Along the wide, ice-aged corridor of the Lena River, small groups established seasonal and perhaps year-round camps between 4343 and 2678 BCE. Archaeological data indicates burial deposits at sites such as Onnyos, Korkino, Makarovo site‑1 and Makrushyno, each providing a fragmentary but evocative record: skeletal remains, flaked stone and bone implements, and occasional organic impressions. The landscape—boreal forests, floodplain wetlands and braided channels—favored a mixed economy of fishing, aquatic resource use and targeted hunting.
Genetically, four analyzed individuals provide a slender thread linking these communities to broader East Eurasian populations. Radiocarbon dates place the assemblage in the middle to late Neolithic of Siberia, a period of regional diversification rather than mass migration. Limited evidence suggests local continuity of human groups along the Lena, with cultural practices adapted to the riverine environment.
Because the sample size is small (n = 4), any reconstruction of origins must remain cautious. These individuals hint at persistent river corridor populations that participated in wider networks across Cis‑Baikal and far‑northern Eurasia, but the archaeological and genetic signals are preliminary and patchy. Future sampling could clarify whether these sites represent a connected cultural horizon or distinct local groups.
