The distribution of traditional wild food sources in the Republic of Sakha could change significantly, affecting the diets and incomes of Indigenous rural communities who depend on them.

A long-standing hypothesis, the dual-structure model, posits that Japanese populations derive dual ancestry from indigenous Jomon hunter-gatherer-fishers and succeeding Yayoi farmers. We conduct paleogenomic analyses of people of the Jomon, Yayoi, and Kofun periods from Japanese archaeological sites. We identify a later influx of East Asian ancestry in the Kofun period and clarify that the genome of the modern Japanese population is composed of three ancestral components, proposing a tripartite model of Japanese origins.
