Darwin envisioned a scientiﬁc revolution for psychology. His theories of natural and sexual selection identiﬁed two classes of struggles—the struggle for existence and the struggle for mates. The emergence of evolutionary psychology and related disciplines signals the ful-ﬁllment of Darwin’s vision. Natural selection theory guides scientists to discover adaptations for survival. Sexual selection theory illuminates the sexual struggle, highlighting mate choice and same-sex competition adaptations. Theoretical developments since publication of On the Origin of Species identify important struggles unknown to Darwin, notably, within-families conﬂicts and conﬂict between the sexes. Evolutionary psychology synthesizes modern evolutionary biology and psychology to penetrate some of life’s deep mysteries: Why do many struggles center around sex? Why is social conﬂict pervasive? And what are the mechanisms of mind that deﬁne human nature?
