I give that. It's okay, man, you
- 1:01Speaker 1: got the you got the exit down. Perfect. Twins was
- 1:03Speaker 1: when he sang the yackac don't talk back, don't talk back,
- 1:06Speaker 1: don't talk back. You. Okay, So twins, Yes, we're talking
- 1:14Speaker 1: about twins obviously, um or we're talking about kindergarten cop
- 1:18Speaker 1: to toss up at this point. Actually, um, let's go
- 1:21Speaker 1: with twins, chuckers. All right. So you've known some twins,
- 1:24Speaker 1: I'm sure in your life. Yeah, I've done a few.
- 1:27Speaker 1: I used to know a lot more back when I
- 1:28Speaker 1: was in school. Um, I knew twins. I don't know
- 1:32Speaker 1: any now, I don't think. Yeah, I don't know actively
- 1:36Speaker 1: know any twins. You never jog with any of them. Okay,
- 1:41Speaker 1: so you are familiar then, as I'm sure most people are.
- 1:44Speaker 1: There not entirely uncommon, although there's a lot fewer of
- 1:47Speaker 1: them than one might imagine, especially identical twins. Right, Fraternal
- 1:52Speaker 1: twins are actually way more common. Uh, And we'll get
- 1:55Speaker 1: into how these things are made. And by these things,
- 1:57Speaker 1: I mean people who are twins to will soon be
- 2:01Speaker 1: corralled like gingers. Right, Yes, two thirds more common I
- 2:05Speaker 1: think is is the fraternal twins. Okay, Um, I guess
- 2:09Speaker 1: to to get to the point of how twins are made,
- 2:12Speaker 1: we should maybe talk a little bit about how babies
- 2:15Speaker 1: are made. And what we're talking about are called singletons
- 2:19Speaker 1: like you me, Jerry, Jerry, you're not a twin, are you? Okay,
- 2:24Speaker 1: Jerry says no, So we're all singletons, is what people
- 2:26Speaker 1: like us are called, very unique little snowflakes. Yeah, uh so, Chuck,
- 2:32Speaker 1: let's talk about how a singleton is made. Okay, I'll
- 2:35Speaker 1: get the ball rolling. We're not going to talk about
- 2:37Speaker 1: the nasty, dirty things that go into making babies. We'll
- 2:42Speaker 1: just go with the science of it all. Uh about
- 2:46Speaker 1: midway through a women's menstrual cycle, she releases an egg. Yes,
- 2:51Speaker 1: that's that's what it sounds like. Think so as it
- 2:54Speaker 1: travels down the fallopian tube, and then, uh, that single
- 2:59Speaker 1: egg is for eyes by a little swimmer, a little
- 3:02Speaker 1: spermy guy, right, and a bunch of them are coming
- 3:05Speaker 1: at it at once. Yeah, imagine that's rather intimidating. And
- 3:08Speaker 1: apparently I understand that um, brothers brother sperm related sperm
- 3:14Speaker 1: can recognize one another in the uterus and will tag
- 3:18Speaker 1: team to like get there faster. They'll draft, or they'll
- 3:21Speaker 1: they'll connect, and they'll try to like put other people
- 3:23Speaker 1: out teammates in a NASCAR race exactly. But um, when
- 3:27Speaker 1: they get to the egg gets every man for himself, right,
- 3:30Speaker 1: And so the sperm gets to the egg and fertilizes it. Yes,
- 3:35Speaker 1: and then um, what you have About a day and
- 3:37Speaker 1: a half later, it's conception, and then it's called a
- 3:40Speaker 1: z I got right. And then after that it divides
- 3:43Speaker 1: into the fertilized egg divides into two yeah. Uh, and
- 3:47Speaker 1: this is we're talking about single tents. Don't don't get
- 3:49Speaker 1: all crazy yet, the twins. The fertilizing divides into two.
- 3:54Speaker 1: And then right four days later it is about one
- 3:57Speaker 1: d cells keeps dividing and it's called a blast asist. Right, well,
- 4:02Speaker 1: you keep hogging all the great words. And then the
- 4:06Speaker 1: sixth day after that, the blast assist and plants the
- 4:08Speaker 1: uterine wall. And that's where it just states into human being.
- 4:12Speaker 1: And along the way, we all developed vestigial tails. Did
- 4:15Speaker 1: you know that? Yeah, I've heard that fall off for
- 4:18Speaker 1: most people. Yeah. And if not, what are you called
- 4:21Speaker 1: or what is it called? It's called a vestigial tail. Okay,
- 4:27Speaker 1: I can't know there's a name for like being born
- 4:30Speaker 1: with stuff like that, And I can't remember. We have
- 4:33Speaker 1: an article on this site. I think Clambert wrote it. Um, okay,
- 4:36Speaker 1: so chuck uh. Week nine, you've got a fetus Prior
- 4:41Speaker 1: to that, it's an embryo, and as the baby develops, um,
- 4:45Speaker 1: it's surrounded by a fluid filled amniotic sac right, that's
- 4:49Speaker 1: where it gets all of the food and oxygen and
- 4:52Speaker 1: all the things little little fetus needs to progress, right,
- 4:55Speaker 1: and it evacuates its bowels and its little tinkler into
- 4:58Speaker 1: the umbilical core. Right. Yeah. Uh and so today, nine
- 5:03Speaker 1: months later, approximately singleton, a little singleton, not necessarily simpleton,
- 5:10Speaker 1: but definitely singleton, right, right, So that's normal, regular old,
- 5:14Speaker 1: straight up, I have a new, little single baby. Right.
- 5:19Speaker 1: So what happens when you have twins? There's two types? Right, Yes,
- 5:23Speaker 1: we talked about identical infraternal. There's much more egg heading
- 5:26Speaker 1: names for those than that. Yeah, monozygotic is identical and
- 5:30Speaker 1: dizygotic is fraternal. So we're we'll go with can we
- 5:34Speaker 1: call him identical infraternal? Okay? Uh so starting with let's
- 5:39Speaker 1: we'll start with fraternal, right, Yeah, that's an easy one. Yeah,
- 5:42Speaker 1: they're pretty simple in fraternal. Twins, by the way, don't
- 5:45Speaker 1: have any more shared DNA than you know, Chuck and
- 5:48Speaker 1: his very handsome brother share. Yeah, I wish I shared
- 5:51Speaker 1: that much with my brother. Um, so what what happens
- 5:55Speaker 1: is the the mom releases two eggs rather than one
- 6:00Speaker 1: in the dad uh hits them with the sperm. Yeah,
- 6:04Speaker 1: like fifty million sperm, right, and then one gets in
- 6:07Speaker 1: and then another gets in and you have to developing. Yeah,
- 6:12Speaker 1: it's basically the same thing. It's like having two Singleton's
- 6:15Speaker 1: at the same time, baking two buns in the same oven. Right.
- 6:19Speaker 1: And with with the die zygotic twin, I'm sorry, a
- 6:22Speaker 1: fraternal twin, you've got three possible sets of combinations, two males,
- 6:27Speaker 1: two females, or a male and a female. And actually
- 6:29Speaker 1: male and female are the most common. They represent half
- 6:32Speaker 1: of all, um fraternal twins. Yeah, those are my favorites.
- 6:36Speaker 1: Mine to love it. Stephen Katie Duty. I don't know
- 6:40Speaker 1: any personally, although Scott and Stacy Freylick were my brother's age,
- 6:44Speaker 1: and um, I just always thought that was the coolest thing. Yeah,
- 6:47Speaker 1: they're all they're very close, they're they're always very sweet. Yeah,
- 6:51Speaker 1: where you're sweet. Yeah, and plus the whole you know,
- 6:54Speaker 1: the brother protecting the sister and the sister setting up
- 6:56Speaker 1: their brother with her friends. Yeah, it's a great It's
- 6:58Speaker 1: it's the perfect superlation and boy girl fraternal twins are
- 7:02Speaker 1: super cute. Yes, we need a T shirt that says
- 7:04Speaker 1: that not like those weirdos that look alike. Um, alright,
- 7:10Speaker 1: chuck uh. The same thing can happen with multiple births, triplets.
- 7:14Speaker 1: We have triplets that listen to us as we know,
- 7:17Speaker 1: tri zygotic, right and so on. Sure, Now with a
- 7:21Speaker 1: monozygotic birth, UM, you've got one egg that is fertilized
- 7:27Speaker 1: by the sperm, and it splits into two after it's
- 7:32Speaker 1: fertilized and starts developing two identical human beings. That's called
- 7:39Speaker 1: cool science. It really is the fact that this can happen.
- 7:42Speaker 1: I love it. And the sooner the split happens, say
- 7:45Speaker 1: within day two, the more independent the children are going
- 7:49Speaker 1: to be in utero. Right, they're they're going to have
- 7:52Speaker 1: their own amniotic sacks. They're going to have their own placenta.
- 7:56Speaker 1: As time wears on the U and the division occurs later,
- 8:02Speaker 1: they could have the chance of having fused placenta UM,
- 8:06Speaker 1: fused amniotic sacks. And this is not necessarily a good thing. Actually, no,
- 8:11Speaker 1: you can UM if you share a placenta. And sometimes
- 8:15Speaker 1: the twins will not develop equally because one twin is
- 8:18Speaker 1: hogging all the nourishment then the other and that's called
- 8:21Speaker 1: fetal growth restriction with just like Danny DeVitto and um
- 8:26Speaker 1: Arnold Schwartzen, Yes, that was that the scenario. Yeah, I
- 8:29Speaker 1: remember they said, they said, Uh, Danny DeVito was like
- 8:33Speaker 1: an accident. They weren't expecting him. He comes to realize
- 8:36Speaker 1: that he's after birth and it was really sad. It
- 8:39Speaker 1: was a sad point in the movie. That's what he said.
- 8:42Speaker 1: He's like, I'm after birth, right, it was sad slash
- 8:45Speaker 1: funny frank, Yeah, but I imagine that that's what happened.
- 8:49Speaker 1: Arnold just kind of took all of the a nourishment
- 8:53Speaker 1: for himself, leaving little Danny DeVito with very little. The
- 8:56Speaker 1: stingy governatory and Josh. Another thing can happen called twin
- 9:00Speaker 1: to twin transfusion syndrome, and that is when the twins
- 9:05Speaker 1: are sharing circulation, so they can actually transfuse blood from
- 9:09Speaker 1: one to the other. But that can be bad because
- 9:11Speaker 1: the donor twin can you know, hog some of that
- 9:16Speaker 1: some of the blood and uh will be unusually small,
- 9:19Speaker 1: whereas the recipient twin will have too much blood and
- 9:23Speaker 1: be unusually large for their age, developing baby small baby
- 9:27Speaker 1: in the same womb at the same time fighting for
- 9:31Speaker 1: their stuff, right what It's something that UM I thought
- 9:34Speaker 1: was really interesting. In this article, which is written by
- 9:36Speaker 1: Catherine Near, she's one of our head editors in A
- 9:39Speaker 1: Twin and a Twin UM, she refers to herself in
- 9:43Speaker 1: first person as the author in this throughout UM. She
- 9:47Speaker 1: mentioned that, UH, twins that have UM undergone twin to
- 9:51Speaker 1: twin transfusion syndrome or t T t S for those
- 9:55Speaker 1: in the know, UM can actually the circulation can be
- 9:58Speaker 1: separated by laser. Do you know how much Dough, the
- 10:03Speaker 1: surgeon who who performs in utero operations charges, I imagine
- 10:09Speaker 1: where does that fit into the health care package? That's
- 10:11Speaker 1: what I want to and the accounts for like sixty
- 10:13Speaker 1: of it and that's like one surgery. Yeah, but that's
- 10:17Speaker 1: my calculation. I would imagine that really tricky specialized stuff.
- 10:21Speaker 1: It really is, but it can be done, and you
- 10:23Speaker 1: kind of want to do it because one twin can
- 10:25Speaker 1: come out of nemic the other can just be enormous.
- 10:28Speaker 1: Again like Arnold Swartzenegger and Danny de Vito, right, and
- 10:33Speaker 1: identical twins Josh. Obviously, UM can only be two males
- 10:37Speaker 1: or two females. Because they share identical genetic material. True
- 10:41Speaker 1: debt check. There's also a syndrome that's pretty that's a
- 10:48Speaker 1: lot more frequent than we once imagine, called vanishing twin syndrome,
- 10:53Speaker 1: where you start out with twins or multiples, then all
- 10:56Speaker 1: of a sudden, you're down one. And they used to
- 11:01Speaker 1: think that this was a very rare and frequent thing.
- 11:04Speaker 1: And actually, I imagine an old timey eras they had
- 11:08Speaker 1: no idea that this was happening. For the ultrasound, sure right, uh.
- 11:11Speaker 1: And then once yeah, once the ultrasound came around, we
- 11:13Speaker 1: could start to kind of track what was going on.
- 11:15Speaker 1: We discovered that the mother was actually absorbing one during
- 11:20Speaker 1: her pregnancy. Yeah, that's gotta feel a little odd. Well,
- 11:24Speaker 1: and they set of multi fetal gestations has happened. Yeah,
- 11:28Speaker 1: that's way more than I would thought. Yeah, and I
- 11:29Speaker 1: wonder if it's just nature's way of saying, like, no,
- 11:33Speaker 1: eight is too many. You know, seven that's fine, but
- 11:37Speaker 1: eight now eight is enough? Uh? And then of course, chuck,
- 11:42Speaker 1: we get to a different kind of twinning called conjoined twinning. Yeah.
- 11:47Speaker 1: I got to mention this, and this is awesome, uh,
- 11:49Speaker 1: in that no one really knows how this happens. But
- 11:52Speaker 1: the prevalent theory is that the the z I got right. Yeah, okay,
- 12:00Speaker 1: the zigo splits very late, like twelve days, which apparently
- 12:04Speaker 1: is late during just station uh, and it never fully
- 12:09Speaker 1: uh divides, It doesn't have a chance to fully divide,
- 12:12Speaker 1: And so all of a sudden you have can join twins. Yeah,
- 12:15Speaker 1: that makes that seems to be pretty logical. It definitely does. Um.
- 12:19Speaker 1: And there's a whole slew of different kinds of conjoined
- 12:22Speaker 1: twins and it's all based on where the body is fused, right. Yeah.
- 12:26Speaker 1: I won't go over all the the different categories within
- 12:30Speaker 1: the subcategories within the category, but I will give the
- 12:33Speaker 1: three main terrata didema. That's if you're joined at the
- 12:39Speaker 1: lower portion of your body. And I have to say
- 12:41Speaker 1: that includes an issio fagus which lakshmid Tatma, the little
- 12:46Speaker 1: Indian girl who was born with her twin, her headless twin.
- 12:50Speaker 1: She basically looked like the goddess Lakshmi. Yeah, and actually
- 12:55Speaker 1: I checked I checked it out and make sure she's
- 12:56Speaker 1: still going strong and uh. A January twenty eighth article
- 13:01Speaker 1: in The Daily Mail had a picture of her post
- 13:03Speaker 1: surgery going to school, wearing a little plaid skirt and
- 13:06Speaker 1: a tie and waving hute cute is a button. I
- 13:09Speaker 1: thought you said Podma Lachama from Top Chef or whatever
- 13:13Speaker 1: her last name is, and I thought she was a
- 13:15Speaker 1: conjoined twin. No nice work. Well, she does have that
- 13:20Speaker 1: scar on her arm, but I knew that was from
- 13:22Speaker 1: a arm. Just thought it could have been she could
- 13:27Speaker 1: have been joined at the forearm. You know a lot
- 13:28Speaker 1: about Padma. I'm a top Chef nut. Uh. So then
- 13:33Speaker 1: we have the terrata and a didema, and that is
- 13:36Speaker 1: with one single upper body with a double lower half,
- 13:41Speaker 1: or if you're connected by a single body part, like
- 13:43Speaker 1: connected at the head, let's say, or this also includes
- 13:47Speaker 1: kids with like a from the waist down have two
- 13:49Speaker 1: sets of legs, but everything else above is just single, right,
- 13:54Speaker 1: And then the final one is terata and a katata
- 13:57Speaker 1: didema and a di didema. And that's joined somewhere at
- 14:03Speaker 1: the mid section, so maybe joined at the chest. You
- 14:05Speaker 1: might share a heart, you might share some other organs
- 14:10Speaker 1: or back to back, let's say above the spine, that
- 14:12Speaker 1: kind of thing, right, and chuck, that includes umflow Pegas
- 14:17Speaker 1: and you know who is M flow Pegas can joined twins,
- 14:20Speaker 1: don't you Ronnie and Donnie. Ronnie and Donnie Gallian. That's right,
- 14:23Speaker 1: the world's oldest living can join twins from Ohio somewhere, right. Yeah.
- 14:27Speaker 1: Then they turned fifty eight last October. Yeah. Yeah, we
- 14:30Speaker 1: did a bit on them on the webcast and they
- 14:33Speaker 1: there as you would expect, kind of cantanker us with
- 14:36Speaker 1: each other, but also like love and hug on each other.
- 14:39Speaker 1: I think it's Donnie who is uh, he gets he's
- 14:42Speaker 1: afraid of the dark, so Ronnie like cuddles him. Yeah,
- 14:45Speaker 1: it's really sweet. If you haven't ever seen any footage
- 14:48Speaker 1: of Ronnie and Donnie Galleon right hanging out, you should
- 14:51Speaker 1: look it up. They also punch each other in the
- 14:53Speaker 1: face when they're watching TV when well, they have two TVs, right,
- 14:57Speaker 1: and then they'll be watching them obviously at the same time,
- 15:00Speaker 1: and one will turn the volume up and the other
- 15:02Speaker 1: trains his volume up and it keeps going and then
- 15:04Speaker 1: somebody gets punched in the face. It's kind of funny. Yeah,
- 15:07Speaker 1: it is uh that moves us on. Josh to another
- 15:10Speaker 1: form of conjoined twin called parasitic twining, and this is
- 15:15Speaker 1: when one conjoined twin is a lot smaller and maybe
- 15:19Speaker 1: not as fully formed. And sometimes this is when you
- 15:23Speaker 1: can get like a limb and an odd part of
- 15:25Speaker 1: your body, like an arm growing out of your back
- 15:27Speaker 1: or something like that. Right, And a subset even rarer
- 15:30Speaker 1: than this is uh parasitic twinning. And by the way,
- 15:34Speaker 1: Andy Garcia was born with the parasitic twin. Didn't know
- 15:37Speaker 1: that until I read this. I didn't either. But a
- 15:39Speaker 1: very rare form of um parasitic twinning is fetus and feetsu,
- 15:44Speaker 1: which is where the twin, the unformed or underdeveloped twin,
- 15:49Speaker 1: is found in the body of the living twin, the
- 15:52Speaker 1: surviving twin UH, and often in it in the form
- 15:56Speaker 1: of a taratoma. You'll find teeth, hair, um, spinal bones, segments, bones,
- 16:04Speaker 1: uh and these are all just called teratomas. What makes
- 16:07Speaker 1: it a fetus and feet you, is when there's a
- 16:11Speaker 1: recognizable trunk and limbs. Imagine finding that in your abdomen,
- 16:16Speaker 1: which is commonly where it grows. It's really it's really sad,
- 16:21Speaker 1: is what it is. It was about to say creepy,
- 16:23Speaker 1: but but I mean imagine it's it's just a tragedy.
- 16:26Speaker 1: Imagine if you and your parents never had any idea
- 16:28Speaker 1: that you were part of a twin and then all
- 16:30Speaker 1: of a sudden it's like, oh, here he is. Well
- 16:33Speaker 1: that's where he got to, you know, and you got
- 16:35Speaker 1: would be kind of shaking. That happens a little more
- 16:38Speaker 1: often than my I'm comfortable with it, said one and
- 16:40Speaker 1: every five hundred thousand. Oh, I thought you were about
- 16:42Speaker 1: to reveal your own story. No, no, no, no no.
- 16:45Speaker 1: But I just saw one in every five hundred thousand.
- 16:47Speaker 1: My first thought was, oh, wow, that's really rare. Then
- 16:49Speaker 1: I thought, there's a lot of people on the earth,
- 16:51Speaker 1: and that's not as rare as I would like it
- 16:53Speaker 1: to be. Yeah, And with conjoint twins, actually they're rarer
- 16:56Speaker 1: than I thought. Um. Apparently, by Catherine Near's estimate, there's
- 17:00Speaker 1: only about fifty un conjoined conjoined twins unconnected conjoined twins
- 17:07Speaker 1: uh in the world today, he said, I think one
- 17:11Speaker 1: and every forty verse but only one in every two
- 17:14Speaker 1: hundred thousand live births because of conjoined twins are still
- 17:19Speaker 1: born or die you know, a day or two after birth,
- 17:22Speaker 1: which is really sad. Right, So about of conjoined twins
- 17:26Speaker 1: don't make it past the day. So the ones that do, Yeah,
- 17:30Speaker 1: and then that that five percent. Probably most of them
- 17:33Speaker 1: are going to be disconnected at some point yea if possible. Um.
- 17:37Speaker 1: Of course there have been some famous ones, right Ronnie
- 17:41Speaker 1: and Donnie. Uh, yeah, who who are the Guinness guys?
- 17:44Speaker 1: Hang and Chang bunker Archie their brother Hang and Chang.
- 17:50Speaker 1: We're born in eighteen eleven and Siam which we call
- 17:54Speaker 1: Thailand now uh. And pretty early on they realized like, hey,
- 17:58Speaker 1: we can make a lot of money off of ourselves,
- 18:01Speaker 1: so they started touring the world. Um, and they did
- 18:05Speaker 1: make a pretty respectable sum for themselves, and they actually
- 18:07Speaker 1: um retired. They think Wilkesboro, North Carolina, didn't get married
- 18:12Speaker 1: to They married sisters Sally and Adelaide Yates and the
- 18:16Speaker 1: couples together uh had to combine twenty one children and
- 18:22Speaker 1: they were never separated. That's the word I was looking
- 18:25Speaker 1: for that connected. Now they were where at the chest?
- 18:31Speaker 1: They were at the chest and and an autopsy performed
- 18:34Speaker 1: on them afterward, um, after their death, which accounts for
- 18:38Speaker 1: the word autopsy. UH found that they shared no organs.
- 18:42Speaker 1: They could have just gone skin graft. They did two
- 18:46Speaker 1: sexual organs. They had two of everything, except they were
- 18:49Speaker 1: joined at the chest, so they had two sexual Organs,
- 18:53Speaker 1: and they fathered twenty one kids with two sisters. But
- 18:57Speaker 1: they had to be a weird Saturday night. It was room.
- 19:00Speaker 1: Yeah yeah, well, yeah, everybody's in the room. That's a
- 19:03Speaker 1: managa whatever. I don't even know what that is, right.
- 19:06Speaker 1: But they lived to be sixty three actually, and then
- 19:10Speaker 1: I think they were the oldest living conjoined twins of
- 19:12Speaker 1: their time. I imagine it's probably in history. And there
- 19:16Speaker 1: was another set that's fairly um well known, I guess I.
- 19:20Speaker 1: I didn't hear them until this article. Did you read
- 19:23Speaker 1: this part? I did not about the bidden In Maids
- 19:26Speaker 1: Mary and Eliza chulk Hurst. They were born a d
- 19:31Speaker 1: in England, I take it. And they were pago pagas.
- 19:35Speaker 1: That's a fun way to say say that pig pegas. Uh.
- 19:39Speaker 1: They were pago pagas. So they were connected along their
- 19:41Speaker 1: lower back and the butt hawks so they're not facing
- 19:44Speaker 1: each other, no, which I think would probably be a
- 19:47Speaker 1: real pain. Yeah. Well, I mean there's probably no scenario
- 19:52Speaker 1: that's really easy to live with about it. They lived
- 19:55Speaker 1: to be thirty four though, that's pretty old, especially back then.
- 20:00Speaker 1: And I think Chang and hang and uh, the Biddenden
- 20:04Speaker 1: Maids died within hours of each other, which is fairly frequent.
- 20:08Speaker 1: Remember when we were researching Ronnie and Donnie. Yeah, the
- 20:10Speaker 1: doctor was talking about how, you know, sometimes people can
- 20:14Speaker 1: live up to eighteen hours, but usually it's not very long.
- 20:18Speaker 1: So can we talk about my other two favorite types
- 20:23Speaker 1: of twinning? Though favorite too. Sometimes, Josh, a woman can
- 20:29Speaker 1: release two eggs, like you would when you would have
- 20:32Speaker 1: fraternal twins, but maybe one might be let's say, two
- 20:35Speaker 1: weeks later than the other. Your husband or boyfriend or whoever, Uh,
- 20:40Speaker 1: you're having your baby with you still liberal fertilizes both
- 20:45Speaker 1: eggs at different times, and you're actually pregnant with quote
- 20:49Speaker 1: unquote twins, but one would be born two weeks after
- 20:53Speaker 1: the other, right, depending on the moment of conception. And
- 20:56Speaker 1: that's called superfication, and that's at never heard of that.
- 21:00Speaker 1: I'm kind of blown away. Yeah i am too. I'm
- 21:02Speaker 1: even more blown away, Chuck by a little term called
- 21:06Speaker 1: super feet condition. Yeah. They'd added a little extra few
- 21:09Speaker 1: letters in there because because it's like bonus. Yeah. Um,
- 21:14Speaker 1: if a woman releases more than one egg during ovulation, uh,
- 21:18Speaker 1: and two different males fertilize the eggs, so you get
- 21:22Speaker 1: sperm from one male and then spurn from another male
- 21:25Speaker 1: and both of them are fertilized and take in just
- 21:29Speaker 1: eight she can have siblings half siblings at the same time,
- 21:36Speaker 1: virtually the same time. But boom, super fee condition and
- 21:39Speaker 1: actually the first one you talked about, superfetation. They can
- 21:43Speaker 1: lead to half identical twins where um, the egg splits
- 21:49Speaker 1: before fertilization and is infertilized by two separate sperm. So
- 21:53Speaker 1: these twins actually share sev their d n A. Yeah,
- 21:57Speaker 1: polar body twins. Yeah, pretty cool term. Yeah, so that's yeah,
- 22:00Speaker 1: it's the same thing, except it's not two eggs to
- 22:03Speaker 1: begin with. It's one egg that splits. That makes sense. So, Chuck,
- 22:07Speaker 1: you want to talk about some you want to just
- 22:09Speaker 1: put some twin myths down, take them around the barn
- 22:14Speaker 1: and shoot them. Sure, or we can validate them. Yes, okay.
- 22:19Speaker 1: There's a study called the Minnesota Study of Twins Reared Apart,
- 22:23Speaker 1: and it's an ongoing four part deal where their study um,
- 22:26Speaker 1: fraternal and identical twins raised together and separate to see
- 22:29Speaker 1: like what the big all the hullabaloo is all about.
- 22:33Speaker 1: And what they found a lot of times is that
- 22:36Speaker 1: twins separated at birth identical twins, uh or I guess
- 22:40Speaker 1: fraternal too. They share a lot of the same characteristics
- 22:42Speaker 1: in life. And Jim and Jim Lewis and Springer were
- 22:48Speaker 1: separated at four weeks old, right, and they were adopted.
- 22:52Speaker 1: So note both of their first names are the same.
- 22:54Speaker 1: They were given the same first name by their adoptive parents, right,
- 22:57Speaker 1: instead of the same last name. Very odd. Uh. They
- 23:01Speaker 1: were apart until they were thirty nine years old. They
- 23:04Speaker 1: both grew to six ft tall weight exactly a hundred
- 23:06Speaker 1: and eighty pounds when they were little boys. Each one
- 23:10Speaker 1: had a dog named Toy right. Each one had been
- 23:13Speaker 1: married two times. The first wives of both were called Linda,
- 23:17Speaker 1: and the second wives of both were called Betty yea.
- 23:20Speaker 1: Each one had a son they named James Allen, which
- 23:24Speaker 1: is interesting. They and and here's another little fact for you.
- 23:29Speaker 1: My dad's name is James Allen and he had a
- 23:31Speaker 1: twin that died at birth. This is getting out of hand. Yeah.
- 23:36Speaker 1: I remember when my dad first told me that. I
- 23:37Speaker 1: was like, oh. And then a couple of years later
- 23:39Speaker 1: I was like, Wow, that's so weird to think that
- 23:42Speaker 1: I would have had an identical twin uncle. Yeah, that
- 23:45Speaker 1: just never happened. That would have changed the course of
- 23:47Speaker 1: your life entirely. Uncle look alike? How it called him? Uh? What? What?
- 23:53Speaker 1: What other things that they have in common? Each one
- 23:55Speaker 1: had driven a had a light blue Chevrolet, and they
- 23:58Speaker 1: both vacationed at past a grilled beach in Florida. Right,
- 24:01Speaker 1: here's my favorite. Uh. They both enjoyed Salem cigarettes and
- 24:05Speaker 1: Miller Lite beer. Yes, I love that one too. Um.
- 24:08Speaker 1: They were both nail biters, they both held part time
- 24:11Speaker 1: job as sheriffs. They both had migraines. And then the
- 24:15Speaker 1: little love note thing. Yeah, and uh, and how the
- 24:18Speaker 1: Mind Works, I think is what it's called Stephen Pinker's book. Um.
- 24:22Speaker 1: He he off handedly mentions that. Uh. And he's saying,
- 24:26Speaker 1: is there a gene for leaving love notes around the house?
- 24:29Speaker 1: And he's saying, twins rude apart kind of suggest Yeah, right,
- 24:33Speaker 1: they both left love notes for their wives. It's so odd.
- 24:37Speaker 1: It is what an odd characteristic to share. So they
- 24:40Speaker 1: were obviously studied in that in that Minnesota study of
- 24:43Speaker 1: twins reared apart, But they do mention I thought this
- 24:46Speaker 1: is funny that they had different hairstyles. Well, yeah, I
- 24:49Speaker 1: mean like it is easily sensationalized you know, and you
- 24:52Speaker 1: you you've got to say, like, you know, those facts
- 24:55Speaker 1: lead you to believe that they were the exact same
- 24:57Speaker 1: person in every single way. So when they said had
- 25:00Speaker 1: the mop top Beatles haircut and one had like the
- 25:02Speaker 1: pompadoor Johnny Cash with the sideburns even longer CIDs. Yeah,
- 25:06Speaker 1: so maybe they just listened to different music and well
- 25:09Speaker 1: another one was more articulate than the other, and the
- 25:12Speaker 1: other was a better writer than the articulate one. Alright, yes,
- 25:17Speaker 1: interesting stuff. Imagine having a twin with the same first
- 25:21Speaker 1: name being like hey Jim, Hey Jim. They get old
- 25:24Speaker 1: really fast, nice sideburns, nice mop top, let's go smoke
- 25:28Speaker 1: some Salem's let's oh boy um and then uh forty
- 25:33Speaker 1: eight hours the TV show did did a special on
- 25:36Speaker 1: identical twins raised Apart, and they found interesting things like
- 25:41Speaker 1: Barbara and Daphne that were twins and they both had
- 25:45Speaker 1: miscarriages and then had two boys and one girl. A
- 25:49Speaker 1: little bit of a connection there, I don't know, however,
- 25:52Speaker 1: the top that is though, are those the giggle twins? Yeah,
- 25:55Speaker 1: because they apparently had the same laugh. Well they crossed
- 25:57Speaker 1: their arms and giggle in the same way, right, which
- 26:01Speaker 1: you could have picked up from watching ALF. They could
- 26:03Speaker 1: have both been watching ALF. Yeah you never know? Yeah
- 26:06Speaker 1: did you watch ALF? Yeah? I didn't watch OFF. I
- 26:10Speaker 1: never got it. It's like a puppet. Have you ever
- 26:12Speaker 1: seen Permanent Midnight? Oh yeah, that's the guy who wrote
- 26:16Speaker 1: the first season of ALF. That's what Permanent Midnight is about.
- 26:19Speaker 1: If you go watch Permanent Midnight and then you go
- 26:21Speaker 1: watch the first season at ALF, there's a lot of
- 26:24Speaker 1: like kind of really quick, dark funny things in there
- 26:27Speaker 1: that My favorite part of that movie is when he
- 26:30Speaker 1: and Owen Wilson are had lost their drugs and Owen
- 26:34Speaker 1: Wilson says, if I was a Perka Dan, where would
- 26:36Speaker 1: I be? Great line and chuck. You know, um, twins
- 26:41Speaker 1: root apart is like a perfect natural experiment to try
- 26:45Speaker 1: to settle nature versus nurture. Yeah right, Um, it's not
- 26:50Speaker 1: always a natural experiment. And I'm making air quotes for
- 26:53Speaker 1: those of you who can't see. There's a group in
- 26:55Speaker 1: New York that was affiliated well, they had an end
- 26:59Speaker 1: with a your adoption agency in New York and I
- 27:01Speaker 1: think the sixties, and they were basically like, oh, you've
- 27:05Speaker 1: got some twins up for adoption. Make sure that this
- 27:07Speaker 1: goes this one to this family, and this goes to
- 27:09Speaker 1: this family, and then they kept tabs. So they were
- 27:12Speaker 1: like purposefully separating twins and in the adoption through the
- 27:16Speaker 1: adoption agency and then studying them like this huge longitudinal study. Uh.
- 27:22Speaker 1: And actually, uh, they apparently got some really great results,
- 27:25Speaker 1: but they became so afraid. Is apparently the public sentiment of,
- 27:29Speaker 1: you know, separating twins for the study of nature versus nurture.
- 27:34Speaker 1: Public sentiment changed. So by the eighties, I think they
- 27:37Speaker 1: concluded this twenty year study. Um, they were like, Okay,
- 27:40Speaker 1: we're just going to never talk about this for the
- 27:42Speaker 1: next sixty years. So they sealed it and I think
- 27:44Speaker 1: it's in like a the Yale University Library under lock
- 27:48Speaker 1: and key. But it's coming out in the next like
- 27:50Speaker 1: ten or twenty years. I think, Yeah, it's gonna rock
- 27:53Speaker 1: our world. Yeah that in the whole Kennedy assassination, the
- 27:57Speaker 1: truth will be out there. I don't know if that
- 27:59Speaker 1: one's overcoming out. We'll know when their dates set for
- 28:01Speaker 1: it is there. Yeah, I think so where the records
- 28:03Speaker 1: are gonna be open? Awesome, can't wait. I need to
- 28:06Speaker 1: watch more stuff they don't want you to know. Huh. Yes,
- 28:09Speaker 1: are awesome Conspiracy Theorist podcast. Yeah, uh so, Josh, we
- 28:13Speaker 1: do know that, Um, we don't know what causes the
- 28:17Speaker 1: uh the MZ twins right now, but we do know
- 28:20Speaker 1: that the rate is consistent throughout the world, which is
- 28:23Speaker 1: about one and two fifty right now. That's that doesn't
- 28:26Speaker 1: necessarily mean that, like it's every time there's what did
- 28:31Speaker 1: you say, one in to fifty or four in a thousand?
- 28:33Speaker 1: One in fifty is a little easier, okay, But it
- 28:36Speaker 1: doesn't mean that every time there's a thousand births, you
- 28:39Speaker 1: know there's four equally distributed. No, of course, not right.
- 28:42Speaker 1: But if you take the birth statistics across the entire world,
- 28:45Speaker 1: you're gonna find about four per one thousand, and actually
- 28:48Speaker 1: by ethnic group, uh it changes. African Americans tend to
- 28:53Speaker 1: have far more twins than any other group. And Africans
- 28:57Speaker 1: and I'm sorry African people of African descent um, and
- 29:01Speaker 1: Africans themselves. Sure that I think they said that Yoruba
- 29:04Speaker 1: tribe in Nigeria has forty five per one thousand births,
- 29:08Speaker 1: and that's a lot. That is a whole lot. Uh.
- 29:11Speaker 1: On the low end, Chinese people have eleven point two
- 29:15Speaker 1: per one thousand berths right, right, And that that's in
- 29:18Speaker 1: the United States, by the way, not in China. Chinese
- 29:22Speaker 1: people living in the United States, So Chinese Americans have
- 29:25Speaker 1: eleven point two per one thousand, but if you go
- 29:27Speaker 1: to China, it's like eight hundred per one thousand. I
- 29:30Speaker 1: don't think that's the right number. That is not the
- 29:31Speaker 1: right number. But um, there are a couple of factors involved,
- 29:34Speaker 1: chuck real quick. Um the the uh. I think the
- 29:38Speaker 1: follicle stimulating hormone can cause a woman to have more
- 29:41Speaker 1: than one egg. Um. And that's usually found more frequently
- 29:45Speaker 1: in heavy women and older women. Uh. And we've been
- 29:48Speaker 1: kind of trending towards he and right as far as
- 29:52Speaker 1: parents go. So twinning as a result in the US
- 29:55Speaker 1: has risen eighty or thirty eight percent and sixty five percent.
- 30:00Speaker 1: Since that's pretty big jump. Okay, so let's move along
- 30:04Speaker 1: and get rid of some myth. Dude. Twin language josh right,
- 30:09Speaker 1: also known as idea glossia and cryptophagia. That is, uh,
- 30:14Speaker 1: when some people say it, twins have like a secret
- 30:16Speaker 1: language that they speak to each other, sort of not true.
- 30:19Speaker 1: What the deal usually is is, um, let's say when
- 30:23Speaker 1: they're developing. Let's say the first little twin has like
- 30:26Speaker 1: a slower development with the language than the second twin.
- 30:29Speaker 1: The second twin will kind of hang back or mimic
- 30:32Speaker 1: and mimic mirror neurons, maybe mimic the other twin, and
- 30:36Speaker 1: then all of a sudden they kind of developed this
- 30:39Speaker 1: code if you will, right. Uh, so twin language, no
- 30:46Speaker 1: technically no, all right? Uh? And then you always hear
- 30:49Speaker 1: about twins having esp like one of them gets injured
- 30:54Speaker 1: somewhere and the other one across the country knows about
- 30:57Speaker 1: it right then or or something. So this have been
- 31:00Speaker 1: tested actually, and uh. In one experiment, it's kind of clever.
- 31:04Speaker 1: They took two twins and they put one. They put
- 31:07Speaker 1: them in separate rooms, split them up. Well, yeah, you
- 31:10Speaker 1: got to, or else they'll just cheat like crazy. I
- 31:12Speaker 1: wonder if they faked it though, and they're like they
- 31:13Speaker 1: really thought they had Donnie when they had Ronnie. Yeah
- 31:17Speaker 1: you have both, yeah, yeah, um, but you split one.
- 31:21Speaker 1: You split them up and you give one some cards
- 31:24Speaker 1: to pick to choose from with different illustrations on it,
- 31:27Speaker 1: and then the other one has the same set of
- 31:29Speaker 1: cards in another room. So you have the one that
- 31:31Speaker 1: chose to the card, the sender send the image telepathically
- 31:36Speaker 1: to the target, the recipient twin, and then the recipient
- 31:40Speaker 1: twin is supposed to choose that card. Well, the crazy
- 31:44Speaker 1: thing is is, in the first round of this experiment
- 31:46Speaker 1: they got it right like half of the time, which
- 31:48Speaker 1: is pretty significant. But then they altered the experiment a
- 31:52Speaker 1: little bit and they had a an assistant choose the
- 31:57Speaker 1: card for the twin, and then the twins sent them telepathically,
- 32:01Speaker 1: and all of a sudden it dropped the right. And
- 32:04Speaker 1: they think that it was because the twins were hitting
- 32:06Speaker 1: at because of shared preferences, not uh tell telleth telepathy.
- 32:14Speaker 1: There's something really wrong with me today. Yeah, I think
- 32:17Speaker 1: that's probably the deal. That a lot of experiments don't
- 32:19Speaker 1: show any kind of special bond. Some do, but the
- 32:22Speaker 1: same experiments show that special bond between let's say a
- 32:27Speaker 1: mother and a daughter or a brother and a sister
- 32:29Speaker 1: that aren't twins, and they think that it probably just
- 32:32Speaker 1: has more to do with um, like you said, growing
- 32:36Speaker 1: up together, shared preferences and interest, that kind of thing.
- 32:40Speaker 1: So what do you want to do celebs or movies
- 32:42Speaker 1: famous twins? Josh, have you ever heard of Mario Andretti
- 32:46Speaker 1: race car driver. Yes, no, I have been either. That's see.
- 32:51Speaker 1: I highlighted the ones that I was like. I didn't
- 32:54Speaker 1: know they had a twin because some of them obviously,
- 32:56Speaker 1: you know, like Jenna and Barbara Bush. Yeah, but they're
- 32:59Speaker 1: for turn A right. Uh yeah, Giselle Bunch in the
- 33:05Speaker 1: smoking hot model. Yeah, Jesus sister. I imagine a smoking
- 33:08Speaker 1: hot sister. She is good looking, she's her manager. She's
- 33:11Speaker 1: not model hot, but she is very attractive. Are they
- 33:15Speaker 1: identical or fraternal? Their fraternal? Vin Diesel really yeah? He
- 33:20Speaker 1: has a kind of a funny looking brother named Paul Vincent.
- 33:24Speaker 1: A picture of him. How do you name your kid?
- 33:27Speaker 1: Paul Vincent? And then Vin Diesel's a stage name, dude.
- 33:31Speaker 1: I wonder if his name is Vincent Paul. Oh. Maybe
- 33:34Speaker 1: maybe his parents were very unamazed innative, or maybe Paul
- 33:37Speaker 1: Diesel changed his name to Vincent because he thought it
- 33:39Speaker 1: was too you know. Gear Head Scarlett Johansson has a
- 33:44Speaker 1: brother named Hunter. They look a lot alike Ashton Kutcher,
- 33:49Speaker 1: Did you know that? I think that rang a bell? Actually? Yeah?
- 33:52Speaker 1: The Cutch has a brother named Michael, who has cerebral palsy. Sadly. Yes,
- 33:56Speaker 1: that does ring a bell. Yeah, and he like it's
- 33:58Speaker 1: his kind of lives for him him and has brought
- 34:00Speaker 1: a lot of awareness to that um altist. Morrissett as
- 34:04Speaker 1: a brother named Wade who cares. And Wade Morrisset is
- 34:08Speaker 1: a singer, yoga dude and a cureton. It's just like
- 34:12Speaker 1: an Indian chanter. Can we be done now? Uh? Parker
- 34:16Speaker 1: Posey as a brother named Chris Cool. I'll bet he's cool. Uh.
- 34:19Speaker 1: And then Keifer William, Frederick Dempsey, George Rufus Sutherland. Did
- 34:25Speaker 1: you know he had that many names? Yes, he has
- 34:27Speaker 1: a fraternal twin sister named Rachel. Why would you give
- 34:31Speaker 1: a kid that many names? Donald Southerland is probably smoking
- 34:35Speaker 1: a lot of something back in the day. Oh yeah,
- 34:36Speaker 1: at least he did an animal House. And then, of
- 34:39Speaker 1: course my favorite twins, Kim and Kelly deal. Kim deal
- 34:43Speaker 1: with the Breeders. Okay, well they're both in the Breeders
- 34:45Speaker 1: and Kim was in the Pixies. Pixies Uh. And before
- 34:48Speaker 1: we move on, I want to put a call out
- 34:50Speaker 1: because I saw a special one time on a TV
- 34:54Speaker 1: show about these two twins. Two I think like twelve
- 34:58Speaker 1: year old black girls in England, and they mimicked everything exactly.
- 35:06Speaker 1: They spoken stereo at the same exact time, they walked
- 35:10Speaker 1: exactly the same in synchronousy. It's like the twins in
- 35:13Speaker 1: the Shiny It's very creepy and that's exactly what they were.
- 35:16Speaker 1: And you know what happened. But one day they found
- 35:19Speaker 1: one of them drowning the other one in a creek.
- 35:21Speaker 1: Did they save the one? I don't know and I
- 35:23Speaker 1: can't find I saw this like years ago and I
- 35:25Speaker 1: have never, ever ever been able to find anything on it.
- 35:27Speaker 1: So putting the call out there to the s Y
- 35:30Speaker 1: s k army anyone knows about this, I'm dying to
- 35:33Speaker 1: know the story. Well, if you want to read one
- 35:35Speaker 1: of the better articles on how stuff works, check out
- 35:39Speaker 1: twins is type twins in the handy search bar how
- 35:41Speaker 1: stuff works dot com and that leads us to listener mail. Yes, Josh,
- 35:48Speaker 1: I have a couple of quick ones. This is from
- 35:50Speaker 1: Adrian and Canadian City, fredericton n B. What does that mean?
- 35:56Speaker 1: I have no idea. Yeah, probably he's eleven. It's called
- 35:59Speaker 1: Canadian City, New Brunswick. Or he's saying, yeah, it's hey, guys,
- 36:05Speaker 1: my name is Adrian. In case you're wondering, I'm a boy,
- 36:08Speaker 1: and surprisingly enough, I am only eleven years old and
- 36:10Speaker 1: I listen to your podcast every night. I can I
- 36:13Speaker 1: believe that thanks to you guys, I'm the smartest boy
- 36:16Speaker 1: in my class in the subject of interesting facts. And Jerry,
- 36:20Speaker 1: I have not forgotten about you. I believe that without you,
- 36:24Speaker 1: the sound effects would run for the hills. Keep up
- 36:27Speaker 1: the good work, people. Please put this in your next podcast,
- 36:29Speaker 1: because if I heard myself on the show, then it
- 36:31Speaker 1: would be one of the highlights of my life. Well,
- 36:33Speaker 1: technically you're not hearing yourself, but you're hearing Chuck read
- 36:36Speaker 1: you Adrian. But that's close enough. That's right. Jerry loved this.
- 36:39Speaker 1: When Jerry Ford did this after we had already seen it,
- 36:41Speaker 1: did she go cute, Well, i've the sound effects. They
- 36:45Speaker 1: would run for the hills and that's adorable. No, she
- 36:48Speaker 1: just wanted to remind us of her place and exactly.
- 36:51Speaker 1: And then this is from Abu and this is another
- 36:54Speaker 1: kind of call out to the fans because we said
- 36:56Speaker 1: something about Arthur the weather man in our little YouTube
- 37:00Speaker 1: bar last well, which one was at And do you
- 37:02Speaker 1: remember I had nothing to do with whatever we were
- 37:05Speaker 1: talking about it now, I don't remember. It will probably
- 37:07Speaker 1: come out after this one. No, it already came out. Okay,
- 37:11Speaker 1: But we heard from Abu that Arthur the weather Man
- 37:14Speaker 1: actually perished in the Hate the earthquake. I don't think
- 37:17Speaker 1: that's true, but we don't know if that's true. I
- 37:19Speaker 1: looked it up on the Internet and everything points back
- 37:21Speaker 1: to the single source that isn't reputable. So if anyone
- 37:25Speaker 1: out there has any information on Arthur, No, Arthur, if
- 37:28Speaker 1: you're out there, let us know you're alive. Please. Yeah,
