利用工程梁理论对灵长类动物肢骨进行结构分析，可以将复杂的生物形态简化为几个易于解释的功能相关参数。获得和分析这些结构参数的几种方法，包括计算机断层扫描，多平面X线摄影，光子吸收测定法，和自动数字分析。应用这些数据解决灵长类动物适应和进化问题的例子包括改进化石物种体重的估计，调查相对前肢和后肢机械负荷（“优势”），以及研究物种内和物种间行为的更微妙差异，反映在四肢骨骼形状的变化上。此外，它表明，骨干和关节结构的综合分析可以提供信息的灵长类动物四肢骨的结构进化方面不明显的独立分析的任何类型的特征单独。
Structural analysis of primate limb bones using engineering beam theory can reduce complex biological forms to a few readily interpretable and functionally relevant parameters. Several methods of obtaining and analyzing these structural parameters are described, including computed tomography, multiple plane radiography, photon absorptiometry, and automated digital analysis. Examples of applications of these data to problems in primate adaptation and evolution include improved estimation of body mass in fossil species, investigation of relative fore- and hindlimb mechanical loadings (‘dominance’), and study of more subtle within and between species differences in behavior as reflected in variations in limb bone shape. In addition, it is shown that combined analyses of diaphyseal and articular structure can provide information on aspects of structural evolution of primate limb bones not evident from independent analysis of either type of characteristic alone.
