Northeast Asia (6,093 – 4,366 BCE): Middle Holocene — Big Salmon, Big Villages, and Deepening Pottery Traditions

Geographic and Environmental Context

Northeast Asia includes eastern Siberia east of the Lena River to the Pacific, the Russian Far East (excluding the southern Primorsky/Vladivostok corner), northern Hokkaidō (above its southwestern peninsula), and extreme northeastern Heilongjiang.

• Anchors: Amur–Ussuri terraces and levees, Okhotsk embayments, Sakhalin lagoons, Kamchatka river mouths, Hokkaidō shell-midden coasts.

Beringian Standstill and the End of a Genetic Configuration

During this interval, a subset of Proto-Amerindian Paleo-Siberians entered a prolonged phase of relative genetic isolation, often referred to as the Beringian standstill. For several millennia, these populations remained largely cut off from other Asian groups.

This isolation allowed for:

• Independent genetic drift

• Local adaptation to Arctic and sub-Arctic environments

• The emergence of distinct phenotypic variation

Importantly, this genetic configuration ceased to exist within Siberia itself soon after this period. While Proto-Amerindian groups moved eastward and eventually into the Americas, Siberia underwent further demographic transformation.

Climate & Environmental Shifts

• Hypsithermal warm maximum: dense mixed taiga, long ice-free seasons, exceptionally large salmon runs.

Subsistence & Settlement

• Large pit-house villages on raised river benches; repeated rebuilds created deep cultural layers.

• Seasonal satellite camps at anadromous fish bottlenecks, seal haul-outs, and berry patches.

Technology & Material Culture

• Diversified ceramic styles (corded/impressed), larger storage vessels; ground-stone woodworking kit; broad weir/trap systems; refined toggling harpoons.

• Dugout canoes became routine for transport and net sets; dog traction in winter travel.

Movement & Interaction Corridors

• Canoe trunklines along the Amur and Okhotsk inner coasts; Kuril–Hokkaidō “island ladder” facilitated obsidian and shell exchange.

Cultural & Symbolic Expressions

• Longhouse/pit-house clustering hints at lineage districts; feasting middens with prestige shell/bead caches; ochre and grave goods in formal cemeteries.

Environmental Adaptation & Resilience

• High-capacity storage (smoked/dried salmon, rendered oils) enabled semi-sedentary lifeways; diversified procurement (elk, nuts, waterfowl) hedged against run failure.

Transition

By 4,366 BCE, the region supported durable river–coast village systems and ceramic traditions poised for late Neolithic maritime networking.
