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 or those of our
biological relatives. Social customs that enhance the odds of such transmission survive in the form of kinship bonds, courtship
rituals, altruism, taboos against female adultery, and many aspects of 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 is influenced by our biological heritage, but most doubt that either imprinting or true instincts occur in human beings.
