As you may know, in contrast to the arched foot of humans, in chimpanzees and gorillas the sole is flat.īennett MR, Harris JWK, Richmond BG, Braun DR, Mbua E, Kiura P, Olago D, Kibunjia M, Omuombo C, Behrensmeyer AK, Huddart D, Gonzalez S (2009) Early hominin foot morphology based on 1.5-million-year-old footprints from Ileret Kenya. This suggests that by about 1.5 million years ago, our ancestors were already walking very much as we do today. The Ileret footprints indicate that the foot morphology had already evolved away from that of the common primate ancestor, with a larger range of movement and an opposable big toe, towards a form better suited to more efficient pushing off when walking along the ground, with the big toe parallel to the other toes and the foot arched. The scientists found that the footprints at Ileret matched what would be expected from height and weight estimates for Homo ergaster/erectus, and were different in shape to footprints made by Australopithecus at Laetoli, Tanzania. ![]() The team found the oldest example of foot morphology broadly resembling our own. Fossilized footprints can tell us not only about the shape of hominid feet, but also about the way in which they walked. 2009) used a special apparatus, using the reflection of laser beams, to precisely measure the depth of the footprint.
