Monogamous societies that allows as many females as males to grow up select more for all possible properties on the female side, including visual attractiveness. The amount of selection pressure on the male and female sides (among adults) should differ enormously between empty polygynoys societies and crowded monogamous societies (at least those that do not practice infanticide). In empty polygynous societies, all women who manage to survive until adulthood breed to their maximum. In crowded monogamous societies, more or less the same share of males and females breed, and their breeding success mostly depends on the same economic factors. The implications of all this on the female side of evolution should be huge.
