" I picked this out because of recent news items about Neanderthal genes in modern humans, something the author dismisses, even though the book is only a few years old. That shows how quickly this area of knowledge is changing. At first, the author's speculations on the behavior of Neanderthals and their interactions with Cro-Magnon was a bit too speculative for me, but a few chapters in, the evidence and interpretation seems more rigorous.
