Древняя ДНК носителей фатьяновской и абашевской культур эпохи бронзы (к вопросу о миграциях населения эпохи бронзы в лесной полосе на Русской равнине)
Ancient DNA of the Bearers of the Fatyanovo and Abashevo Cultures of the Bronze Age (Concerning Migrations of the Bronze Age people in the Forest Belt on the Russian Plain)

Summary/Abstract: This study addresses a fundamental question of the origins and migration patterns of paleopopulations of the Fatyanovo and the Middle Volga Abashevo archaeological cultures. It is for the first time that we report a paleogenetic analysis of 14 Abashevo individuals (Pepkino and Starshy Nikitinsky sites). Besides, we analysed ancient DNA samples of 25 Fatyanovo individuals.Specifically, we performed analyses of STR marker and haplogroups of the Y chromosome, which revealed the distinct R1a (Z93) haplogroup in Fatyanovo samples. It indicates the influence of the founder effect and gene drift, confirming the hypothesis of their migrant origin. In contrast, the Abashevo culture samples are heterogenous, as we discovered 2 groups with different origins on the paternal line. To be more specific, three men from Pepkino mound are haplogroup R1b (Z2103) carriers, while seven other individuals have haplogroup R1a (Z93>Z94). In addition, close relatives with identical STR haplotypes of the Y-chromosome were identified in both Fatyanovo and Abashevo groups.The comparative analyses of autosomal markers from 19 samples and previously published data uncovered similarities between Abashevo men from Pepkino mound (the haplogroup R1a (Z93>Z94)) with the Fatyanovo people, as well as with some representatives of the Unetice culture. These results are suggestive of the genetic continuity in the Russian Plain. Yet, less recent ancestors of Abashevo group interred in Pepkino mound could have migrated from the same region as the Fatyanovo predesessors.
