Two NOVA episodes of a series called First Peoples suggests that when Homosapiens met both Neanderthals and Erectus, there was interbreeding rather than violence, etc. The genetic evidence is clear in the first case, since all non-Africans have some Neaderthal DNA admixture.
The images and re-enactments in the series, however, assume that this interbreeding was peacefully consensual.
No room whatever is given to the notion that bride-stealing or raiding and taking the females, etc (while killing all the males) entered into it.
Who is making an unlikely assumption here, me or them?
