Actually humans are more likely to be affected by ridiculous notions. Because we are sentient there can be genetic drift as a result of societal preferences. For example, in its current state America may drift towards skinny big boobed women.
Obviously this is not a survival of the fittest scenario or this anorexic whores would have died out a long time ago.
