scientists disagree about the place of instinct in human behavior. Sociobiologists argue that even complicated forms of human behavior can have an instinctive basis. They believe we have an inborn urge to propagate our own genes and those of our biological relative. social customs that enhance the odds ò such transmission survive in the form ò kinship bonds, courtship rituals,altruism, taboos against female adultery, and many aspects ò social life. other social scientists have argued that human behavior can be explained solely by learning. Psychologists today generally take a middle path. they acknowledge that human behavior í influenced by our biological heritage, but mót doubt that either imprinting ỏ true instincts occur in human beings
