Rob, Barry, Dick: Sexual Selection in action

What does science have to say about why ugly men survive if, as Darwin declares, women chose which men get to reproduce?

A new study explains why we aren't all born with Brad Pitt’s perfectly chiseled features or Angelina Jolie’s pouty lips.... [M]en with greater genetic diversity in areas of the genome relating to disease defense were also rated as more attractive by women. So because these males with greater mutation rates are more likely to mate, they will pass that higher rate on to their offspring, allowing sexual selection to propagate variation through the population, a finding that likely applies to all
organisms.
This propagation means that peacocks’ tail feathers will
vary in length and that some of us definitely won’t be America’s next top model.

And some of us will be Rob, Barry & Dick....
