“Human walking entails coordinated out-of-phase axial rotations of the thorax and pelvis. A long-held assumption is that this ability relies on adaptations for trunk flexibility present in humans, but not in chimpanzees, other great apes, or australopithecines. Here we use three-dimensional kinematic analyses to show that, contrary to current thinking, chimpanzees walking bipedally rotate their lumbar and thoracic regions in a manner similar to humans. This occurs despite differences in the magnitude of trunk motion, and despite morphological differences in truncal ‘rigidity’ between species. These results suggest that, like humans and chimpanzees, early hominins walked with upper body rotations that countered pelvic rotation. We demonstrate that even if early hominins walked with pelvic rotations 50% larger than humans, they may have accrued the energetic and mechanical benefits of out-of-phase thoracic rotations. This would have allowed early hominins to reduce work and locomotor cost, improving walking efficiency early in hominin evolution” (read more/open access).

“The interpretation of handaxe shape is one of the most prominent questions in Acheulean archaeological studies.Nowhere is this question as sharply defined as in Britain, where there are a number of distinct handaxe shape types. Recently reduction intensity has come to the fore as an explanation for the creation of different biface shapes, however many Acheulean researchers do not see compelling evidence for differential reduction at their sites. In this study we report an experiment in which knappers, naïve as to the goal of the experiment, reduced handaxes according to different protocols. Changes in shape and flake scar density were recorded as reduction progressed. These trajectories of shape change are compared to those seen at five British Acheulean sites: Boxgrove, High Lodge, Hitchin, Swanscombe, and Broom. Our results show that although there is evidence for differential reduction intensity at these sites, this did not have a strong influence on shape. Reduction was never exhaustive, suggesting that the life history of these tools was short. Temporally and spatially variable traditions are a better fit for the observed patterns of shape variation” (read more/open access).
