An international group of researchers, based on the analysis of data on the peoples of northeast Asia, found that the grammar of the language correlates with the genetic history of the population.
It is rather difficult to uncover the history of human migration in antiquity. Scientists have long been trying to do this by combining data from archeology, genetics, cultural studies and linguistics. A team of specialists led by researchers from Tokyo and Zurich universities analyzed data on 14 peoples of 11 language families in Siberia and East Asia - Tunguska, Chukchi-Kamchatka, Eskimo-Aleutian, Yukagir, Ainu, Korean and Japanese. In addition, the genetic data of the Nivkhs, the indigenous people of Sakhalin, were obtained previously inaccessible to scientists.
The researchers compared the genomes of these populations with data on their language (grammar, phonology, vocabulary) and folk music (song structure, their style) and tried to identify correlations. It turned out that grammar best of all information about culture reflects the genetic history of peoples: by the grammatical similarity of languages, one can predict the genetic affinity of the peoples who speak them. The reverse is also true.
The analysis carried out by scientists shows that this relationship between grammar and genetics reflects contacts between populations before the emergence of language families, in prehistoric times.
