Devil's Gate Neolithic Echoes

The people sampled from Devil's Gate Cave (Devil's-Gate-Cave, Dalnegorsk municipality, Primorsky Krai) lived during the early Neolithic, with radiocarbon-dated remains spanning roughly 5830–5481 BCE. Archaeological data indicates repeated cave occupation along a temperate, riverine-to-coastal landscape. Stone tools, hearth features and faunal assemblages suggest a mobile economy oriented to fishing, shellfish and small-game resources rather than intensive agriculture.

Cinematic in its immediacy, the site captures a marginal yet productive littoral zone where human groups exploited tidal flats and river mouths. Limited evidence suggests regional connections across the Amur–Primorye corridor: material parallels link local lithic traditions and subsistence strategies to contemporaneous communities across northeastern Asia. Given only seven genetic samples, any narrative of arrival or population replacement must remain cautious. The archaeological record situates these people within a broader Neolithic mosaic of hunter-fisher groups adapting to rich coastal environments rather than large-scale agrarian transformations.

Seven genetic samples from Devil's Gate Cave offer an intimate but small window into early Neolithic ancestry in the Russian Far East. Maternal lineages are dominated by mtDNA D4 (4 individuals) and D4m (3 individuals), a cluster of haplotypes widely observed in ancient and modern populations of Northeast Asia and the adjacent islands. Y-chromosome data are sparse: one individual carries haplogroup C, a lineage present in multiple ancient East Asian and Siberian contexts and among several modern groups.

The mtDNA signal suggests strong maternal continuity in this coastal region through the Holocene, consistent with archaeological impressions of long-term exploitation of regional marine resources. However, with only seven samples (<10), patterns of genetic diversity, sex-biased mobility or gene flow from inland or island populations remain preliminary. Archaeogenomic comparisons hint at affinities between these individuals and other Northeast Asian hunter-fisher groups, but the limited sample count precludes firm claims about demographic processes such as migration, admixture, or population continuity.

Future, larger datasets are needed to resolve whether the Devil's Gate profile reflects a local enduring population, seasonal aggregation of related groups, or broader regional networks across the North Pacific edge.
