Contrast artificial selection and natural selection. 12. Biochemistry provides data that can help in the identification of possible 13. (2.1) Describe the difference between homologous and analogous structure. Make sure to include how each provides evidence for evolution. 14. The similarities in embryonic development suggests that 15. What is the best way to prove that current day whale and horse species are more closely related to each other than previously thought to be? What 2 evidences could you use to show they are more closely 2
related to each other than a whale to a fish? Explain how these evidences demonstrate the degree of relatedness. Outcome 3 Components of Natural Selection 16. The Galápagos finch species are an excellent example of speciation. Explain what this means. 17. Describe: a. adaptation. b. reproductive isolation. c. Geographic isolation d. Temporal isolation 18. What is the movement of genes into and out of a gene pool called? 19. Natural selection can best be defined as the. 20. Explain how reproductive isolation is important to the process of speciation. 21. Explain why natural selection acts on the phenotype of an organism instead of its genotype? 22. Which of the following is NOT a component of natural selection? 3
a. Competition for food and space b. Variation among species c. Survival and reproduction d. Producing few offspring 23. What are the characteristics in a population that would provide the greatest potential for evolutionary change? Outcome 4 Relatedness Among Species 24. Who was Linnaeus? What did he create? 25. Write your first and last name using the rules for writing a genus and species. 26. What are the three Domains of life? 27. Cladograms show 28. In the above diagram to the right, B, C, and D represent organisms that exist in the present time and show a striking similarity to each other when their bone structures are compared. In the diagram, letter A most likely represents: 29. Which levels of the taxonomical classification system contains the most variety of organisms? 4
