Nakazuma Jomon Human Skeleton 合葬

项目摘要

Approximately one hundred skeletal individuals dating the Jomon period were found from one small burial pit at the Nakazuma shell mound site, located in Toride City, Ibaragi Prefecture. The cultural remains suggests that these human skeletons were collectively reburied at the same time during Horinouchi 2 stage in the early Late Jomon period. Thus reburied people might belong to one community consisting of several families.Therefore, kinship was analyzed by comparing similarities of tooth size proportion. Twenty nine individuals were available for this analysis, and Q- mode correlation coefficients were calculated in all pairs of samples using their six or seven tooth crown measurements. Forty six pairs showed high values (more than 0.7), estimating close similarity of tooth size proportion in each pair. Consequently, it was implied that these pairs with such high values have close kinship respectively.However the reliability of kinship seems to be lower than expected, because the highly valued pairs may contain not a few accidental resem-balances. In order to estimate more reliable kinship, therefore, cluster analysis was performed including 63 Jomon individuals from other several sites in Kanto districts. As a result, the 29 Nakazuma samples examined were classified into five clusters. Among them, only the individuals belonging to two clusters fairly tied each other, suggesting kinship in each cluster. Accordingly, it was presumed that the buried people contains at least two major lineages of family.Customary tooth (UI2) evulsion was found in five of the 29 samples. Through kinship analysis above mentioned, strong kinship was not found between the five and other Nakazuma samples, hypothesizing that customary tooth evulsion was carried out against marriage from other tribe.

在位于茨城县托里德市的中妻贝壳堆遗址的一个小土坑中，发现了大约100具绳文时代的骨骼。文化遗迹表明，这些人类骨骼在绳文时代晚期早期的堀之内2阶段同时被集体重新埋葬。因此，重新埋葬的人可能属于一个由几个家庭组成的社区，因此，通过比较牙齿大小比例的相似性来分析亲属关系。29个个体可用于该分析，并且使用他们的六个或七个牙冠测量值在所有样本对中计算Q模式相关系数。46对显示高值（大于0.7），估计在每对牙齿大小比例的密切相似性。因此，这意味着这些具有如此高价值的对分别具有密切的亲属关系，但亲属关系的可靠性似乎低于预期，因为高价值对可能包含不少偶然的平衡。因此，为了估计更可靠的亲缘关系，进行聚类分析，包括63个绳纹个人从其他几个地点在关东地区。结果，检查的29个Nakazuma样本被分为五个聚类。其中，只有属于两个集群的个体彼此相当地联系，这表明每个集群中的亲属关系。在29个样本中，有5个样本存在习惯牙（UI 2）拔除。通过上述亲缘关系分析，发现这五个样本与其他Nakazuma样本之间没有很强的亲缘关系，推测拔牙是针对其他部落的婚姻而进行的。
