Document Summary
Uniformitarianism-concept that earth"s present landscape was produced by past action of the same gradual geological processes that we observe today. Questions: be able to explain how the theory of evolution developed from the early 1700s. Buffon (species created, then evolve) changed over time through natural processes. Hutton (gradual geologic change) lyell builds off of his idea. Lamarck (mechanism of species change) organisms evolved through the inheritance of acquired traits. Cuvier (catastrophism)species were initially created, then a catastrophe(noah great flood) produced layers of rock and destroyed many species, fossilizing some of their remains in the process. Smith (sequence of fossils) older fossils are on the bottom, younger ones are on the top. Lyell (earth is very old) introduced the idea of uniformitarianism. Lamarck"s insight that inheritance plays an important role in evolution had an important influence on later biologists who discovered the key mechanism of evolution. (mendel-pea plant inheritance)
