If you gather the berries, I'll slaughter a rabbit

For how long will we be beholden to our evolutionary past?

This article is about how men tend to be more intelligent than women (you read that right). It claims that the reason for this comes from two factors:
  1. Our hunter male ancestors had to solve complex problems to hunt. This meant the smarter ones survived. Our female ancestors who were in charge of the mindless task of collecting berries, on the other hand, could be as dumb as they pleased.
  2. Our hunter male ancestors also increased their chances of survival and reproduction if they were more competitive. Thus, not only are men more intelligent, on average, than women (by 5 IQ points!), but also they are more likely to ruthlessly pursue success.
I understand that our old Neanderthal brains are all kinds of stressed out in our new, rapidly evolving social world. But, evolution hasn't come to a standstill. The verdict doesn't have to necessarily be in forever, right? Perhaps these days men and women face tasks that are more equally challenging than before. Perhaps in a million billion years we'll close that 5 point gap.

Surely we're now (and have been for the last, say, hundred thousand years) being selected on different features of brains from those for which our hunter-gatherer relatives were rewarded.

Or are we?
