The proposed project examines the relationship between behavioural genetics, on the one hand, and cultural evolutionary theory, on the other. In particular, it focuses on whether an integration between the two fields is possible and identifies areas in which it would be most fruitful. Furthermore, it looks at the epistemic goals (such as prediction and explanation) which could potentially be furthered by such an integration. The project aims to contribute to building a integrative theoretical framework which would help both fields tackle the epistemic challenges they both face.
