Document Summary
14 billion years ago the universe was created. 4. 5 billion years ago the earth was created. 66 million years ago dinosaurs went extinct. 10,000 years ago species make settlements, start farming. How we know what lived here before. Early naturalist who classified life"s diversity by creating a circular system. Aristotle: life comes from mud, somethings get stuck. Used old testament to determine the age of earth. Written authority, not evidence of senses, observations. Fixity of species: special creation of individual species. Higher on the chart meant more noble to creature. Steno, anatomist and geologist (and bishop), doesn"t trust christian"s views on fossils. Argues fossil record was chronology of living creatures. The earth was subject to slow but continuous cycles of erosion and uplift. Fundamental force was subterranean heat that creates chemical reaction that would cause earth"s crust to heat and expand thereby causing rock strata to uplift, deform, tilt. Geological changes could be accounted for by slow natural processes.
