Salkhityn Am sits on the cusp of taiga and steppe, a place where horizons open like film reels of dust and horsehair. Archaeological data from Khuvsgul indicates human presence across the late Iron Age, and the dated DNA samples here span roughly 356–1 BCE. This timeframe overlaps the formative centuries of the Xiongnu polities that would come to dominate much of the eastern steppe.
The genetic signal in these 11 individuals suggests a tapestry woven from both western Steppe-associated ancestries and eastern Siberian lineages. Y‑chromosome types dominated by haplogroup R — often linked in other studies to West Eurasian and Steppe male lines — sit alongside Q and occasional J lineages, hinting at complex male-mediated movements and contacts. Maternal lineages are similarly mixed: European-associated I1a and U appear with East Eurasian G, F, and C4 haplogroups, indicating female lineages from both east and west.
Limited evidence suggests Salkhityn Am functioned as a nexus of mobility rather than an isolated enclave. The archaeological record and the genetic mosaic together point to the Khuvsgul region as a dynamic frontier where people, animals, and ideas flowed between forest and grassland.
Caution: with 11 genomes the picture is suggestive rather than definitive; broader sampling across nearby cemeteries and earlier/later horizons is needed to chart population change through time.
