Document Summary
General trends of early homo in comparison to australopithecines. Thin walled no crests: rounded vault, weakly projecting ridges. Dentition: anterior teeth generally the same size as australopithecus, premolars and molars are reduced compared to australopithecines (but larger than modern humans) 752 cc: rounded cranial vault, no heavy crests, robust face. Back teeth still quite large (but < australopithecines) Manuports: unaltered objects carried some distance before use. Important in brain evolution: emphasizes manual dexterity, requires a complex, abstract thought process. Sites: lake turkana: olduvai gorge, hadar, omo. All purpose chopping tool: made from smooth water worn cobbles, multi-purpose. Anvil direct percussion: rock used to strike flakes off cobble. Flake: chip of rock off the cobble. Large rock that you strike the cobble against or place the cobble on. Cultural significance of oldowan tool tradition: new additions to diet: meat group sharing scavenging. Probably resulted from an adaptation to a new environment.
