Comparison of hominin pelvic bones. Artwork comparing the anatomy of the female pelvic bones of three hominin species; Australopithecus afarensis (left),Homo erectus (centre) and Homo sapiens (right). The A. afarensis baby had a small head circumference at birth and therefore the female had a narrow pelvis. It was thought that H. erectus babies also had a head circumference smaller than H. sapiens at birth. However,fossil evidence from Ethiopia has shown the head circumference to be larger than thought. This suggests that H. erectus was more developed at birth | |
