  Abstract:  Genetic Mechanisms Involved in the Linguistic Diversity. The paper is a short review of genetic mechanisms involved in linguistic differentiation. FOXP2 is the first gene relevant to the human ability to develop language. Due to the polymorphism of nucleotide patterns, it is suggested that gene FOXP2 could be the target of selection during recent human evolution. Several studies support the hypothesis of a co-evolution of human polymorphism and linguistic differentiation. In this process, migration and isolation are the most important factors involved. Differences in migration patterns of ancient people suggest that, on the long term, language was paternally transmitted. A strong correlation between linguistic and biological diversity is also emphasised. The continuous loss of linguistic and biological diversity can have important consequences for humanity.
