Fascinating article on Neandertals and their relationship to modern humans in Scientific American. My favorite quote (of many):
However the Neandertals obtained their food, they needed lots of it. “Neandertals were the SUVs of the hominid world,” says paleoanthropologist Leslie Aiello of the Wenner-Gren Foundation in New York City. A number of studies aimed at estimating Neandertal metabolic rates have concluded that these archaic hominids required significantly more calories to survive than the rival moderns did.
