The archipelago nation of Japan has been occupied since the Upper Paleolithic period (36,000 BC), and dual genomic Japanese ancestry has been the dominant theory, up until now. A new study carried out by Trinity College Dublin, published in the journal Sciences Advances , has completely changed this narrative, pointing to a tripartite Japanese ancestry, i.e., genetic origins from three different, ancient populations.
"We are very excited about our findings on the tripartite structure of Japanese populations. This finding is significant in terms of rewriting the origins of modern Japanese by taking advantage of the power of ancient genomics," said Professor Shigeki Nakagome, a geneticist at Trinity College Dublin, and co-lead author of the study.
