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.
There was a filter that didn't let certain tendencies survive - hostility to conquering men was totally and completely wiped out Since then of course evolution continued but there's not a single filter weeding out any particular behavior so you get selection for different traits
