Gene-culture coevolution of language: measurement-interval dependence of evolutionary rate

Tsubasa Azumagakito, Reiji Suzuki and Takaya Arita

Abstract (Excerpt)

Understanding the origin and evolution of language is key to understanding humans. The relationship between the biological evolution of language ability and the cultural evolution of language itself is extremely complex and shrouded in controversy because these mechanisms interact with each other despite the difference in their time scales (Mesoudi et al., 2011). The concept of coevolution between language and brain, in which language adapts to the brain and the brain adapts to language, is considered important in integrating biological and cultural evolution of humans (Deacon, 1997).
