Genomes Across Japan Reveal Traces of Neanderthal and Denisovan DNA — and a Hidden Third Ancestry
A genetic study has revealed a potential third ancestral group in the DNA of modern Japanese populations. This finding challenges the long-standing two-origin model and supports the theory of tripartite origins. The research highlights distinct ancestry patterns across different regions of Japan, including traces of Neanderthal and Denisovan DNA.
- ▪The study analyzed the genomes of over 3,200 people across Japan.
- ▪Okinawa showed the strongest traces of Jomon ancestry, while western Japan had closer ties to mainland East Asia.
- ▪The research identified 44 archaic DNA regions in modern Japanese populations, linked to various health conditions.

A third ancestral group may be hiding inside the DNA of modern populations in Japan. A genetic study found the ancestry of people in Japan today may not fit into the long-standing two-origin model as once thought.After analyzing the genomes of more than 3,200 people across Japan, evidence of a third ancestral component linked to northeastern Asia alongside the Indigenous Jomon hunter-gatherers and later East Asian migrants was found.Published in Science Advances, the study used whole-genome sequencing to examine DNA from seven regions stretching from Hokkaido to Okinawa.
