this is absolutely retarded, and i take it that it's intended to be.

body hair is actually largely a vestigial trait, meaning we're evolving to have less hair and not more hair. look at a chimp and look at a human and take notes on the direction that facial hair is evolving. so, we don't need to ask why men evolved hair, we need to ask why they haven't gotten rid of it yet, or, more specifically, why men have been slower to lose their facial hair than women have been.

that means that a better question to ask is whether the fact that men still grow facial hair makes them less evolved than women, who have largely evolved past it. and, that is a question that likely has to do with sexual selection, rather than any sort of competition. the answer is basically "yes".

but, any question that starts with "why did men evolve beards?" is completely backwards. men did not evolve to have facial hair, they are in the process of losing it - and are clearly behind the curve in doing so.
