Document Summary
tooth row parallel (ape-like), partial tibia provides evidence for bipedality. primitive/ape-like cranial morphology; derived (human-like) post cranial. ethiopia (hadar, omo and fejej) and tanzania (laetoli) 4. 2-3. 0 mya a very successful species. complex morphology, some ape-like traits (ex. sagittal crests) and hominin-like traits (ex. valgus knee) demonstrate that early hominins were bipedal; big toes hardly diverged from the rest of foot, unlike in chimpanzees. gait was heel-strike followed by toe-off ; way modern human walks. various sites in south africa; 3. 0-2. 3 mya. average brain size is 458cc, indicative of bipedalism. dental features differ from a. afarensis, but postcranial features similar. large face, huge zygomatics, large skull crests and enormous teeth. remarkably primitive hominin at such a late date; more ape-like. hyper-robust hominin; contemporaneous with members of genus homo. morphology broadly similar to that seen in a. aethiopicus. swartkrans and kromdraei, south africa; 2-1 mya.
