| Outline of Final Research Achievements |
This study aims to understand the origins of modern Japanese populations using genomic data from ancient and modern Asian populations. To this end, we generated whole-genome sequence data from skeletal remains excavated from prehistoric archaeological sites in the Japanese archipelago. We then analysed these newly sequenced data with those published data from the continent. Our analysis provides genomic evidence suggesting that modern Japanese populations have a tripartite ancestral structure derived from Jomon, Northeast Asian, and East Asian ancestry.

本研究では，自然人類学においてこれまで主流であった「日本人の二重構造モデル」をさらに発展させた，「日本人の三重構造モデル」を新たに提唱した。これらの知見は，今後日本列島に眠る膨大な遺跡出土古人骨のゲノムデータから日本人の成り立ちを探る上での基盤データとして活用されることが期待される。
