Groundbreaking Discovery: Fossils Reveal Human Ancestor Walked 3 Million Years Ago — Science News, February 16, 1974
Debates on the emergence of upright walking in human evolution have been ongoing. Fossil analyses indicate that several hominid species walked on two legs approximately 5 to 7 million years ago. A recent study reported that the upper leg bone of the 7-million-year-old Sahelanthropus tchadensis shows signs of upright walking, challenging previous beliefs. However, not all paleoanthropologists are convinced by these findings, and some suggest that the bone may have belonged to an ape that occasionally walked upright.
