Claim: Although scholars in the past speculated that Japanese people had a common origin in either the Yayoi or the Jōmon period, according to genetic and anthropometric studies on Japanese people, they have genetic ancestry from both, but their skulls are closer to those of the Yayoi people.
Evidence: From the point of view of genetic studies, Japanese people: skulls closer to those of Yayoi people than to those of Jōmon people. Currently, the most well-regarded theory is that present-day Japanese are descendants of both the indigenous Jōmon people and the immigrant Yayoi people.
