The fossils of Sahelanthropus chadensis have been the subject of a long-standing debate over whether it was the first species to walk on two legs rather than four. A team from Chad and France is expected to return to the African site where the fossils were found this year to search for additional finds.
Pre-human instead of prehistoric monkey: The first real pre-human could have emerged earlier than thought. Because already seven million years ago the hominid Sahelanthropus had essential characteristics of a pre-human and at least temporarily went upright, as new analyses of Sahelanthropus fossils now suggest. He could therefore have been our oldest direct ancestor, as researchers report in Science Advances. The upright course was a decisive mi…
Walking on two legs began earlier than we thought
Scientists may have just pushed back the timeline for when our ancestors first started walking upright. A new study suggests that Sahelanthropus tchadensis, a species that lived about seven million years ago, was able to walk on two legs—making it one of the earliest known relatives of humans to show this crucial trait. For years, […] The post Walking on two legs began earlier than we thought appeared first on Knowridge Science Report.
