Chimps dig the Hot Mammas
Well, its actually pretty old news, dating back to a behavioural observation published in November 2006.
I really like how the behaviour gets so totally compared with humans: "...despite their promiscuous mating system, chimpanzee males, like humans, prefer some females over others. However, in contrast to humans, chimpanzee males prefer older, not younger, females."
And even we accept this diagnosis; far from being a demonistic paedophillic trend, youth-preference in humans has something to do with monogamy or something. I don't think there is very much evidence that humans prefer monogamous relationships, meaningful ones, maybe - but not necessarily life long, early in life or with only one partner.
