Abstract. The growing interest in dual-inheritance models of human evolution has focused attention on culture as a means by which ancestors transmitted acquired phenotypic characteristics to their descendants. The ability of cultural behaviors to be repeatedly transmitted from ancestors to descendants enables individuals to influence their descendant-leaving success over many more generations than are usually considered in most analyses of inclusive fitness. This essay proposes that traditional stories, or myths, can be seen as a way in which ancestors influence their descendant-leaving success by influencing the behavior of many generations of their descendants. The myth of Oedipus is used as an example of a traditional story aimed at promoting proper behavior and cooperation among kin. This interpretation of the Oedipus myth is contrasted with Freudian and structuralist interpretations.
