Genetic Genealogy & Ancient DNA (TITLES/ABSTRACTS)

[old europe]

Abstracts of the 8th Baltic Genetics Congress, March 2023 "The limited available data for Eastern Europe suggest that demographic processes here may differ substantially from the better-studied western part. To fill the existing gap in the available ancient DNA material from Eastern Europe and contribute to a better understanding of regional human history, we sequenced aDNA from people dating over a time interval of approximately 5000 years (from the first half of the eighth millennium BC to 2500 BC) from the present-day territory of Belarus. We found that the oldest sample from the territory of Belarus had an eastern HG-like (EHG) origin, while the genetic origin changes to western HG-like (WHG) or takes the intermediate form of WHG/EHG in analyzed individuals from subsequent periods (up to 3000 BC). . Individuals dating between 3000-2500 BC had ancestors typical of both Early European Farmers (EEF) and Late Neolithic European populations. Overall, our data (1) extend the spatial range of EHG ancestry westward compared to what was previously known, (2) indicate either a complex genetic structure in Late Stone Age populations in Eastern Europe or suggest multiple waves of migration that resulted in ancestral mixing, and (3) support the spread of EEF-like ancestors northeastward to present-day Belarus." - Translated with DeepL.com
