BIO 102 Objectives Unit 3 Chapter 22 Descent With Modification 1. Compare the idea of the fixity of species with modern evolutionary thought 2. Describe the binomial nomenclature system devised by Carolus Linnaeus and provide examples 3. Discuss the work of Charles Lyell in geology that incorporates uniformitarianism 4. Explain how two of Lamarck’s explanations for the mechanism of evolution -- use and disuse, and acquired characteristics were not validated. Use the example of the giraffe neck. 5. Discuss the findings Charles Darwin presented in On the Origin of Species including the concepts of random variation, number of offspring produced vs resources, survival of the fittest, reproductive fitness, and descent with modification 6. List some of the species in the Galapagos islands that Darwin observed while on the Beagle 7. Explain how traits selected upon by nature may be preserved in a population as adaptations 8. Associate the idea of a common ancestor between related species suggests a unity of life that developed over millions of years 9. Observe that evolutionary trees unite species using evolutionarily shared characteristics 10. Explain why individuals do not evolve genetically while populations do 11. Define the term “fossil” and explain how fossils form 12. Examine skeletal evidence that whales evolved from a land mammal 13. Examine mammalian forelimb in humans, cats, whales, and bats and explain why these structures are considered to be homologous 14. Observe that embryology supports the finding that vertebrate animals share a common developmental plan 15. Provide examples of vestigial structures in snakes and how vestigial structures can provide information on ancestry 16. Examine genetic homology in protein sequence and how amino acid sequence differences support anatomical data as evidence evolutionary relatedness among species 17. Provide examples of convergent evolution in Australian and North American mammals 18. Explain how geographical changes can affect species radiation and extinction patterns. Use the example of changes since Pangaea. 19. Discuss the role of sexual selection in the peacock (video) 20. Analyze the experiment in guppy predation that provides direct evidence of genetic change over time in a population. 21. Contrast between a hypothesis and a theory in science BIO 102 Objectives Unit 3 Chapter 23 The Evolution of Populations 1. Contrast phenotypic and genotypic variation 2. Explain how the frequency of heterozygosity in a species or population relates to genetic diversity 3. Discuss the cheetah population as an example of the potential effects of low genetic diversity 4. Read about the mice populations on the Madeira Islands and their evolution as isolated groups 5. Examine a geographical cline 6. View a point mutation in DNA and its potential neutral, harmful, or beneficial effects on fitness 7. Review and summarize a paper on gene duplication 8. Examine the mutation rate in plants and animals 9. Review the generation of genetic diversity via mutation, independent assortment, and sexual reproduction 10. List the assumptions made in Hardy Weinberg model of a population that is not evolving 11. Examine the effect natural selection and genetic drift of allele frequencies 12. Describe adaptive evolution with respect to changes in allele frequencies in a population 13. Analyze the effect of DDT on the adaptive evolution of Drosophila in the United States 14. Contrast between the founder effect and bottleneck mechanisms of genetic drift 15. Examine how harmful allele frequency, general changes in allele frequencies, and a decrease in genetic diversity can arise via genetic drift 16. Explain why natural selection is a blend of chance and selection 17. Describe the effect of drought on the ground finch population genetics in the Galapagos island of Daphne Major. Interpret a graph correlating beak size with survival. 18. Compare directional, disruptive, and balancing forms of natural selection, providing an example of each. 19. View a video of sexual selection the peacock 20. Examine sexual dimorphism 21. Compare intrasexual and intrasexual forms of sexual selection 22. Explain why diploidy maintains genetic diversity in a population by maintaining recessive alleles 23. Analyze the heterozygote advantage in malarial infection outcomes in humans 24. Provide evidence for why natural selection cannot fashion perfect organisms
