为了调查分布在北海道北部和东部以及库页岛南部的鄂霍次克人在5世纪至13世纪的系统发育状况，从考古遗址出土的人类骨骼和牙齿遗骸中仔细提取了DNA。成功地扩增了线粒体DNA(MtDNA)控制区的高变区1序列，并从37名鄂霍次克族个体中鉴定出16种mtDNA单倍型。在发现的16个单倍型中，6个是鄂霍次克族独有的，另外10个是东北亚人共有的，目前分布在库页岛周围和阿穆尔河下游。从mtDNA序列推断的系统发育关系表明，鄂霍次克族与东北亚人群中的Nivkhi和Ulchi人的亲缘关系更近。此外，鄂霍次克族与北海道的阿伊努人有较近的遗传亲缘关系，可能是东北亚人向阿伊努人基因流动的中介。这些发现支持了之前的考古学和人类学研究表明，鄂霍次克文化加入了萨蒙文化(柔门人的直系后裔)，从而形成了阿伊努文化的假设。
In order to investigate the phylogenetic status of the Okhotsk people that were distributed in northern and eastern Hokkaido as well as southern Sakhalin during the fifth to the thirteenth centuries, DNA was carefully extracted from human bone and tooth remains excavated from archaeological sites. The hypervariable region 1 sequences of the mitochondrial DNA (mtDNA) control region were successfully amplified and 16 mtDNA haplotypes were identified from 37 individuals of the Okhotsk people. Of the 16 haplotypes found, 6 were unique to the Okhotsk people, whereas the other 10 were shared by northeastern Asian people that are currently distributed around Sakhalin and downstream of the Amur River. The phylogenetic relationships inferred from mtDNA sequences showed that the Okhotsk people were more closely related to the Nivkhi and Ulchi people among populations of northeastern Asia. In addition, the Okhotsk people had a relatively closer genetic affinity with the Ainu people of Hokkaido, and were likely intermediates of gene flow from the northeastern Asian people to the Ainu people. These findings support the hypothesis that the Okhotsk culture joined the Satsumon culture (direct descendants of the Jomon people) resulting in the Ainu culture, as suggested by previous archaeological and anthropological studies.
