| Outline of Final Research Achievements |
The region around Lake Baikal in Siberia is an important area to understand the formation of Northeast Asian human populations. In this study, we applied next-generation sequencing to ancient bone and tooth specimens that were excavated from archaeological sites dated from Neolithic to Medieval periods in the Republic of Buryatia. As results, we found that Early Neolithic individuals in Buryatia had a similar genetic background with individuals of the same periods in the Cis-Baikal region. From the Late Neolithic to Iron Age, Buryatia individuals overlapped with the Early Neolithic individuals while Cis-Baikal individuals genetically shifted toward Western Eurasians. In addition, individuals of the Medieval period had a variety of origins: One was suggested to have originated from East Asia but another from Central Asia. The present study contributes to reveal the history of the peopling of Buryatia.
