 What explains our gender diversity?  Is biology destiny?  Are we shaped by our cultures?  Is the answer an interplay of biology, culture, as they fuse during development?

 In domains where men and women have faced similar challenges: regulating heat with sweat, developing tastes that nourish, growing callouses where the skin meets friction, the sexes are similar. Even when describing the ideal mate both men and women put traits such as “kind”, “honest”, and “intelligent” at the top of their lists. But in domains pertinent to mating, evolutionary psychologists contend that regardless of species, guys tend to act like guys.
