To return to a hardy perennial (particularly in recent months), here's another article on sex differences in the brain. This one's in Scientific American. I particularly like the study with young vervet monkeys! I admit freely, as the mother of two sons, I believe utterly in innate gender differences, while believing just as firmly (and not in the least contradictorily) that this has no bearing on the educational and occupational opportunities that should be available to people. And do note that I went into motherhood a dyed-in-the-wool behaviorist (raised on Watson and Skinner).
