颅骨形态的区域间比较研究依赖于根据作者选择的标准构建的复合标本。虽然有许多关于所谓的“绳纹种群”内部变异的报告，但很少有人讨论区域分类的有效性问题。在这项研究中，Mahalanobis'D2的计算从度量和非度量数据，以评估绳文颅骨的区域内和区域间的变化，主要来自两个地区的北方千叶和厚见半岛。根据D2s和Bootstrap概率，两个地区的样本不能被视为一个具有形态特征的同质单元。区域内变化的非均匀性与区域间变化的非均匀性一样大。这可能表明，至少在本研究所用的样本中，形态差异与区域差异并不平行，因此，对于所谓的“绳纹种群”，区域分类是无效的。
Inter-regional comparative studies of cranial morphology depend upon composite specimens constructed according to the standards chosen by the writers. Although there have been many reports about variations within the so-called "Jomon population ," very few have taken up the issue of the validity of the regional classification. In this study, Mahalanobis' D2s are calculated from metric and nonmetric data to evaluate the intraand inter-regional variation of Jomon crania, mainly from two regions northern Chiba and the Atsumi Peninsula. The samples of both districts cannot be regarded as a homogeneous unit with morphological peculiarity by the D2s and bootstrap derived probabilities. The heterogeneities of the intra-regional variation are as large as those of inter-regional variation. This may indicate that, at least in the samples used for this study, morphological differences are not parallel to regional ones and thus, for what has been called the "Jomon population ," the regional classification is not valid.
