00:15Most modern humans today, except for people from sub-Saharan Africa, have a couple percent
00:23ancestry from Neanderthals. Maybe it's a little higher, maybe it's a little lower for an individual
00:28person. And all of this Neanderthal ancestry is the result of interbreeding between early
00:36modern humans and Neanderthals in Eurasia about 45,000 years ago.
01:02And it shows that whenever Neanderthals and modern humans have made it, there has been
01:09a preference for male Neanderthals and female modern humans as opposed to the other way around.
01:17It doesn't rule out the fact that it may just be birth incompatibility. So either side
01:23tried, but only one side was successful.
01:37And it's not the result of a strictly Darwinian survival of the fittest. This bit's good,
01:47and this bit's bad, and these people survived. But it's really the result of how we interact
01:55with each other and what our culture and society and behavior is like.
