Forest Neolithic — Upper Volga

The Forest Neolithic unfolds across lake basins and river valleys of northern Russia between the mid‑7th and early 4th millennium BCE. Archaeological sites included here—Sakhtysh‑2, Sakhtysh‑2a, Sakhtysh‑8 (Ivanovo Oblast), Afontova‑Gora and Dolgoye‑Ozero (Krasnoyarsk Krai), Ust'-Isha (Altai Krai), Yazykovo (Ulyanovsk Oblast), Kumyshanskaya Cave (Sverdlovsk Oblast) and Zamostye‑2 (Moscow Oblast)—preserve house traces, pottery, and burials that link coastal lakeside economies with forest resources.

Material culture shows affinities to the Volosovo and Lyalovo traditions: fine tempered pottery, polished stone tools, and ritualized burials with ochre. Limited evidence suggests these communities emerged from Mesolithic hunter‑gatherers who increasingly adopted local Eneolithic practices along the Volga‑Oka axis. Archaeological data indicates episodic contact with northern Ural and West Siberian networks, reflected in decorative styles and raw material movement.

The cinematic landscape—peat bogs, birch‑pine forests and slow rivers—shaped lifeways and mobility. Although the archaeological record is regionally uneven, the combined site assemblage demonstrates a persistent forest‑zone adaptation spanning millennia.

Twenty‑six genomes sampled from Forest Neolithic sites provide a rare window into demographic history. Maternal lineages are dominated by mtDNA U (22/26), a hallmark of European and Siberian Mesolithic populations, suggesting strong maternal continuity with pre‑farming hunter‑gatherer groups across northern Eurasia. Two Z1, one K and one A+ further indicate occasional inputs from northern Siberian and wider Eurasian pools.

Y‑chromosome data are reported for a subset of individuals (counts sum to ~20). Haplogroup R is the most frequent (≈10), with I (≈4) also present—elements often associated with European hunter‑gatherer and early Holocene groups. The presence of Q (≈3) and C (≈2) points to links with Siberian and northern Eurasian paternal ancestries. A single F signal hints at rarer eastern affinities. Because Y‑data come from a subset of remains, interpretations about paternal structure are preliminary.

Combined, the genetic picture paints a community with deep Mesolithic maternal roots and a mixed paternal heritage: predominantly local European/forest‑zone lineages with measurable Siberian connections. Limited sample sizes for some haplogroups advise caution: the patterns are suggestive but not definitive, and future sampling may refine these signals.
