John Hawks has numerous posts on a recent paper suggesting that a key gene regulating human brain development might have originated in neandertals living in what is now europe. John Hawks Anthropology Weblog : 2006 11 is one example.
Hawks says to expect quite a bit of Neandertal news this week. I think most laypersons, like myself, had come to believe there was no sapiens-neandertal interbreeding. Surprises indeed.
I'll be reading Hawks' blog closely this week.
