Y-chromosome analysis of Bronze Age populations from the territory of present-day Poland
Abstract:
The Bronze Age in the area of what in the present-day makes Poland lasted for more than a dozen centuries (2300-700 BC). At that time, this territory was inhabited by various groups of different origins, as well as of different levels of economic and social development. Finally, around 1350 BC, the Lusatian culture emerged amidst this heterogeneous cultural background. Some researchers in the past associate the people of the Lusatian culture with the Proto-Slavs.The aim of this study was to determine the origin and genetic structure of male lineages from the Mierzanowice culture (2300-1600 BC), the Trzciniec culture (1900-1000 BC) and the Lusatian culture (1350-400 BC), which occupied the territory of the present-day Poland using the Y-chromosome-wide SNPs. The analysis of the Y chromosome variation made it possible to test for the continuity of settlement in the mentioned area throughout the Bronze Age and for a possibility of a connection between the Lusatian culture and the younger Iron Age populations. The analysed material consisted of skeletal fragments collected from 46 Bronze Age individuals. The samples with more than 1% of endogenous DNA, after sex determination, were subjected to targeted enrichment with a custom in-house-designed panel of 10k Ychromosome SNPs and/or with myBaits Expert Human Affinities Prime Plus. The Y-chromosome haplogroup was determined for 25 individuals. Most of the Bronze Age individuals belonged to R1a haplogroup subclades. There were also individuals belonging to haplogroup I2a and O2a-L465. The lack of these Y-chromosome lines identified in the younger Iron Age samples suggests at least some level of discontinuity with the Bronze Age populations. The research is part of the project „Genetic history of Poles” (2018/31/B/HS3/01464) financed by the National Science Centre, Poland.
The crossroad of Europe. Ancient genomes from Poland tell the story of where the West meets the East
Abstract:
Central Europe has long been a European a sort of a cauldron of human populations. The Great European Plain conferred little resistance to movements of larger groups, be it for trade, settlement or warfare, hence providing ground for intense genetic exchange. However, due to hitherto limited paleogenomic research in this region, the timing, direction and intensity of gene flow that has shaped the population of the Vistula and Oder River basins remains largely unexplored and has mostly been inferred from the modern genetic variation. Moreover, the custom of cremating the dead, spread among many cultures from this region between the Bronze Age and the Early Medieval, along with the prevalence of sandy soils accelerating bone decomposition, resulted in significant temporal and geographical patchiness of the skeletal record available for genetic analyses. Our project aims at retrieving genetic data for possibly comprehensive representation of the population of the region throughout space and time to assess the level of genetic continuity as well as the timing and direction of gene flow into and within. By the time of this abstract submission, we had collected remains of over 500 individuals dating to between the Neolithic and Modernity, including several from the subregions and periods in which non-cremated burials are a rarity. We genotyped over 120 of the individuals, and our dataset is being continuously expanded. We performed population genomic analyses based on i.a. F-statistics and IBD sharing, which allowed us to test several hypotheses based on the available archaeological context and historical sources. The data we obtained not only inform the “big picture” of the genetic history of “Poles” but also provide information to several interesting case studies such as familial relationships within the archaeocommunities, or genetic affinities of some distinctive burials.
