Dual inheritance theory. Gene-Culture evolution

Dual inheritance theory

Dual inheritance theory, (DIT), sometimes called gene/culture coevolution, posits that humans are products of the interaction between genetic evolution and cultural evolution. DIT assumes that culture, (including cultural transmission and cultural evolution), is both influenced by and constrained by genes via psychological adaptations and that culture, in turn, contributes to selection pressures on genes. The results of these interactions can be a mix of both adaptive and maladaptive traits within a population. Another way of conceiving DIT is as an approach that integrates evolutionary theory, cultural theory, and learning theory.
