Dual Inheritance Theory

A theoretical model that describes how genetic and cultural traits evolve jointly through distinct but interacting transmission processes—genetic inheritance and socially mediated cultural transmission—such that cultural practices can change selective environments for genes and genetic predispositions can bias patterns of cultural learning; applied at population and multi‑generational scales to ex

A theoretical framework that models human behaviour and trait evolution as the product of two interacting inheritance systems—genetic transmission and culturally transmitted information—whereby cultural processes (learning, teaching, imitation) and genetic evolution co-influence selection pressures and trait dynamics across generations.
