Why Aren't Humans Furry?

A prize-winning paper suggests that humans are hairless apes because Stone-Age mothers regarded furry babies as unattractive. Written by Judith Rich-Harris, author of The Nurture Assumption and No Two Alike, the article, "Parental selection: a third selection process in the evolution of human hairlessness and skin color. Harris' theory is that this kind of parental selection may have been an important force in evolution. If Stone Age people believed that hairless babies were more attractive than hairy ones, this could explain why humans are the only apes lacking a coat of fur. Harris suggests that Neanderthals must have been furry in order to survive the Ice Age. Our species would have seen them as "animals" and potential prey. Harris' hypothesis continues that Neanderthals went extinct because human ancestors ate them.
