From Evolutionary Psychology:Trivers, Dawkins/Wilson & the Selfish Gene • Design of the mind explained by natural selection • Motives, including altruism, evolved through interactions in hunter-gatherer life style • Beauty equals health and fertility signs • Emotions evolved to benefit from cooperation without being duped by liars and cheats • Thirst for revenge best defense against aggression • Proximate causes of behavior: hunger, pleasure in sex, etc. • Ultimate evolutionary causes: food to survive, sex to procreate Ev. . and Paleontology, Child Psychology and Anthropology
