Formation and metamorphosis of the Ok hotosk culture people in Sakhalin - From the view point of acculturation -

在总结了三年来的研究成果的基础上，于2月28日和3月1日召开了国际学术研讨会，并发表了会议论文集。本文得到以下五个结论：1.这是更合理的理解鄂霍次克人由两个主要群体，即十和田和Susuya-Enoura组。2.形成于库页岛西南部的十和田人，以沿海海洋适应生活方式为特征。居住在间宫海峡对岸的普里森江地区的沿海居民加入十和田组的可能性很大。Susuya-Enoura群形成于萨哈林岛东南部，以泻湖海洋适应生活方式为特征。北库页岛文化团体，接收来自北海道岛的Epi-Jomon人的移民。可能形成了这种生活方式。鄂霍次克人的牙齿非常磨损，被认为是长时间咀嚼的结果。我们仍然无法具体说明饮食习惯或使用牙齿作为工具的主要原因。5.北萨哈尔文化群和上绳文群的运动应是气候波动的结果。

Summarizing the data studied in the three years project, we had International Symposium on Feb. 28th and Mar. 1st and published it's proceedings. We got five conclusions as follows;1. It is more reasonable to understand the Okhotsk people consisted from two main groups that's of Towada and Susuya-Enoura groups.2. Towada group, formed in the south western part of Sakhalin was characterized by coastal maritime adapted life style. There is high possibility that some coastal people lived in Pri-Morie region (on the opposite bank of Mamiya Strait) joined Towada group.3. Susuya-Enoura group, formed in the south eastern part of Sakhalin was characterized by lagoon maritime adapted life style. North Sakhalin Cultural group, receiving immigrants of Epi-Jomon people from Hokkaido Isl. might formed this life style.4. The extremely worn out tooth, characteristic of the Okhotsk people is thought as a result of long time usual chewing. We still can not specify the main cause which dietary habits or using tooth as tools.5. The movements of North Sakhal in Cultural Group and Epi-Jomon Group should be caused by climatic fluctuation.
