ANTHR 101 Lecture Notes - Lecture 11: Sagittal Crest, Robert Broom, Paranthropus Aethiopicus
Document Summary
Transition between australopithecines and early homo (us) Long arms, tiny hands, smaller teeth (suggest that eating higher quality foods or use of tools) Pelvis similar to ours, larger brain size, low brow ridge, One of the first times we found an almost intact skeleton. Australopithecus africanus evolved into austhralopithecus sediba which then evolved into the genus homo. First found by robert broom, scottish physician. Broad cheekbones, large teeth related to powerful chewing. Robust because they have big cheekbones and powerful chewing. Sagittal crest is a buildup of bone on the top of the skull for muscle attachments. Diet emphasizing rough vegetable foods, possible some meat. Robusticity only refers to the crania and teeth. Postcranial material does not differ greatly in size. Nano micron slivers from the enamel to test. Robust hominids lived in a wide variety of environments and did not go extinct because of one environment. Isolated teeth, look smaller as they wear down because they are v-shaped.
