Precisely when upright strolling emerged within the evolutionary historical past of people stays hotly debated. Fossil analyses recommend that a number of hominid species ambled round on two legs about 5 million to 7 million years in the past. An higher leg bone of the oldest identified, 7-million-year-old Sahelanthropus tchadensis, bears indicators of upright strolling together with an inside projection close to the hip joint, scientists reported in 2022 (SN: 9/24/22). However no longer all paleoanthropologists are satisfied the ones options turn out a two-legged gait. And a few scientists assume the bone belonged to an ape that can have walked upright now and then.
