Echoes of Eastern Hunter‑Gatherers

When the ice retreated and forests and rivers reclaimed the plain, small bands of hunter‑gatherers pushed back into the East European landscape. Archaeological data from sites such as Dereivka I, Vasil'evka, Vasylivka-1 and -3, Karavaikha 1, and Berendeyevo (Yaroslavl) document repeated occupation from the early Holocene through the late Mesolithic (ca. 10,509–4,251 BCE). Material assemblages preserved in these riverine and floodplain contexts point to a long-standing adaptation to steppe‑forest margins: microlithic toolkits, bone implements, and locality‑specific raw material use.

Genetic sampling of 28 individuals spanning this interval suggests a population that fits broadly within the Eastern European Hunter‑Gatherer (EHG) genetic horizon. This genomic signal implies deep continuity on the East European Plain while also leaving room for contacts with neighboring groups to the north and east. Archaeological affinities with the Mesolithic Veretye traditions in parts of the Vologda region and later overlaps with Neolithic Volosovo‑Lyalovo material hint at cultural continuities and gradual local change rather than abrupt replacement.

Limited evidence constrains fine‑scale models: localized site sequences and sparse preservation mean that regional patterns are still being refined, and interpretations should be seen as provisional pending further excavation and genomic sampling.

The genetic dataset for this cultural grouping comprises 28 dated individuals from Ukraine and northwest Russia (range 10,509–4,251 BCE). Maternal lineages are dominated by haplogroup U (14/28), a pattern repeatedly associated with European Mesolithic hunter‑gatherers. Secondary mtDNA lineages (K1, T, H, and U4b) occur in smaller numbers; these suggest limited maternal diversity and potential episodic contacts with neighboring groups or later admixture events.

On the paternal side, Y‑DNA shows a plurality of haplogroups: I (6) and R (6) are the most frequent, with Q present in four individuals and single occurrences of R1b and F. The presence of Q, in particular, may reflect eastern or northeastern gene flow into the East European Plain, while the coexistence of I and R lineages is consistent with a heterogeneous hunter‑gatherer population structure. Overall autosomal profiles (contextualized by broader studies of the region) are consistent with an Eastern European Hunter‑Gatherer (EHG) component that is distinct from Western Hunter‑Gatherer (WHG) groups further west.

Because sample counts per individual site can be small even though the total is 28, local patterns should be treated cautiously. The dataset is substantial enough to support a regional portrait of EHG‑aligned ancestry, but finer inferences about migration routes and micro‑demography await additional genomes and isotopic integration.
