| Research Abstract |
Individual identification of ancient human remains is one of the most fundamental requisites for studies of palaco-population genetics including kinship among ancient people, intra-and inter-population structures in ancient times, and the origin of human populations. However, knowledge of these subjects has been based mainly on circumstantial archacological evidence for kinsip and intra-population structure and on genetic studies of modern human populations. Here 1 performed individual identification of ancient humans using short-nucleotide tandem repeat and mitochondrial DNAs as genetic markers. The application of this approach to kinship analysis showed clearly the presence or absence of kinship among the ancient remains examined. furthermore, I determined nucleotide sequence data of mitochondrial DNA of ancient Japanese of "Yayoi" cra using skeletons excavated from the Takuta-Nishibun site. This site located on the northern Kyushu shows a diversity in burial type of human remains. Nucleotide sequnces of the major non-coding region of the mitochondrial DNA are determined from the 26 "Yayoi" individuals. Nucleotide sequence diversity shows that the "Yayoi" people of the Takuta-Nishibun site is not a genetically isolated population. Phenetic tree analysis indicates a statistically significant corrclation between burial type and genetic background of the Takuta-Nishibun individuals, and shows no discrete pattern clustering the "Yayoi" people or the "Jomon" people and carly modern Ainu.
