It was called evolutionary biology. Under its sway, the sexes were separated again, men into hunters and women into gatherers. Nurture no longer formed us; nature did. Impulses of hominids dating from 20,000 B.C. were still controlling us. And so today on television and in magazines you get the current simplifications. Why can't men communicate? (Because they had to be quiet on the hunt.) Why do women communicate so well? (Because they had to call out to one another where the fruits and berries were.) Why can men never find things around the house? (Because they have a narrow field of vision, useful in tracking prey.) Why can women find things so easily? (Because in protecting the nest they were used to scanning a wide field.) Why can't women parallel-park? (Because low testosterone inhibits spatial ability.) Why won't men ask for directions? (Because asking for directions is a sign of weakness, and hunters never show weakness.) This is where we are today. Men and women, tired of being the same, want to be different again.
