Angara River Bronze Age Echoes

Along the ice‑riven course of the Angara River, Bronze Age communities left sparse but evocative traces. Radiocarbon dates from human remains recovered at Glazkovo, Sukhaja Pad' Buret', Ust'-Dolgoe, Anosovo N 1 and Podostrozhnoe N 3 cluster between 2887 and 2201 BCE, placing these individuals firmly in a Cis‑Baikal Bronze Age horizon sometimes grouped under the Angara River Bronze Age culture. Archaeological data indicates continuity with earlier Neolithic forager traditions in settlement location and subsistence emphasis on riverine resources, even as new metal objects and trade items appear in the landscape.

The genetic evidence, though limited in scale, hints at population continuity with deep East Eurasian roots: four of five male-derived Y‑chromosomes fall into haplogroup Q, a lineage widely observed across Siberia and parts of northern Eurasia. This suggests a durable paternal substrate in the Angara corridor. However, with only five samples the picture is provisional; processes such as migration, admixture, and cultural diffusion cannot be fully resolved. Limited evidence suggests these people were part of broader regional networks that connected the Baikal littoral with interior Siberia, carrying both local traditions and new Bronze Age influences.

Ancient DNA from five individuals along the Angara River yields a compact but informative snapshot. Four male Y‑chromosomes are assigned to haplogroup Q, a lineage with deep distribution in Siberia and connections to later populations across northern Eurasia and the Americas. This concentration suggests a strong paternal continuity in the local population during the Bronze Age, although the small sample size (n=5) mandates caution: patterns observed here may not represent the full genetic diversity of the region.

Mitochondrial DNA among the sampled individuals includes haplogroups F, A, D3* and C4*—maternal lineages commonly associated with East and Northeast Asia and Siberia. This maternal diversity aligns with an East Eurasian genetic background and points to long‑standing local maternal ancestry. Archaeological data combined with these genetic signals indicate the Angara corridor hosted populations with predominant Siberian genetic affinities rather than obvious influxes of west Eurasian Bronze Age ancestry during this time window. Yet, given only five samples, admixture events, heterogeneity between sites, and temporal changes remain plausible and unresolved. Future sampling across more graves and settlements will be essential to test hypotheses about mobility, kinship, and interactions inferred from these preliminary genetic patterns.
