I'm in the swimmning pool. Humans expose their skin. There is one fact which, being so widely known, no one notices: the females of the human species have little body hair. The little they have is so carefully removed. There is a whole industry devoted to hair removal.
Are women aware of why they do not want body hair?
Darwin attributed to sexual selection the loss of body hair in humans. He assumed that ancestral males chose females without body hair.When one sex's preferences evolve more than the other in a certain direction (in this case to hair loss), the other sex is "dragged through the slipstream". That is, partial nudity of the man had been dragged by the total nudity of women, but never fully reached it, which is why men are still more hairy than women.
Innovations in the preferences of males of a species, and corresponding changes in the appearance of female, is mutually reinforcing, in a runaway process that inextricably link them in and drag them farther and farther in the same direction. This tendency serves no compelling reason, it is merely a fortuitous path that has taken the evolutionary trend.
