Evolution doesn't favor anything. There is no rhyme or reason, and its only "purpose" is to pass on genetic material indefinitely. As long as a species successfully reproduces, evolution "favors" them. Everything that men and women do, whether negative or positive, is evolutionary sound as long as they pass on their genes. Women have a slight advantage in intelligence because they're less addicted to the physical sensation of orgasms, which is what the male obsession with sex is actually fixated on. A man once crashed his bike, almost rolling into traffic in order to stare and comment on my body. Sexual arousal dumbs down ones brain, it has a similar affect to that of alcohol consumption. This is a state of impairment on an individual's intelligence, and men spend much more time in carnal limbo. Women's obsession with men goes much deeper than the physical sensation of PIV, and they're less triggered by the mere sight of male physicality in an everyday context. Most women waste their lives and intellect though, so this advantage is meaningless on the grand scale, but its why women are more able to leave the primal song and dance of hetero "polite" society behind.
