Document Summary
Miller-urey: duplicated conditions of early earth. Organic evolution: change in population from one generation to the next. Lamarck: use vs. disuse (ex: giraffe, if animals didn"t use it, they lost it (became vestigial) Epigenetic inheritance (environment can play a role) Cuvier: paleontologist, came up with the idea of catastrophism, influenced by the fact he was a creationist. Kimura: neutral theory, genetic drift ( associated with change in small sample size, random, pseudogenes. Hutton: gradualism: large changes occurred over time, father of modern geology .
