reconstruction and virtual imaging techniques, this study has finally been possible,” he adds. “In this research, it has been possible to reconstruct the virtual 3D rib cage of the Turkana young man, and it has been possible to predict his adult thoracic shape,” explains García Martínez. “In addition, the shape of their rib cage was compared with that of modern humans and that of a Neanderthal individual, to investigate the movement of their breathing through virtual animation”, indicates the CENIEH researcher. The new image shows that this human species had a large lung capacity, superior to that of modern humans and similar to that of Neanderthals. This study also addresses the fact that our modern body shape may be linked to optimized

respiratory kinematics for long-distance running, as well as for Nepal Phone Number List other endurance activities. ” H. erectus may not have been the lean, athletic long-distance runner we envisioned,” Bastir notes. “In fact, this is consistent with some estimates of body weight for H. erectus , which propose that this species was heavier than previously thought. This iconic ancestor probably looked a little less like us than we portrayed him over the years. ” A body shape adapted to the environment The evolution of the human body shape reflects the way in which human ancestors adapted to the environment in which they lived. Modern humans, H. sapiens , have a relatively tall and slender body that contrasts with the body shape of Neanderthals, who are shorter and stockier.
Scientists have traditionally assumed that the modern body shape originated with the first representatives of H. erectus in the context of climatic changes related to the recession of the African rainforest, about two million years ago. Modern tall and slender bodies could be evolutionarily advantageous in the dry savanna climate that East Africa was beginning to develop. This is because this slim body would have helped to avoid body overheating, as well as being good for running long distances on open ground. According to this conception, the fossils attributed to H. erectus so far suggested that this species already had longer legs and shorter arms than its Australopithecus ancestors, which had a fairly efficient bipedal gait, but also had the ability
