| Outline of Final Research Achievements |
Ancient genome analysis is necessary to investigate the genetic origin of Japanese people. In this study, we tried the screening ancient human bone samples excavated from the sites located in western part of the Japanese Archipelago, from which ancient genome data have not been reported.
To extract genomic DNA from an ancient human bone, several hundreds mg of bone powder is required. To avoid such destruction of ancient human bone samples, we measured the racemization rate of aspartic acid included in collagen of bone samples at first because measuring of racemization rate can be performed using only 20 mg of bone power. We could carry out the screening of ancient bone samples without superfluous destruction, by the screening based on racemization rate.
