Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
Cultural evolution is an evolutionary theory of social change. It follows from the definition of culture as "information capable of affecting individuals' behavior that they acquire from other members of their species through teaching, imitation and other forms of social transmission". [1] Cultural evolution is the change of this information ...
In Boyd and Richerson's view, cultural evolution, operating on socially learned information, exists on a separate but co-evolutionary track from genetic evolution, and while the two are related, cultural evolution is more dynamic, rapid, and influential on human society than genetic evolution.
The effect, then unnamed, was put forward in 1896 in a paper "A New Factor in Evolution" by the American psychologist James Mark Baldwin, with a second paper in 1897. [1] [2] The paper proposed a mechanism for specific selection for general learning ability. As the historian of science Robert Richards explains: [3]
In contrast to genetic programs, cultural evolution investigates how culture itself may evolve (Mesoudi, 2009 [7]). Gene-culture coevolution studies how culture and genetic evolution influence each other, ultimately shaping behavior, as well. Cultural evolution and evolutionary psychology may not be as disparate as one may think, though.
In cultural attractor theory, a cultural attractor is a "destination" that cultural ideas tend to go towards over time. To say that there is an attractor is just to say that, in a given space of possibilities, transformation probabilities form a certain pattern : they tend to be biased so as to favor transformations in the direction of some ...
The embryo itself at a very early period can hardly be distinguished from that of other members of the vertebrate kingdom." [ 7 ] Darwin also published his observations of the development of one of his own sons in 1877, noting the child's emotional, moral, and linguistic development.
Cultural selection theory has so far never been a separate discipline. [2] However it has been proposed [3] that human culture exhibits key Darwinian evolutionary properties, and "the structure of a science of cultural evolution should share fundamental features with the structure of the science of biological evolution".
