Chapter 17: Speciation and Macroevolution

Learning Outcomes

17.1 How New Species Evolve

1. Compare and contrast the processes of microevolution and macroevolution.
2. Identify and compare features of pre-zygotic and post-zygotic reproductive isolation.
3. Explain three ways that species are defined.

17.2 Modes of Speciation

1. Define two modes of speciation and give examples of each.
2. Identify an example of adaptive radiation.
3. Distinguish between coevolution and convergent evolution.

17.3 Principles of Macroevolution

1. Discriminate between the gradualistic and punctuated equilibrium models of evolution.
2. Explain how gene expression can influence speciation.
3. Support, by providing an example, the argument that macroevolution is not goal oriented.
