The proportional relationships among the lengths of main limb bones comprising the humerus, radius, tibia and femur of the Jomon people are examined by means of comparison with those of the Kofun and recent Japanese. The disto-proximal indices (the radio-humeral and tibiofemoral) of the Jomon are significantly greater than those of the comparison ages, but the humero-femoral index, as a intermembral, is significantly smaller. Logarithmic plots showing the relation between each two bones, indicate no significant age differences among the inclinations of regression lines corresponding to allometry coefficients. However, significant age differences among the levels of lines were found. According to previous studies, there may be two factors affecting the proportions among limb segments, one biomechanical and the other thermal. The adaptation to mode of life, such as hunting of quick moving animals, appears to be a more reasonable interpretation of the relatively long distal segments (high disto-proximal indices) of the Jomon people.
通过与古坟时代及近代日本人的比较,研究了绳文人肱骨、桡骨、胫骨和股骨等主要四肢骨骼长度之间的比例关系。绳文人的远端-近端指数(桡骨-肱骨和胫骨-股骨)显著高于对照年龄组,但作为肢间指数的肱骨-股骨指数则显著较小。表示每两块骨头之间关系的对数图显示,对应于异速生长系数的回归线斜率在各年龄组之间没有显著差异。然而,发现各线水平之间存在显著的年龄差异。根据先前的研究,可能有两个因素影响肢体节段的比例,一个是生物力学因素,另一个是热因素。对生活方式的适应,如捕猎快速移动的动物,似乎是对绳文人相对较长的远端节段(高远端-近端指数)更合理的解释。
