Document Summary

Chapter 6-9: hominins, human variation, & forensic anthropology. Some key australopithecines: the first real hominins y australopithecus anamensis y australopithecus afarensis y australopithecus africanus y australopithecus aethiopicus y australopithecus boisei y australopithecus robustus. Australopithecus anamensis y kanapoi, kenya y 4. 3-3. 9 mya y tooth row is parallel (ape-like) y partial tibia provides strong evidence for bipedality y primitive (ape-like) cranial morphology and a derived (human-like) postcranial morphology. Australopithecus africanus y various sites in south africa y 3. 0-2. 3 mya y average brain is 458 cc. y dental features differ from those in a. afarensis y postcranial features similar to those in a. afarensis. Australopithecus aethiopicus y west turkana, kenya y 2. 7-2. 3 mya y large face, huge zygomatics, large skull crests, and enormous teeth y remarkably primitive hominin at such a late date. Australopithecus boisei y olduvia, taizania y 2. 2-1. 2 mya y hyper-robust hominin y morphology broadly similar to that seen in a. aethiopicus y contemporaneous with members of the genus homo.
