Then explain why beauty is more a feminine trait than a male trait. In other words, explain the 80/20 rule.
Beauty reflects fitness on a superficial level, based on physical characteristics exhibited by previous generations. It's a statistical estimate. As such, it is highest for normative individuals.
If you think of a fitness distribution graph, which most likely looks like a bell curve, where do you think beautiful people stand ? I posit that they are certainly not a right section delimited by a fitness threshold, because that would include the exceptionally fit people, who must be mutants and thus probably are not beautiful.
I believe beautiful people stand in a narrow band in the middle of the curve. This is also suggested by a study that was out some time ago. They were trying to characterize beauty rigorously, and they concluded that beautiful faces were those that were the closest to average faces.
It is also crucial for women to avoid mating with mutants, regardless of their fitness level, because mutant sperm increases the risk of a fatal pregnancy. A mutant yet fit male can compensate for this risk by impregnating more females, but a female can't, her life is literally at stake. That's why women targe men in the middle of the fitness curve instead of say the last righ portion : it is the safest in terms of reproductive abilities.
This IMHO also explains the direction in which Pareto principle applies in human attractiveness. The fitness distribution has a much larger variance for men, because men can have a much larger offspring than women. As a result, a much fewer proportion of men fit into the narrow central band. Thus the 80/20 rule.
Basically, my point is that the main selective pressure for females is on parturition, not on whatever athletic or intellectual traits which are required to be a good hunter gatherer.
This, IMHO, means that beautiful people can by no means be considered "superior" human beings. At best, they are just average.
