Evolutionary psychologist Satoshi Kanazawa believes that women are getting better looking over time:
Physical attractiveness is a highly heritable trait, which disproportionately increases the reproductive success of daughters much more than that of sons.

If more attractive parents have more daughters and if physical attractiveness is heritable, it logically follows that women over many generations gradually become more physically attractive on average than men.
