The Genetic Composition of the Staroaleisk Culture Population: Statement of the Problem and First Results mtDNA
Against the intensive studies of the genetic composition of early nomads from the Altai-Sayan mountain system, a number of Scythian populations from the adjacent forest-steppe zone remain unexplored by paleogenetic methods. This article presents the first results of a paleogenetic study of the Staroaleisk culture carriers from the Firsovo-XIV burial ground in the Barnaul Ob region. Analysis of a small series of mitochondrial DNA samples (N = 10) confirmed the participation of populations associated with the autochthonous genetic substrate of the southern regions of Western Siberia in the formation of the genetic composition of the Staroaleisk population (specific composition of the Western Eurasian component of the mtDNA gene pool and the presence of autochthonous Eastern Eurasian A10 haplogroup). We showed the presence of mtDNA (lineages of haplogroups A8 and A11) in the Staroaleisk population, which testifies to its genetic ties with the carriers of the Scythian-Siberian cultures who inhabited the territories to the east of the Upper Ob region – the Altai- Sayan mountain system, Tuva and adjacent regions of Central Asia. Thus, paleogenetic data indicate that the genetic composition of the Sratoaleisk population was formed under the conditions of the genetic interaction between autochthonous populations of the region, whose genetic roots go back to the Bronze Age, and newly migrated groups who were carriers of the cultural traditions of the Scythian-time nomads. Taking into account the informative value of the first genetic results, we can expect a significant detailing of ethnogenetic processes reconstructions with increasing of DNA samples from the Staroaleisk population, analysis of additional genetic markers (Y-chromosome) and obtaining data on the gene pool of other early Iron Age populations from the Upper Ob region and adjacent regions of the South Siberia.
