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.

器官和组织的三维形态分析是人类起源和人类古生物学研究的热点之一。为此，我们研制了三维测量分析系统。结果报告在以下三个部分：（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致密骨、松质骨和空气的阈值。(B)i)我们研究了黑猩猩额窦形态的个体发育和静态个体差异，并评估了与亚洲类人猿的差异。ii）我们发现，更多陆生灵长类动物的股骨被设计为在前后方向上容纳更大的弯曲强度，而树栖摆臂灵长类动物的股骨具有更大的内外侧弯曲刚度。（3）已经清楚地表明，猿类的放射状切迹和猴子的一样面向前方，关于这一特征的简单二分法似乎是有问题的。(C)我们致力于数据库，存储绳纹人口，现代日本人和史前美索不达米亚人的头骨形态信息。新的数据案例仍在收集中。
