Dual inheritance theory
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, developed in the 1960s through early 1980s to explain human behavior as a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. Genes and culture (DIT suggests) continually interact in a feedback loop: changes in genes can lead to changes in culture which can then influence genetic selection, and vice versa.
