Evolutionary psychology of language
Evolutionary psychology of language is the study of the evolutionary history of language as a psychological faculty within the discipline of evolutionary psychology. It makes the assumption that language is the result of a Darwinian adaptation. There are many competing theories of how language might have evolved, if indeed it is an evolutionary adaptation. They stem from the belief that language development could result from an adaptation, an exaptation, or a by-product. Genetics also influence the study of the evolution of language.
