|Abstrakt EN:||Several authors (e.g., Ruff et al., 1993; Trinkaus and Ruff, 2012) declare a decreasing robusticity trend of lower limb long bones in the genus Homo through time from the Early Pleistocene until present. This trend is usually interpreted as a consequence of decreasing levels of mobility and activity patterns, changes in lifestyle, and environmental factors. There is also evidence of increasing robusticity over the individual lifespans (Martin and Atkinson, 1977; Ruff and Hayes, 1983). Such an increase is caused by continuous bone remodeling which optimizes the structure of a bone to effectively resist mechanical loading and, at the same time, acts more progressively on the side of subperiosteal apposition than on the side of resorption. This paper is aimed at re-exploring temporal trends in robusticity of lower limb long bones within the genus Homo in the Pleistocene and Early Holocene. The principle questions tested are whether the consideration of age-at-death of Pleistocene and Holocene individuals can confound, in any way, published robusticity trends, given the fact that robusticity tends to increase over the individual lifespans.|
