Biology Chapter 14. Evolution: A History and a Process Key Terms: Evolution Adaptation Descent with modification Natural selection Fossil Fossil record Extinct Homologous structure Vestigial structure Population Variation Artificial selection Gene pool Microevolution Hardy-Weinberg equilibrium Genetic drift Gene flow Fitness Antibiotic Concept 1 Objectives: SWBAT… Summarize ideas from Darwin’s time that influenced his work. Identify some key observations from Darwin’s voyage that led to his theory. Describe the 2 main points of Darwin’s theory. Concept 2 Objectives: SWBAT… Describe information the fossil record contains about life on earth. Tell how the geographic distribution of organisms relates to evolution. Explain how similarities in structure and development among different species are evidence for evolution. Describe molecular evidence for evolution. Concept 3 Objectives: SWBAT… Summarize Darwin’s theory of natural selection. Compare and contrast artificial selection with natural selection. Relate pesticide resistance in insects to natural selection. Concept 4 Objectives: SWBAT… Explain the significance of gene pools in understanding evolution. Tell how genetic drift, gene flow, mutation, and natural selection contribute to changes in a gene pool. Explain what is meant by the term fitness. Describe recent evidence for microevolution on the Galápagos Islands. Concept 5 Objectives: SWBAT… Explain how natural selection causes the sickle cell allele to persist in some gene pools. Explain how antibiotic resistance may evolve in bacteria.
