The jaw comes from an adolescent male of about 12 years of age. Claimed as one of the most significant discoveries in the field of human evolution, the fossils possibly represent the oldest known human ancestor after the split of the human line from that of the chimpanzees. Human evolution is the biological and cultural development and change of our hominin ancestors to modern humans. The evolutionary and biomechanical . Humans are characterized by a parabolic arcade with short postcanine tooth rows and small canines, whereas apes have long, U-shaped arcades with large canines.
