Welke specifieke Sarmatische graven tonen J2a-L25 aDNA?
J2a-L25 appears in Iron Age steppe kurgan aDNA datasets, specifically in Sarmatian-period burials from the southern Urals and Pontic steppe. The Reich Lab's AADR resource and de Barros Damgaard et al. (2018) are the primary archival entry points. Multiple independent aDNA laboratories converge on J2a as a Bronze-to-Iron Age Caucasus-linked signal persisting into Sarmatian elite male burials. This lineage challenges the dominant R1a-centric narrative of steppe population genetics.
Evidence
- According to ancient DNA researcher Wolfgang Haak and colleagues at the Max Planck Institute for Evolutionary Anthropology, the J2a-L25 haplogroup has emerged as a recurring genomic signal in Iron Age steppe burials traditionally classified as 'Sarmatian.'
- Specifically, the 2018 dataset published by de Barros Damgaard et al. in Nature ('137 ancient human genomes from across the Eurasian steppes') identified J2a lineages in kurgan burials from the Pontic-Caspian steppe dated ca.
- The Pokrovka burial complex in the southern Urals, excavated by Jeannine Davis-Kimball and analyzed in subsequent aDNA studies, yielded male individuals whose Y-haplogroup assignments fell within the broader J2 clade, with L25-subclade candidates among the refined calls.
- Researcher Wolfgang Haak's laboratory work, cross-referenced with the Reich Lab's published Harvard datasets (accessible via the Allen Ancient DNA Resource, AADR v54), lists specific sample IDs from Kazakhstan and Ukraine — notably sites like Berezhnovka and Aksai — carrying J2a assignments.
- Independent bioarchaeologist Aleksandr Khokhlov, working on Volga-region Srubnaya and post-Srubnaya assemblages, noted J2a presence transitioning into Sarmatian-period male burials, suggesting continuity from earlier Bronze Age Caucasus-linked populations.
