In evolutionary terms women who didn't immediately fall in love with conquerors and gladly have their children were dead ends. Women who did, weren't. Place your bets on the behavior of women descended from that selective filter.
Now you sound like the IQ deniers. You don't need to find the specific genes for a behavior to identify a filter for it - humans have bred horses for speed without sequencing the horse genome.

There's more science in IQ denial than in whatever ad hoc position you've invented for this conversation. What exactly is your position? That human ancestors aren't 2/3rds female? That there weren't many many total Y chromosome replacement events around 8k years ago? What?
