So, all this talk about men having sex with chickens and goats and dolphins and whatever misses the point entirely IMHO. In fact, this is one of those very rare times when I would say an argument seems revealing of androcentric thinking.
And the reason why I'm excluding Cro-Magnon male/Neanderthal female pairings as any kind of general rule is because we don't find mixed communities in the archeaological record, and in order for those admixtures to remain in the ultimate human gene pool, you have to have the Neanderthal women stay in the Cro-Magnon community.
And who the heck knows if that's even conceivable. Could they be domesticated? No one has the slightest clue. The assumption itself is yet another example of 'humanizing' Neanderthals in my view. For all we know, a Neanderthal female would never do anything but bite, kick, and claw until you killed her or let her go.
And one final point that I made in yesterday's thread: Neanderthal women were hardling wilting lilies such as that ridiculous reproduction above attempts to suggest. A Neanderthal female was about as musclebound as a Cro-Magnon male. A Cro-Magnon trying to rape a Neanderthal might very well wish she'd ran away!!
