Objectives:

1. Explain how Darwin’s voyage on the Beagle influenced his thinking. (Ch. 13)
2. Explain why the concept of evolution is regarded as a theory with great significance. (Ch. 13)
3. Explain how fossils form and why the fossil record is incomplete. (Ch. 13)
4. Explain how homologies, the fossil record, and molecular biology support evolution. (Ch. 13)
5. Describe Darwin’s observations and inferences in developing the concept of natural selection. (Ch. 13)
6. Explain how the work of Thomas Malthus and the process of artificial selection influenced Darwin’s development of the idea of natural selection. (Ch. 13)
7. Explain why individuals cannot evolve and why evolution does not lead to perfectly adapted organisms. (Ch. 13)
8. Describe two examples of natural selection known to occur in nature (Ch. 13)
9. Explain how mutation and sexual reproduction produce genetic variation. (Ch. 13)
10. Explain why prokaryotes can evolve more quickly than eukaryotes. (Ch. 13)
11. Define genetic drift and gene flow. Explain how the bottleneck effect and the founder effect influence microevolution. (Ch. 13)
12. Explain why natural selection cannot produce perfection. (Ch. 13)
13. Distinguish between microevolution and speciation. (Ch. 14)
14. Compare the definitions, advantages, and disadvantages of the different species concepts. (Ch. 14)
15. Describe five types of prezygotic barriers and three types of postzygotic barriers that prevent populations of closely related species from interbreeding. (Ch. 14)
16. Explain how reproductive barriers might evolve in isolated populations of organisms. (Ch. 14)
17. Compare the gradual model and the punctuated equilibrium model of evolution. (Ch. 14)
18. Distinguish between homologous and analogous structures and provide examples of each. Describe the process of convergent evolution. (Ch. 15)
