Document Summary
Partial tibia provides strong evidence for bipedality. Primitive (ape-like) cranial morphology and derived (human-like) post cranial morphology. Ethiopia (hadar, omo, and fejej) and tanzania (laetoli) Complex morphology exhibiting some ape-like traits (eg. sagittal crests- tells us about chewing) and hominin-like trait (eg. valgus knee) Big toes hardly diverged from the rest of foot, unlike in chimps. Gait was heel-strike followed by toe-off ; the way modern humans walk. Sealm (peace): fossilized skull and skeleton remains of a 3 year old girl dated to 3. 2mya. Foot and lower limb remains: bipedal locomotion. Scapula and hand bones: gorilla-like scapula and long and curved manual phalanges indicate importance of arboreal behaviour. Dental features difer from those in a. afarensis. Postcranial features similar to those in a. afarensis. Large face, huge zygomaics (cheek bones), large skull crest and enormous teeth. Remarkably primiive hominin at such a late date. Morphology broadly similar to that seen in a. aethipicus.
