Although speculation is rife that Neanderthals may have interbred with Cro-magnon (physiologically modern humans), the relatively recent period in which they (the Neanderthals) were extant would not have allowed enough time for them to have fully evolved into modern humans.Most anthropologists believe the Neanderthal and Cro-magnon co-existed for a time. If that's true they must have evolved separately.
Ha Ha Neanderthals. Can't make fire. - Far Side
The advent of good cutting tools obviated the need for massive physical strength which their bone structure indicates. Hence, thos born Neanderthals who were less robust had a better chance to survive.
Could they have bred?
isnt there 2 theories on this: 1. we killed them off.
2. or we bred with them......>which explains the looks of some central europeans.
Or both??
