Document Summary

Macroevolution- over long periods of time environmental isolation creating genetic changes that lead to new species: hominin evolution. Microevoltuion-genetic changes over shorter periods of time with no environmental isolation or speciation: human variation. Explaining how hominin evolution happen: describing speciation. Using observed shared adaptations: assign fossils to a taxon(like species) by homologies. We give fossils dates of living in two ways: relative dating: stratigrahy: how earth sediments are deposited over time, absolute dating: Molecular mtdna dating: counting mutations (doesn"t date fossils but. Dna mostly living dna) radiometric techniques: measuring loss of unstable radioactive isotopes. Human taxonomy: primates, anthropoids, catarrhines, hominoids, hominids, hominins, humans, recent humans, amhs. Meteor: mass extinction, end of mesozoic era, cenozoic era begins: tropical climates develop. Primate traits evolve: smell to sight, grasping, nose to hand, brain/body size ratio, parental investment, socialbility. Terrestrial monkeys: whether you"re monkeys or apes (live on ground or not) The paleocene (65-54 million years ago: primates appear.
