Yes, Europeans are more K selected - which is a measure of *paternal* investment in offspring as more or less the result of feedback loops and environmental conditions. None of that changes that women are under much less harsh selection than men.
This clearly isn't sinking in. Women (nearly) all successfully reproduced. Men were frequently weeded out. The men who were weeded out were less cooperative. The winners mated with the women of both groups. This is why your ancestors are 66% female 33% male.

This pressure was especially intense in Europe where waves of steppe nomads wiped out men and took women as wives over and over. The end result is that Euro men conquered the world because they were the end result of selection for the traits needed to conquer (cooperation).
