I remember Trinkaus from Washington University is of the school that interbreeding took place. He researched a skull found in a Romanian Bear cave that had both modern hominoid and Neandertalis traits, though the DNA was Neanderthal. There were other human type bones in the cave.
I'll see what I can rustle up on Trinkhaus.
Neandertalis are hominoid. Humans didn't relace Neanderthals, just a type of hominoid replaced another hominoid.....
And I agree that we dont know if this Neanderthal in Scoobys post was murdered, killed yes, but murder...we'll never know.
On an aside regarding the current human female not being able to give birth to a neanderthal skull, the Neanderthal famale birth canal was larger but the infant skulls were not vastly different. So it is plausible that if the child didnt abort in a human female it could have fit coming out her canal if surviving full term ..Biologically could the egg be fertalised by another species and survive is the question more than the canal and skull.
If we do stick with traditional thought that the Neanderthalis skull was bigger at birth then I would say that interbreeding still may have taken place at times, but not to the level of species replacement. Hominoid male behaviour would have them protect their females from competitor species breeding, but would themselves breed with neanderthalis females as a social/physical behaviour...who could give birth to a smaller skull.
There is a theory that we outbred them not killed them off because we had bigger brains, but because we bred faster....I like this one too, but I think it was all three assumptions:
Rabbit like procreation by current humans
interbreeding between the hominoids (least occuring)
and perpetualtion of the fittest/smartest
See article
The new skull reconstructions show that Neanderthal babies grew 5 to 10% faster than modern humans. But since Neanderthals also had bigger bodies, they took about the same time to reach adulthood that we do, says Zollikofer. "The big question is, what happened to humans 50,000 years ago," he says. Early modern humans and Neanderthals now appear to have had similarly big brains at birth, that grew at similar rates. But the brains of today's babies are smaller than both of them. "Are they more efficiently organised? Or did we trade a bit of intelligence for smaller, cheaper brains that meant we could reproduce faster," he says. If so, Zollikofer speculates, we may have succeeded the Neanderthals not because we were smarter, but because we bred faster - more like rabbits.
