长腿小关节：纳莱迪人的运动能力。

纳莱迪人的下肢呈现出一系列原始的、衍生的和独特的形态特征，这些特征对该物种两足运动的本质提出了有趣的问题。纳勒迪人所有骨骼元素的独特表现使其成为使用现代运动学软件进行步态动力学生物力学分析的绝佳候选者。然而，虚拟步态分析软件需要整个下肢运动链的3D模型。没有一个纳勒迪人保存了所有的下肢元素，保存下来的材料都是零碎的。作为未来运动学分析的前提，我们从不同纳勒迪人最完整的化石骨骼中重建了一个3D下肢骨骼。由于使用了幼年和成年的纳勒迪人，我们在类人猿（N = 143）和现代人（N = 70）的样本中测试了膝关节在整个个体发育过程中是否保持一致。重建和随后的比较分析显示，与他们的体型相比，H. naledi的关节尺寸非常小，胫骨超长，脚指数很高（90.2）。我们认为，H. naledi的下肢形态可能改善了运动经济性，但异常小的关节使人怀疑其长距离旅行的能力，包括耐力跑。纳莱迪人的原始特征和衍生特征的不同寻常的混合仍然很有趣，这可能表明这种古人类既可以用两足行走也可以攀爬，这表明古人类的运动多样性一直持续到中更新世。

期刊介绍： Journal of Anatomy is an international peer-reviewed journal sponsored by the Anatomical Society. The journal publishes original papers, invited review articles and book reviews. Its main focus is to understand anatomy through an analysis of structure, function, development and evolution. Priority will be given to studies of that clearly articulate their relevance to the anatomical community. Focal areas include: experimental studies, contributions based on molecular and cell biology and on the application of modern imaging techniques and papers with novel methods or synthetic perspective on an anatomical system. Studies that are essentially descriptive anatomy are appropriate only if they communicate clearly a broader functional or evolutionary significance. You must clearly state the broader implications of your work in the abstract. We particularly welcome submissions in the following areas: Cell biology and tissue architecture Comparative functional morphology Developmental biology Evolutionary developmental biology Evolutionary morphology Functional human anatomy Integrative vertebrate paleontology Methodological innovations in anatomical research Musculoskeletal system Neuroanatomy and neurodegeneration Significant advances in anatomical education.
