Résumé

This study examines the overall genetic structure of Turkic- and Indo-Iranian-speaking populations of Central Asia (Uzbekistan, Kyrgyzstan, and Tajikistan), of which ethnicities Karkalapak, Kazakh, Kyrgyz, Turkmen, Uzbek, Tajik and Yaghnobi are represented. This study is an international collaboration between American and French genetic and linguistic anthropologists. AMOVA and Mantel tests are used to examine the relationship between genetic differentiation, linguistic differentiation, and geographic distance; the results of which lead to a larger discussion of how cultural factors, such as language, influence the genetic composition of a society. Genetic samples were provided by E. Heyer and consist of mitochondrial HVR-1 sequences from 948 individuals and 8 y-chromosome microsatellites from 837 males. A linguistic distance matrix was provided to the first author by F. Manni and P. Mennecier, and contains 25 samples which represent six languages categorized into either Turkic (Karakalpak, Kazakh, Kyrgyz, and Uzbek) or Indo-Iranian (Tajik and Yaghnobi) language groups. Linguistic distances were calculated using the Levenshtein Distance method. The linguistic distance matrix was used to calculate correlation with group-pairwise genetic and geographic distance matrices. Results show significant differentiation for both maternal and paternal lineages based on sample site, ethnicity and language group. Each lineage displays the highest among-group variation based on sample site, followed by ethnicity, and then language group. However, there lacks significant relationships between genetic distance, linguistic difference, and geographic distance. The results suggest that though time, shared ethnicity and language contribute to group differentiation, but geographic proximity is a weaker factor for societies inhabiting Central Asia.
