interdisciplinary study of the Jomon skeletons excavated from the Kanto region of Japan

采用单核苷酸多态性分析技术对东京、千叶和长野出土的23具绳纹人骨骼的线粒体DNA进行了分析。成功分析了17个样本。观察到的单倍群及其频率与北海道和东北绳纹人相似，然而，在本研究分析的样品中仅观察到一些亚单倍群。我们的研究结果表明，绳文时代的古代日本人并不是遗传同质的。

Mitochondrial DNA of 23 Jomon skeletons excavated from Tokyo, Chiba, and Nagano were analyzed by using a newly developed single nucleotide polymorphisms analysis. Seventeen samples were successfully analyzed. Observed haplogroups and their frequencies were similar to those of Hokkaido and Tohoku Jomon people, however, some sub-haplogroups were exclusively observed in the samples analyzed in this study. Our results indicated that ancient Japanese in the Jomon era were not genetically homogeneous.
