Clan of the Cave Bear

Modern DNA analysis, mitochondrial vs whole genome puts a pretty dark slant on the movie Clan of the Cave Bear. No mitochondrial Neanderthal DNA in humans means that no Neanderthal women mated with Sapiens men. 3% Neanderthal DNA in the whole genome means that a lot of Sapiens women were, shall we say, used by Neanderthal men. Maybe they were incorporated into the Neanderthal clan, but it seems unlikely to me.

Neanderthals seem to have been the apex predator, with Sapiens surviving pretty well on wit and guile. But as Neanderthals were bigger, stronger and possibly more intelligent I suspect that a Sapiens man trying to mate with a Neanderthal woman would lose some valuable anatomy parts. However a foraging Sapiens woman would be helpless if encountered by a hunting party of Neanderthals or even a lone Neanderthal hunter.
