Document Summary
Biology 360: evolution 2 the fossil record midterm review. Geological time scale: divided into a hierarchy of units: eras, periods, and epochs. The activity of organisms can be fossilized as well e. g. worm burrows. To discover different worlds of organisms: worlds of only microbes where there was 10x more 02, lizard world. To track changes in climate and biodiversity, predict future events by understanding the past. Evolution: all species are related to each other, i. e. tree of life. Age dating: use of fossils to date rock; industrial geology. In the early 1800s, only a few fossils were known. Progressionism and evolution: simplest life forms in oldest rocks progressed to more complex ones in older rocks. Darwinian evolution: darwin developed evolution by natural selection: considerable variation in life forms, and no fixed type of alleles/genes. Surviving individuals adapted to do so, and these adaptations would be inherited. The 1800s were a great time of exploration and discovery.
