The purpose of this study is to determine whether histologic skeletal development in chimpanzees (Pan troglodytes) differs from that in humans. Currently, minimal quantitative data are available on the bone histology of great apes. In addition to providing baseline data on juvenile chimpanzee bone histology, the data generated by this study have potential applications for studying the comparative development between chimpanzees and humans and other primates, as well as investigating the evolution of human bone development, differences in development among limb elements, and differences in histology related to locomotor function. The study sample includes thin sections from the femoral, tibial, and fibular midshafts of 13 chimpanzees originally prepared by Kerley ([1966] Tulane Stud. Zool. 13:71-82) as part of a study on skeletal age changes in the chimpanzee. Twelve juveniles, ranging in known age from 2-15.3 years, and one adult, with a known age of 35 years, are represented. For each specimen, numbers of osteons, osteon fragments, and non-Haversian canals were counted, and percent lamellar bone was estimated. Results were compared with data extracted from Kerley ([1965] Am. J. Phys. Anthropol. 23:149-164) on a juvenile human sample. Results indicate that juvenile chimpanzees and humans exhibit similar age-related changes in histologic variables. However, age is not as strong a predictor of variation in microstructural variables in chimpanzees as it is in humans.
本研究的目的是确定黑猩猩（Pan troglodytes）的组织学骨骼发育是否与人类不同。目前，关于大猩猩骨骼组织学的定量数据极少。除了提供幼年黑猩猩骨骼组织学的基线数据外，本研究产生的数据在研究黑猩猩与人类及其他灵长类动物之间的比较发育、调查人类骨骼发育的演变以及四肢骨骼发育差异和与运动功能相关的组织学差异方面具有潜在应用价值。研究样本包括13只黑猩猩股骨、胫骨和腓骨骨干的薄片，这些薄片最初由Kerley制备（[1966]《杜兰大学动物学研究》13:71 - 82），作为黑猩猩骨骼年龄变化研究的一部分。样本中有12只已知年龄在2至15.三岁之间的幼年黑猩猩和1只已知年龄为35岁的成年黑猩猩。对每个标本，计数骨单位、骨单位碎片和非哈弗斯管的数量，并估算板层骨百分比。将结果与从Kerley（[1965]《美国体质人类学杂志》23:149 - 164）提取的人类幼年样本数据进行比较。结果表明，幼年黑猩猩和人类在组织学变量上表现出相似的年龄相关变化。然而，年龄对黑猩猩微观结构变量变化的预测能力不如对人类的预测能力强。
