From Wikipedia:

Dual Inheritance Theory (DIT), also known as Gene-Culture Coevolution, was developed in the late 1970s and early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. DIT is a “middle-ground” between much of social science, which views culture as the primary cause of human behavioral variation, and human sociobiology and evolutionary psychology which view culture as an insignificant by-product of genetic selection.

About its potential,

DIT has been viewed as having great potential for unifying diverse academic fields under one overarching theory. Mesoudi, et al. have identified DIT as the ideal way to build a comprehensive theory of cultural evolution to answer questions about human behavior at different temporal and spacial scales. [67] Along with game theory, Herb Gintis has named DIT one of the two major conceptual theories with potential for unifying the behavioral sciences, including economics, biology, anthropology, sociology, psychology and political science. Because it addresses both the genetic and cultural components of human inheritance, Gintis sees DIT models as providing the best explanations for the ultimate cause of human behavior and the best paradigm for integrating those disciplines with evolutionary theory. [68] In a review of competing evolutionary perspectives on human behavior, Laland and Brown see DIT as the best candidate for uniting the other evolutionary perspectives under one theoretical umbrella.


In a 2006 interview Harvard biologist E.O. Wilson expressed disappointment at the little attention afforded to DIT:

“…for some reason I haven’t fully fathomed, this most promising frontier of scientific research has attracted very few people and very little effort.”[55]

Therefore I would like to call more research on this theory, especially empirical work (experiment). I see more understanding on the brain-learning bridge (e.g. Neuropsychology) is important to advance education.
