An anonymous reader writes "The BBC reports on a new study of prehistoric skulls which suggests that Neanderthals became extinct because they had larger eyes than our species. As a consequence of having extra sized eyes, an average 6 millimeters larger in radius, more of their backside brain volume was devoted to seeing, at the expense of frontal lobe high-level processing of information and emotions. This difference affected their ability to innovate and socialize the way we, modern people (Homo Sapiens Sapiens) do. When the last Ice Age set on 28,000 years ago, Neanderthals had no sewn clothes and no large organized groups to rely on each other, hastening their fall. Yet, they were not stupid, brutish creatures as portrayed in Hollywood films, they were very, very smart, but not quite in the same league as the Homo Sapiens of Cromagnon."
