Primates_ (pred. wiping// habitat expnsion: arboreal hypth_ filling the terminal branch niche, visual predation_ terminal branch niche + hunting adaptations, angiosperm radiation_ terminal branch niche + exploiting fruits & flowers. Model 1= primitive catarrhine slctn for lrgr body slctn to maintain access to arboreal rsourcs = proconsul & morotopith (& lngr lives) (land) (trees) Model 2= primitive catarrhine slctn for enhanced ability to exploit arboreal rsourcs slctn for lrgr body= morotopith. Miocene"s african gap- (begun)= apes from europe (following food patches) (pilbeam)= apes always in africa (haven"t found yet) Bipedality: darwin= hunting stone tools hand specialization bipedality. 6. thermo-regulation= upright posture= : energy-efficiency= upright walking for long distance travel {(-_-) tested on mdrn species, lovejoy= provisioning & monogamy= babies required resources free hands. Walk between patches obligate bipedality solar radiation exposure (demographic dilemma) Hutton & lyell (geologists)= uniformitarianism (constant geo patterns of ) & deep time. 1800s lamarck (scholar)= 1st idea of mechanism of (inheritance of acquired traits)
