Why Women Don't Fall for Hairy Guys Remains a Scientific Mystery


Live Science: One common theory for our relative hairlessness suggests that women long ago adopted a preference for less hairy guys as a way to avoid lice and other nasty bloodsuckers that might call a pelt home.

But new research suggests that this so-called "ectoparasite avoidance hypothesis" may not explain the evolution of human hairlessness. In fact, women prefer relatively hair-free guys across the board, according to new research published online Sept. 13 in the journal Archives of Sexual Behavior. This preference for smooth skin holds whether or not parasite risk is high.
