Culture is a New Trick whose attributes have emerged from these gender differences that already existed. (Over evolutionary time, culture may not turn out to be beneficial for our species at all as we can see from the various disaster scenarios discussed on the list - it's a gamble, just like every evolutionary innovation.)
I'm all for diversity of personality types, but gender differences per se most likely will not be needed in the period of intense auto-evolution that we are approaching.
