Ancient East Asian

Jōmon people

The Jōmon represent the indigenous population of the Japanese archipelago during the Jōmon period. They are inferred to descend from the Paleolithic inhabitants of Japan. Genetic analyses on Jōmon remains found them to represent a deeply diverged East Asian lineage. The Jōmon lineage is inferred to have diverged from Ancient East Asians before the divergence between Ancient Northern East Asians (ANEA) and Ancient Southern East Asians (ASEA), but after the divergence of the basal Tianyuan man, Xinyi lineage, and Hoabinhians. Beyond their broad affinity with Eastern Asian lineages, the Jōmon also display a weak affinity for Ancient North Eurasians (ANE), which may be associated with the introduction of microblade technology to Northeast Asia and Northern East Asia during the Last Glacial Maximum via the ANE or Ancient Paleo-Siberians. Other studies find ANE ancestry in Jōmon to be unlikely.
