几条生物考古学研究路线已经证实，从向农业过渡开始，过去人类的下肢负荷逐渐下降。这项研究的目的是评估人类胫骨曲率是否反映了这种下降，特别强调技术变革步伐最快的时间跨度。我们的研究是第一个（1）在前后（A-P）和内外（M-L）平面中对人类胫骨应用纵向曲率分析的研究，（2）纳入了广泛的时间人口样本，包括捷克领土内的农业，城市化和工业化（从公元前2900年到公元21世纪; N = 435）的密集化时期。使用三维几何形态测量学，我们调查了胫骨前曲率镜是否假设史前和工业化社会之间的下肢负荷减少，并探讨了其在所有三个维度上的形状。结果表明，轴的前后矫直呈连续趋势。这种变直与M-L平面中的相对S形曲线加重相关。考虑到所涉及的时间尺度和已知的活动性下降现象，骨几何形状的这种适应性变化可以解释为在不同的生活条件下对胫骨的生物力学需求减少。
Several lines of bioarchaeological research have confirmed the gradual decline in lower limb loading among past human populations, beginning with the transition to agriculture. The goal of this study was to assess whether human tibial curvature reflects this decline, with a special emphasis on the time-span during which the pace of technological change has been the most rapid. Our study is the first (1) to apply longitudinal curvature analysis in the antero-posterior (A–P) and medio-lateral (M–L) planes to the human tibia, and (2) that incorporates a broad temporal population sample including the periods of intensification of agriculture, urbanization and industrialization (from 2900 BC to the 21stcentury AD; N = 435) within Czech territories. Using three-dimensional geometric morphometrics, we investigated whether anterior tibial curvature mirrors assumed diminishing lower limb loading between prehistoric and industrialized societies and explored its shape in all three dimensions. Results showed the continuous trend of A–P straightening of the shaft. This straightening was associated with a relative sigmoidal curve accentuation in the M-L plane. Given the timescale involved and the known phenomenon of declining mobility, such adaptive changes in bone geometry can be interpreted in terms of the diminishing biomechanical demands on the tibia under different living conditions.
