"Perhaps we should not be surprised by such statistics: after all, men seem to have an overwhelming attraction to breasts. Isn’t a woman’s wish for an enhanced bust line just a natural response to a primal desire to attract a mate? Many contemporary thinkers would suggest that this is the case. They invoke the notion of sexual selection in their arguments, arguing that some time long, long ago in the human evolutionary past, some males became erotically aroused by females with visibly enlarged breasts, choosing them more often as sex partners than their “flat-chested” sisters, thus maintaining this trait in human populations. Some writers even argue that men’s attraction to breasts was a key to the survival of early humans.
