ANTH 101 Chapter Notes - Chapter 2: Darwinism, Phenotypic Trait, Distant Relatives
Document Summary
Pre-darwinian views of the natural world: essentialism, the great chain of being, catastrophism and uniformitarianism evolution. What is natural selection: population thinking. How did biologists learn about genes: mendel"s experiments, the emergence of genetics. What are the basics of contemporary genetics: genes and traits, mutation, dna and the genome. Genotype, phenotype and the norm of reaction. Species can change over time and give rise to new species: meaning that all species share some common ancestry. Evolution is has been the only theory that hasn"t totally faltered under the close scrutiny of the scientific community it still can explain the diversity and similarities that we see day to day. Two material types: evidence of change over time, evidence of change across space. Living organisms compared to their fossilized distant relatives were very different material evidence of change over time. Greeks thought world had been and would be around forever. Judeo-christian era thought that the world was young and would end soon.
