Document Summary
Anth 1120 lecture outline dr. e. finnis. Recent teeth for dna, usually for seeing what they were eating. We are well adpated for this able to run away at length, hunt, competition , scavenging. Sexual dimorphism: loss of c/pe honing mechanism, enamel thicknesses (increase)- possibly eating harder" things softer enamel. Paranthropus-robust early hominins with very large teeth large jaws and a saggital crest-bone mohawk" on top of skull (indicator of paranthropus speciecs) (muscle attachment for stronger jaws)-coarse vegetation. General shift towards larger brain sizes and increasing brain complexity. Endocasts impressions on inner surface of the cranium and outer surface of the brain in fossil record can make molds. Brain organization-don"t worry too much about this. Two hemispheres, 4 lobes (frontal, parietal, occiptal, temporal) Implication of brain complexity energy redirection need better quality food. Morphology: the form (size, shape) of anatomical structures.
