What’s the best title for this passage? [originaltext] Women and men differ

Women and men differ not only in physical attributes and reproductive function but also in the way in which they solve intellectual problems. Adequate evidence suggests, however, that the effects of sex hormones on brain organization occur so early in life that from the start the environment is acting on differently wired brain in girls and boys.
     Major sex differences in intellectual function seem to lie in patterns of ability rather than overall level of intelligence. We are all aware that people have different intellectual strengths. Some are especially good with words, others at using objects -- for instance at constructing or fixing things. In the same fashion, two individuals may have the same overall intelligence but have varying patterns of ability.
     Men, on average, perform better than women on certain spatial tasks. In particular, men have an advantage in tests that require the subject to imagine rotating an object or manipulating it in some other way. They outperform women in mathematical reasoning tests and in navigating their way through a rotate. Further, men are more accurate in tests of target-directed motor skills -- that is, in guiding or intercepting projectiles.
     Women tend to be better than men at rapidly identifying matching items, a skill called perceptual speed. They have greater verbal fluency, including the ability to find words that begin with a specific letter or fulfil some other constraint. Women also outperform men in arithmetic calculation and in recalling landmarks from a route. Moreover, women are faster at certain precision manual tasks, such as placing nails in designated holes on a board.
     Since with the exception of sex chromosomes, men and women share genetic material, how do such differences come about? Differing patterns of ability between men and women most probably reflect different hormonal influences on their developing brains.
