Аннотация: This chapter discusses recent advances in our understanding of the complex interplay between cultural and biological factors in language change and evolution.Three "myths" (the independence of biological and cultural evolution, a fi xed biological foundation for culture, and the cognitive uniformity of humans) are identifi ed and falsifi ed.Strong genetic biases are shown to affect language profoundly, using the example of village sign languages that emerge and complexify due to persistent high frequencies of genetic deafness in certain communities.Evidence is presented for the genetic bases of language and speech, and the extensive genetic variation within populations affecting them.Finally, it is proposed that in addition to intrapopulation variation, interpopulation differences in genetic biases that affect language and speech contribute to the emergence of linguistic diversity, through iterated cultural transmission across generations as well as communication and alignment within them.Thus, biological and cultural processes cannot be meaningfully separated when studying the cultural evolution of language. Cultural Evolution and Biological Evolution Are Two Sides of One ProcessThis chapter is about the relationship between cultural and biological evolution, as evidenced in the domain of language.Many scholars with an interest in cultural evolution operate with a set of myths or fi ctions, tacitly holding something like the following:1. Fiction of independence of biological and cultural evolution.Biological and cultural evolution are for practical purposes now independent processes, and despite the "curious parallels" between the diversifi cation
