Tashtyk culture genomics

The Minusinsk Basin in Southern Siberia had unique conditions for the development of ancient societies, thanks to its geographical location, favorable climatic conditions, and relative isolation. Located at the northern periphery of the eastern Eurasian steppe, surrounded by the Altai-Sayan Mountains this area witnessed numerous ancient human migrations with specific types of interaction between outside and local archaeological cultures.The genomic history of the human population of Southern Siberia from the Chalcolithic to the middle Bronze Age has been relatively well described in the recent genome-wide studies, while the genetic ancestry of populations, represented by diverse archaeological cultures of the Late Bronze and Early Iron Ages, remains a blank spot for modern paleogenomics.Here, for the first time, we present two ancient nuclear genomes of the individuals buried in the Oglakhty cemetery (early Tashtyk culture, 2nd to 4th centuries AD). Our pilot study is undertaken within a multidisciplinary project on this noteworthy site with well-preserved organic remains and provides fresh paleogenomic data on the ancient societies of Southern Siberia.
