Abstract

Background: The Jomon period of Japan is characterised by a unique combination of sedentary and hunting/gathering lifestyles, spanning for more than 10,000 years from the final Pleistocene to the Holocene. The transition from the preceding Palaeolithic period to the Jomon period is known to have begun with the appearance of pottery usage. However, knowledge of the genetic background of the Jomon people is still limited.

Aim: We aimed to determine the population-scale complete mitogenome sequences of the Initial Jomon human remains and compare the occurrence of mitochondrial haplogroups in the Jomon period from temporal and regional perspectives.

Subjects and methods: For human remains dated to 8200-8600 cal BP, we determined their complete mitogenome sequences using target enrichment-coupled next-generation sequencing.

Results: We successfully obtained the complete mitogenome sequences with high depth of coverage and high concordance on consensus sequences. These sequences differed by more than three bases each, except for two individuals having completely identical sequences. Co-existence of individuals with haplogroups N9b and M7a was first observed at the same archaeological site from the Initial Jomon period.

Conclusion: The genetic diversity within the population was not found to be low even in the Initial Jomon period.

日本绳纹人母系的多样性。

背景:从更新世末期到全新世，日本绳纹时代的特征是一种独特的定居和狩猎/采集生活方式的结合，持续了1万多年。众所周知，从旧石器时代到绳纹时代的过渡是从陶器的出现开始的。然而，对绳纹人遗传背景的了解仍然有限。目的:确定绳纹原始人类遗骨的全有丝分裂基因组序列，并从时间和区域角度比较绳纹时期线粒体单倍群的出现情况。研究对象和方法:对于可追溯到8200-8600 cal BP的人类遗骸，我们使用靶富集偶联新一代测序确定了他们的完整有丝分裂基因组序列。结果:成功获得了覆盖深度高、一致性高的有丝分裂基因组全序列。这些序列的差异超过三个碱基，除了两个个体的序列完全相同。在绳纹时代初期的同一考古遗址中，首次观察到个体与N9b和M7a单倍群共存。结论:即使在绳纹初期，居群内的遗传多样性也不低。
