Ch. 13 & 14 Evolution

1. Understand Darwin's theory on natural selection. What was the name of Darwin's publication on natural selection? Who was Lamark and how did his theory differ from Darwin's.

2. Know the definition of evolution and know the difference between microevolution and macroevolution. What effect does evolution have on populations?

3. How does natural selection produce evolution in populations? What determines if a trait is passed on to successive generations?

4. How does mutation produce variation for evolution?

5. What is a gene pool and allelic frequencies in a population?

6. Relate directional selection to extreme phenotypes in a population.

7. Differentiate between natural selection and artificial selection.

8. What is genetic drift? What influence does genetic drift have on allele frequencies?

9. Know the biological species concept developed by Ernst Mayr. When does speciation occur? What mechanisms specifically, contribute to genetic divergence in a population that may lead to speciation?

10. What is allopatric speciation? How does allopatric speciation promote genetic changes necessary for a species to originate?

11. What is adaptive radiation? Explain how adaptive radiation results in the formation of new species.

12. What types of isolation may lead to speciation?

13. Explain how the fossil record has provided evidence for evolution.

14. How does comparative anatomy demonstrate evolution? How does comparative development demonstrate evolution? How does comparative molecular biology demonstrate evolution? What is a vestigial organ?

15. What is the plate tectonic theory?
