Researchers in Bulgaria discovered a 7.2-million-year-old thighbone showing signs of bipedal walking, potentially predating African hominin fossils and suggesting upright walking may have evolved in Europe rather than Africa. The femur, attributed to the ape species Graecopithecus freybergi, displays anatomical features supporting bipedality, though some scientists remain unconvinced without additional fossil evidence.
