BSC 2011 Study Guide
Chapter 24
Chapter 24 – The Origin of Species
1. How do we define a species through the biological species concept?
2. types of reproductive isolation and examples?
3. What are the limitations of the “BSC”?
4. What other species concepts are there?
5. speciation…allopatric vs. sympatric? examples?
6. sympatric speciation by polyploidy, by sexual selection, by habitat differentiation
7. What is a hybrid?
8. patterns within hybrid zones…reinforcement vs. fusion vs. stability
9. rates and patterns of speciation? gradualism vs. punctuated equilibrium
