ANT101H5 Lecture Notes - Lecture 10: Australopithecus
Document Summary
Species in the videos may be in the quiz. Know hominins by form and by geography: difference between sagittal and nucal crest, difference characteristics. All hominins are habitual bipeds (stood upright) What differentiates hominins from all apes is habitual bipedalism. Robust: has all crests, sagittal, nucal, wide mid-face, huge molars: had a specialization of plant species, because of eating habits they are not direct link to humans. Hominins autralopithecus: first: afarensis, humans came off from the gracile rather than the robust australopithecus, africanus may have derived from afarensis. Final exam: know contenders of hominoids to hominins, from apes to australopithecus, not the same as contenders of hominins to homo. Increase in brain size: reduction in dentition, standardized tools, 1st condenter: leakey, platyos: reduced dentition, 2nd contender: garhi, 3rd contender: chad, reduced dentition, 4th contender: sediba, seems to be the link b/w africanus & homo.
