not gonna cite because it's very well established you can look it up yourself.
But there's something interesting I just cam up with today. Male and female brains differ, some areas are more pronounced in males and some more in women.
Different intelligences (spatial, verbal etc) come from different brain regions, this has also been proven by studies that showed male had better mathematical and females better verbal abilities.
Both score the same average in IQ tests, further validating that IQ is a good measure for general intelligence as two different intelligences lead to the same result. (only difference is the distribution of the curve with the women's curve being more flat)
