[Seminar] Genomic origins of Yaponesians, people on Japanese Archipelago by Professor Naruya Saitou


Thursday, January 31, 2019 - 15:00 to 16:00


C700, Level C, Lab3



People reached Yaponesia (Japanese Archipelago) around 40,000 years ago for the first time, and many waves of migration occurred after that time. Within this framework, we seek to decipher the genomic history of Yaponesians (people on Japanese Archipelago) through determination and comparative analyses of many modern and ancient human genomes. We also analyze genome data of animals and plants which moved to Yaponesia with Yaponesians. Temporal changes of population size are also estimated from genome sequence data by using existing methods and newly developed methods. Because we need to examine history of Yaponesians from many aspects, archeology with special reference to age estimation (dating) of artifacts and ancient organisms and linguistics with special reference to dialect analyses of Japanese and Ryukyuan languages will have collaborative fusion study with evolutionary genomics. We aim to establish new discipline, “genome history” of Yaponesians, through integration of these various analyses.
