There is a non-fiction book ("Buried Alive") written by a dentist who has performed several tests on Neanderthal skulls and jaws. I cannot remember the author's name, but was pretty convincing. Using several pieces of equipment, he came to the conclusion that the skulls of Neanderthals could not be produced in only 40 years (the common accepted lifespan of Neanderthals).

I wonder what was the basis of his conclusion that such bone development could not have occurred within 40 years? Bone growth rates in modern Homo sapiens - the kind of people who live indoors most of the year, work at a desk, and never have to bring their next meal with a hand axe?
