The genomic evidence of the antiquity of inequality—between men and women, and between people of the same sex but with greater and lesser power—is sobering in light of the undeniable persistence of inequality today. One possible response might be to conclude that inequality is part of human nature and that we should just accept it. But I think the lesson is just the opposite. Constant effort to struggle against our demons—against the social and
behavioral habits that are built into our biology—is one of the ennoblingbehaviors of which we humans as a species are capable, and which has been critical to many of our triumphs and achievements. Evidence of the antiquity of inequality should motivate us to deal in a more sophisticated way with ittoday, and to behave a little better in our own time.
