The most well-regarded theory is that present-day Yamato Japanese are descedants from both, the Yayoi people and the various local Jōmon people. Japanese people belong to the East Asian lineages D-M55 and O-M175, with a minority belonging to C-M217 and N-M231. The reference population for the Japanese (Yamato) used in Geno 2.0 Next Generation is 89% East Asia, 2% Finland and Northern Siberia, 2% Central Asia, and 7% Southeast Asia & Oceania, making Japanese approximately ~100% East-Eurasian. Genealogical research has indicated extremely similar genetic profiles between these groups, making them nearly indistinguishable from each other and ancient samples. Japanese people were found to share high genetic affinity with the ancient (~8,000 BC) "Devils_Gate_N" sample in the Amur region of Northeast Asia.
