EVOLUTION & Classification (Standard B-5.1& 5.3: Summarize the process of natural selection and how diversity within a species increases the chances of its survival.) (Standard B-5.4: Explain how genetic variability and environmental factors leads to evolution.) (Standard B-5.5: Provide examples of evidence for evolution.) (Standard B-5.7: Use phylogenetic tree/cladogram to identify relationships among different groups of organisms.) Natural Selection – Four Principles Micro- vs. Macro-evolution Factors Influencing Genetic Variability Leading to Evolution (always acts on PHENOTYPES!) (in addition to natural selection) 1. Overproduction of Offspring: Genetic drift: 2. Variation: Gene flow: 3. Adaptation: Species: Non-random mating: * fitness: Gene pool: Mutations: 4. Descent with modification: Taxonomic Categories Anatomy: S Speciation Evidence of Evolution Binomial Nomenclature: Reproductive/Temporal: Paleontology: K Geographic: Embryology: P C Behavioral: Biogeography: O F Biochemistry: G Patterns of Evolution Gradualism: Punctuated Equilibrium: Adaptive Radiation/Divergent Evolution: Convergent Evolution: Coevolution: Extinction:
