Cross-sectional geometric analysis of the early Middle Pleistocene human tibia from Boxgrove, West Sussex, U.K. reveals a mosaic pattern relative to other archaic Homo tibiae. The specimen has relatively low percent cortical area within its cross sections. However, it exhibits the high mediolateral strength characteristic of archaic Homo tibiae. Scaled solely to tibial length it is robust, similar to those of the Neandertals and above those of early modern and pre-Late Pleistocene African and Asian humans. However, given ecogeographically-patterned variance in relative tibial length and body laterality, it is most likely that it exhibits a level of robusticity within the range encompassed by Late Pliocene to Late Pleistocene archaic Homo combined with arctic body proportions. Given its association with late interglacial cool temperate climatic indicators, the inferred body proportions of the Boxgrove hominid were probably promoted by their minimal level of cultural buffering, requiring a significant biological conservation of body heat.
对来自英国西萨塞克斯郡博克斯格罗夫的中更新世早期人类胫骨进行的横截面几何分析显示，与其他古人类胫骨相比，其呈现出一种镶嵌模式。该标本横截面内的皮质面积百分比相对较低。然而，它展现出了古人类胫骨典型的较高的内外侧强度特征。仅按胫骨长度比例衡量，它较为粗壮，与尼安德特人的胫骨相似，高于早期现代人类以及晚更新世之前的非洲和亚洲人类的胫骨。然而，考虑到相对胫骨长度和身体侧向性的生态地理模式差异，它很可能展现出上新世晚期到晚更新世古人类所涵盖范围内的粗壮程度，并具有北极地区的身体比例特征。鉴于其与晚间冰期凉爽温带气候指标的关联，博克斯格罗夫原始人类的推断身体比例可能是由于其最低程度的文化缓冲所促成的，这需要通过显著的生物方式来保存身体热量。
