Riverborn: Early Neolithic Amur Voices

Along the wide, mist-wreathed channels of the Amur River, people reshaped life in the millennia after the last Ice Age. Radiocarbon-dated human remains placed between 8175 and 6831 BCE anchor this Early Neolithic horizon in the lower Amur Basin of northeastern China. Archaeological data indicates a transition from highly mobile post-glacial foraging to more river-oriented subsistence: pottery fragments, hearths, and concentrations of fish bone point to the long-term exploitation of salmon, sturgeon and other riverine resources.

Limited evidence suggests these communities lived in small seasonal aggregation sites rather than large permanent villages. Stone and bone tools recovered in the region are consistent with fishing, hide working, and woodworking. Comparisons with Near-Neolithic assemblages across the Sea of Japan and inland Siberia hint at cultural interactions across northern East Asia, but the material record remains sparse.

Genetic data from four sampled individuals provide a new dimension to this picture, offering snapshots of biological ancestry at precise times. With only four genomes, broad narratives must remain cautious; nonetheless, the combined archaeological and genetic view evokes a resilient riverine lifeway rooted in deep northern East Asian lineages and shaped by the ecological pulse of the Amur.

The genetic snapshot from the Amur River Early Neolithic is tantalizing but preliminary: only four individuals have been reported from 8175–6831 BCE. Among them a single male carries Y-chromosome haplogroup P (one observation), while mitochondrial lineages recorded include D4m, R11, G, and D. These mtDNA haplogroups are all part of northern East Asian maternal diversity—D and sublineages of D4 are widespread in modern Northeast Asia, G is frequent in Siberia and adjacent regions, and R11 occurs at low frequency in East Asia.

Y-haplogroup P is a deep Eurasian lineage that, in broader phylogenies, sits ancestral to branches found far to the west and east; its presence here—recorded in a single individual—should be treated cautiously and may reflect an early northern Eurasian paternal lineage contributing to later regional diversity. The maternal profiles, taken together, are consistent with long-term continuity of northern East Asian mitochondrial ancestry in the Amur corridor.

Archaeogenetic patterns tentatively link these Early Neolithic Amur individuals to later populations of the region (including groups sampled in historic and modern times), suggesting continuity in at least parts of the maternal gene pool. However, with n=4, stochastic sampling can mislead: additional genomes, especially from multiple sites and times, are needed to resolve population structure, sex-biased processes, and interactions with neighboring Siberian and coastal groups.
