  • Scientists might seem like the only group of people in the world who

  • Aren't really into a good gossipy sex scandal, but that, in fact, my friends, is not true at all

  • They love to talk about sex

  • Especially when it's the sex lives of our prehistoric ancestors

  • So, scientists are currently gossiping up a storm about the fact that our early ancestors,

  • The first homo sapiens, may have interbred with some other species

  • Which is weird

  • It's long been accepted by the scientific community that homosapiens, like me

  • And probably you

  • Originated in Africa around 200,000 years ago

  • As far as we can tell, they stayed there for about 140,000 years,

  • Until they started to get frisky and struck out into the unknown

  • One of the things that those adventurous humans discovered out there in the wide world

  • Was an older, more primitive, bigger-boned, species of great ape that we call Neanderthal

  • You may call them NeanderTHals but we, and the scientific community, call them NeanderThals

  • Because that's what they called themselves

  • Actually, it's because that's what the cave where their first fossils were found is called

  • It was NeanderThal. Not NeanderTHal.

  • It's just how they spell it

  • Neanderthals are, of course, related to humans, but their evolutionary lines had split about 350,000 years before

  • But, just because Neanderthals and humans were not the same species,

  • Did that prevent them from getting it on?

  • No

  • And it appears that we were similar enough species that we were actually able to create viable offspring

  • Studies have shown that, despite the fact that Neanderthals went extinct about 40,000 years ago

  • They live on

  • In us

  • According to this research, between one and 4 percent of human DNA is actually Neanderthal DNA

  • So, you might as well unstitch your family crest from your smoking jacket

  • But, Neanderthals might, actually, not be the only ancient hominids that humankind had intimate relations with

  • The recently discovered Denisovans,

  • Which probably shared more in common with Neanderthals than with humans

  • Are showing up in the genome of people all over southeast Asia

  • So, it turns out that we had a lot more choices of people

  • Or, you know, sort-of people

  • To mate with back in the olden days

  • But, we're not done messing with your conception of what humanity is yet,

  • Because turns out that some of your ancestors may, in fact, have had sexy times with gorillas

  • The reason they think this is not to do with our genome, it's to do with the genome of lice

  • And, stick with me, because yeah

  • I bet you're probably clicking away from the video right now

  • So, most species of mammals have one species of lice that's specific to them

  • It lives on them and only them, but all over them

  • Now, humans are a little different

  • Because we have isolated pockets of hair

  • We actually have two species of lice

  • We have head lice and we have pubic lice

  • And that's different from every other mammals' lice

  • But, our pubic lice?

  • Is very, very, surprisingly and upsettingly similar to the species that lives on gorillas

  • No!

  • God, no!

  • Why did we even look into this?

  • But, even if our ancestors were having sex with the ancestors of gorillas

  • Which, hopefully, they weren't

  • I'm still keeping that as a possibility in my mind

  • It probably was happening like 3.3 million years ago

  • So, you probably don't have to run straight to the shower and scrub your skin off with a pumice stone

  • At the moment

  • But, still, dang!

  • Australopithecus

  • You dirty dog

  • If you ever want to watch an episode of Scishow again

  • And I understand if you don't

  • But, if you do, please subscribe

  • And you'll be able to learn more horribly disturbing facts like the ones that we learned today

  • Also, if you have questions, or comments, or ideas for other episodes of SciShow,

  • You can get in touch with us on Twitter and on Facebook

  • And, of course, in the YouTube comments below, where we will always be happily answering questions

  • And we'll see you next time
