ANTH 1001 : Final
Document Summary
Early fossil record: 5 genuses, sahelanthropus thcadensis 7-6 mya. Ardithecus kadabba 5. 8-5. 2 mya: ardipthecus ramidus 4. 4 mya. Lumpers and splitters: lumpers emphasize similarities more than differences. They lump them into smaller categories, so they recognize fewer species: splitters emphasize more species. Immediate behind the eye orbit is the constricted or narrow of the cranial vault: supra-orbital torus (sot) brow-ridge . Thickened area of bone above the eye orbits: prognathism/orthognathism. Prognathism: the anterior projection of the maxilla, more ape-like characteristic. Orthognathism: flattened and relatively straight maxilla, more humanistic characteristic, sagittal crest. A crest of bone at the sagittal sucher, which runs down the center of your head from front to back: nuchal crest. A sharp ridge of bone in the back of the skull. Antler and wood tools were used as well as stone. Not many bone tools: schoningen, germany- site for earliest evidence for non stone tools.
