This highlights the importance of taking this bias into account each time these data sets are used. A study led by Spanish researchers has revealed that Homo erectus , the first human ancestor to spread throughout the Old World, from Africa to Southeast Asia, and which until now was considered slender and slender, was actually compact, squat and strong. This is revealed by a work by paleoanthropologists from the Higher Council for Scientific Research (CSIC) and the National Center for Research on Human Evolution (CENIEH), who have reconstructed in 3D the shape of the rib cage of the Homo erectus specimen known as the child of Turkana, a 1.5 million-year-old juvenile skeleton found in Kenya in 1984. The study, co-led by Markus

Bastir, from the National Museum of Natural Sciences MNCN-CSIC, and Daniel García Martínez, from CENIEH, is published in the journal Nature Ecology and Evolution . The work of the CSIC and the CENIEH reconstructs in 3D the Namibia Phone Number List thorax of the Turkana child, the most complete H. erectus skeleton , dated at 1.5 million years “Surprisingly, the Turkana boy had a deeper, wider and shorter thorax than that of modern humans,” says researcher Markus Bastir. “This suggests that H. erectus had a more robust body construction than was supposed, since until now the body shape of this species was seen as slender or stylized, which was associated with its ability to travel long distances”, Add. “Therefore, it appears that the slender shape of the modern human

body, with a narrow thorax and pelvis, evolved more recently than previously thought. Instead of appearing as early as the appearance of H. erectus , some two million years ago, it would have appeared with our species, H. sapiens ”, explains García Martínez. A large lung capacity Studies of how this individual H. erectus walked and ran have largely been limited to the legs and pelvis. However, for endurance racing, his respiratory capabilities would have been relevant as well. “Until now, this aspect had not been investigated in detail, as evaluating chest movement and respiratory capacity based on fossils of fragmented ribs and vertebrae is difficult with conventional methods,” explains Bastir. “Now, thanks to the introduction of increasingly sophisticated
