“What female biology desires is "bad boy" genes for her sons so that they will survive and fight off the competition, however, the best evolutionary strategy is to marry the good guy and shag the bad guy on the side (which is what birds do). The safe nest-building good guy is great to make sure the off-spring survive childhood, the bad guy gene makes sure they survive beyond childhood and get to pass the genes on to the next generation”
If human females only select sexual partners based on the behaviors of “Bad boy” genes then the “good guy” genes would not be able to replicate and would have died out long ago.
