Surprisingly, the study of language activity has long been conducted without any questioning of its biological function. In fact, the Human and Social Sciences (anthropology, linguistics) have long defended the idea that language appeared without any selective pressure. In this paradigm, the human being - defined as a fundamentally cultural being with few instinctive behaviors - would have "invented" articulated language (as well as writing). In this purely culturalist conception, the question of the raison d'être of language behavior has long been evacuated from scientific investigation in favor of the extensive study of the proximal and sensorimotor mechanisms that underlie it. However, asking the question of the ultimate causes of human language makes it possible to raise original questions and to answer questions that are still pending. My research aims to demonstrate that the synergy of approaches developed in linguistics and evolutionary biology can significantly advance our knowledge of this specifically human faculty. Trained as a linguist, my research interests include:(1) The study of the voice as an honest signal allowing the speaker to display - via certain vocal characteristics - his phenotypic quality and increase his reproductive success(2) The study of linguistic and genetic proximity. Following the work initially led by the geneticist L. Cavalli-Sforza, I study the genetic diversity of Arab populations in order to better understand the linguistic variability of the Arabic-speaking domain.(3) The study of the role of the family in the transmission of socially valued linguistic forms, which posits that language skills - different according to the social affiliation of individuals - participate in the social structuring of human populations.
