Chapter 17: Speciation and Macroevolution

Learning Outcomes

After studying this chapter, you should be able to accomplish the following outcomes.

Separation of the Species

1. Compare and contrast the evolutionary species concept with the biological species concept.
2. List and give examples of five prezygotic isolating mechanisms and three postzygotic isolating mechanisms.

3. Describe and give examples of allopatric speciation including adaptive radiation.
4. Describe and give examples of sympatric speciation including alloploidy.

5. Compare and contrast the gradualistic model of speciation with the punctuated equilibrium model.
6. Use the fossil diversity of the Burgess Shale to support the punctuated equilibrium model.
7. Give examples to show that Hox genes probably play a role in macroevolution.
8. Use the evolution of the horse to show that evolution is not goal oriented.
