Outline of Final Research Achievements

In this study, a total of 47 ancient genomes were analyzed (43 from the Jomon and 4 from the Yayoi skeletal remains). Phylogenetic analysis using the whole sequence data of mitochondrial DNA revealed that the Jomon people are not a genetically homogeneous population, but differ among regions. Analysis of the whole genome sequences revealed that the genetic diversity of the Yayoi people was greater than previously proposed. It was also revealed that the immigrant Yayoi people were already mixed with the indigenous Jomon people. These facts suggest that it is necessary to rethink the traditional theory of the formation of the Japanese population.
