Study Questions for Lecture 4 1. How is mutation a force of evolution? Is it weak or strong? Why? 2. What is migration? What are its genetic consequences? What is another name for it? 3. What is genetic drift? In what sized populations does it occur most readily? What are two particular kinds of genetic drift? 4. What are two kinds of non-random mating? In what important ways do they differ? 5. What is inbreeding? What is the consequence of inbreeding on the genetic structure of a population? 6. What is evolutionary fitness? How is measured? What does the process of natural selection do to the average fitness of a population over time? 7. Describe the different modes of natural selection. Know some examples from each and be able to recognize figures that display each kind. 8. What is sexual selection? Why does sexual selection exist (i.e., what are the components of the theory of sexual selection?)? What is intersexual selection? What is intrasexual selection? Know examples of each. 9. Does natural selection shape perfectly adapted organisms? Why or why not? 10. Is all evolution adaptive? Why or why not?
