According to this overly familiar story, differences between the sexes are shaped by past evolutionary pressures―women are more cautious and parenting-focused, while men seek status to attract more mates. In each succeeding generation, sex hormones and male and female brains are thought to continue to reinforce these unbreachable distinctions, making for entrenched inequalities in modern society.
