The analysis of three-dimensional morphologies of the organs and tissue is one of the current topics in the human origin and human paleobiological researches. We develop three-dimensional measuring-analyzing system for this purpose. Results are reported in the following three sections; (A)system development, (B)applied studies, (C)database.(A) We developed an algorithm to determine the thresholds for the compactum, cancellous bone, and air.(B)i) We studied the ontogenetic development and static individual variation of the frontal sinus morphology in chimpanzees, and evaluated differences from those in the Asian great ape. ii)We found that the femora of more terrestrial primates were designed to accommodate a greater bending strength in the anteroposterior direction while those of arboreal arm-swinging primates have a greater mediolateral bending rigidity. iii)It has been made clear that the radial notch in the apes was faced anteriorly as those in monkeys, and that the simple dichotomy concerning this trait seemed problematic.(C) We worked on the database that stored morphological information of the crania of Jomon populations, modern Japanese, and prehistoric Mesopotamians. New data cases are still being collected.

对器官和组织的三维形态的分析是人类起源和人类古生物学研究的当前主题之一。为此，我们开发了三维测量分析系统。结果在以下三个部分中报告； （a）系统开发，（b）应用研究，（c）数据库。（a）我们开发了一种算法来确定压缩，取消骨骼和空气的阈值。（b）i）我们研究了个体遗传学发展和静态黑猩猩额窦形态的个体变异，并评估了与亚洲大猿的差异。 ii）我们发现，设计了更多的陆地灵长类动物的股骨，以适应前后方向的更大的弯曲强度，而树木托动臂的灵长类动物的股骨则具有更大的中外侧弯曲刚度。 iii）已经明确表明，猿类中的径向缺口是在猴子中的前方面对的，并且与这种特征有关的简单二分法似乎有问题。人群，现代日本和史前美索不达米亚人。仍在收集新的数据案例。
