从16000年前开始，新石器时代的生活方式被称为绳文文化传播到整个日本群岛。尽管考古学和体质人类学对绳纹人进行了广泛的研究，但人们对绳纹人的遗传特征知之甚少。在这里，我们报告了整个有丝分裂基因组和部分核基因组的骨骼遗骸从最初的绳文时期，是从东名贝壳垃圾场在佐贺市，九州岛，日本挖掘。这是对九州岛最早的绳纹人的第一次基因组分析。这些结果为了解绳文族的时间变迁和地域差异提供了重要的资料。线粒体DNA和Y染色体单倍型群与先前报道的晚绳纹人相似。此外，从最初到最后的绳文时期的三个核基因组的比较表明，在整个日本列岛的绳文时期的遗传连续性没有显着的证据混合。这表明绳文人的遗传分化是由绳文时代的区域化进程所促进的。进一步积累高质量的绳纹基因组数据，跨越广泛的地区和年龄将澄清绳纹人的亲密的区域和时间的差异和他们的混合历史的细节与水稻festival，绳纹线粒体基因组数据所建议的。研究结果为进一步分析提供了重要信息。
Starting 16000 years ago, the Neolithic lifestyle known as the Jomon culture spread across the Japanese archipelago. Although extensively studied by archaeology and physical anthropology, little is known about the genetic characteristics of the Jomon people. Here, we report the entire mitogenome and partial nuclear genome of skeletal remains from the initial Jomon period that were excavated from the Higashimyo shell midden site at Saga City, Kyushu Island, Japan. This is the first genome analysis of the initial Jomon people of Kyushu Island. These results provide important data for understanding the temporal transition and regional differences of the Jomon people. The mitochondrial DNA and Y-chromosome haplogroups were similar to those found in the previously reported later Jomon people. Moreover, comparison of three nuclear genomes from the initial to final Jomon periods indicated genetic continuity throughout the Jomon period within the Japanese archipelago with no significant evidence of admixture. This indicates that the genetic differentiation found among the Jomon people was promoted by the progression of regionalization throughout the Jomon period. Further accumulation of high-quality Jomon genome data spanning a wide range of regions and ages will clarify both intimate regional and temporal differences of the Jomon people and details of their admixture history with rice fanners, as suggested by Jomon mitochondrial genome data. The results obtained from this study provide important information for further analysis.
