In this paper we seek to build on existing mathematical studies of cultural change by exploring how the diversity of adaptive cultural traits evolves by innovation and cultural transmission when the payoff from adopting traits is both uncertain and frequency dependent. The model is particularly aimed at understanding the evolution of subsistence trait diversity, since the payoff from exploiting...

Whales and dolphins (Cetacea) have excellent social learning skills as well as a long and strong mother-calf bond. These features produce stable cultures, and, in some species, sympatric groups with different cultures. There is evidence and speculation that this cultural transmission of behavior has affected gene distributions. Culture seems to have driven killer whales into distinct ecotypes, ...

Cultural psychologists have shown that people from Western, Educated, Industrialised, Rich, Democratic (WEIRD) countries often exhibit different psychological processing to people from less-WEIRD countries. The former exhibit more individualistic and less collectivistic social orientation, and more analytic and less holistic cognition, than non-Westerners. Yet the mechanisms responsible for mai...

Demographic transition theory is developed highlighting cultural transmission pattern as key driver. Individuals maximize cultural fitness, i.e. rate of own cultural type absorbtion by future generations. With low population density, one’s culture can be picked up only by own children, thus cultural fitness equals genetic fitness, individuals allocate all energy surplus to reproduction, and Mal...

What is the mechanism that translates the individual properties of learners into the properties of the language they speak? This paper will investigate cultural transmission as this mechanism and will take up the Iterated Learning Model as a formal framework in which to address this claim. This model describes language as a special learning problem, where the output of one generation is the inp...

Population geneticists have shown that the effects of local extinction and recolonization on selectively neutral genetic diversity are sensitive to the number of individuals that migrate between groups. Here, we employ a spatially explicit metapopulation model to investigate the extent to which the effects of local extinction on selectively neutral cultural diversity and change are sensitive to...
