Document Summary

Some key australopithecines: the first real hominids: a. anamensis. Partial tibia (shin bone) provides strong evidence for bipedality, main weight bearing bone in lower limb, seemed to have ability for extended upright bipedal locomotion. Still aboreal, waist up like apes waist down like humans (recent discovery) Primitive (ape like) cranial morphology and a derived (human like) post cranial morphology: a. afarensis. Ethiopia (hadar, omo and fejej) and tanzania (laetoli) Complex morphology exhibiting some ape-like traits (sagittal crests and hominid like traits), canines: vampire teeth, still retains ape like condition of having large canines. Single, sexually dimorphic species or two species. Lived in africa for over a million years, long time line. Post cranial (principally pelvis and knees) look like bipedal hominid, small creatures. Very large males and small females (still not sure whether that"s the case or whether its two entirely different species) Footprints dated back to 3. 6 mya in laetoli, tanzania (two sets of footprints over volcanic ash)
