A rationale for evolutionary studies of literature

I identify converging lines of evidence for the proposition that the human mind has evolved, argue that the evolved character of the mind influences the products of the mind, including literature, and conclude that scholarly and scientific commentary on literature would benefit from being explicitly lodged within an evolutionary conceptual framework. I argue that a biocultural perspective has comprehensive scope and can encompass all the topics to which other schools of literary theory give attention. To support this contention, I appeal to axiomatic logic: the behavior of any organism is a result of interactions between its genetically determined characteristics and its environmental influences. Summarizing the debate over the adaptive function of literature, I argue that literature and its oral antecedents are adaptations, not merely by-products of adaptations.
