> Interbreeding did happen but it’s probably not true that Neanderthals got wholesale assimilated into Homo sapiens. More that there was some low level of interbreeding.

Why is it probably not true? It's the simplest reasoning. Why did they have to be deceived through language or annihilated, but slightly fornicated?

Seems reading the book wouldn't help me if you read it and can't argue the points on it's behalf.

I'll ask this again:

Do you know why he thought they didn't have strong language skills and how he linked that to annihilation via deception and such or was he guessing?
