The growing interest in dual-inheritance models of human evolution has
focused attention on culture as a means by which ancestors transmitte
d acquired phenotypic characteristics to their descendants. The abilit
y 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 mos
t analyses of inclusive fitness. This essay proposes that traditional
stories, or myths, can be seen as a way in which ancestors influence t
heir descendant-leaving success by influencing the behavior of many ge
nerations of their descendants. The myth of Oedipus is used as an exam
ple of a traditional story aimed at promoting proper behavior and coop
eration among kin. This interpretation of the Oedipus myth is contrast
ed with Freudian and structuralist interpretations.
