[4] [5] Cultural evolution, the domain of research focused on how culture changes through time due to different individual transmission mechanisms and population-level effects, often uses models derived from population genetics, in which agents are passive recipients of cultural traits (e.g. Bentley et al., 2004 [6]). While evolutionary ...
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 ...
The Biological Analogue for Cultural Units breaks down into 3 subunits. The first is regarding strict analogues. This means that a biological unit (traits etc.) should be related to a cultural unit. This is a way for the old biological model and the modern cultural model to correlate and solidify the point. The second is regarding trait analogues.
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.
Dual inheritance theory (DIT), developed in the late 1970s and early 1980s, has a slightly different perspective by trying to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. DIT is seen by some as a "middle-ground" between views that emphasize human ...
Cultural characteristics, also referred to as "Memes" [9] [13] (e.g., ideas, rituals, tunes, cultural fads, etc.) can replicate and spread from brain to brain, and many of the same evolutionary principles that apply to genes apply to memes as well. Genes and memes may at times co-evolve ("gene-culture co-evolution").
That is, cultural traits and genes both have the three characteristics necessary for natural selection (variation, selection, and inheritance) as well as non-selective processes, such as drift. [ 2 ] [ 3 ] [ 9 ] [ 10 ] Defining the terms "culture" and "cultural traits" are key to effective EA research. [ 11 ]
