Human Sexuality

Battle of the Sexes


As any nature lover knows, males and females of the same species commonly diverge in appearance and behavior--a reflection of their differing roles in reproduction.


Take, for example, the brilliantly hued male peacock and his relatively drab counterpart, or the promiscuous sage grouse male and discriminating female.

Or the Little Yellow butterfly, whose males and females are identical in color to the human eye but quite different to that of the insect, thanks to the male's ultraviolet adornments. Consider katydid courtship, unusual in that the male is the choosy one, carefully considering his options before bestowing on his bride a precious nuptial gift. 

And then there's the prairie vole, whose pheromones appear to orchestrate a reproductive strategy rarely seen in mammals: monogamy.

Eighteenth-century naturalists interpreted plant reproductive biology through the lens of human sexuality and social customs of the day. It is surely tempting in our modern era to take the reverse tack: look to other organisms to gain insight into gender differences and social organization in our own species. 

Studies of the bonobo, for one, raise the possibility that rather than being male-centered, early human societies were female-centered.


In any event, men and women almost certainly played different roles in evolutionary history and may thus have been subjected to varying selective pressures. This could help explain alleged cognitive differences between the sexes today.
