1. Diversity of Life Reading Reflection #6
By: E.O. Wilson
Chapter 7: Adaptive Radiation

2. Review: Habitat vs Niche

3. Adaptive Radiation – Darwin’s Finches

4. Adaptive Radiation - Honeycreepers

5. Adaptive Radiation - Cichlids

6. Divergent Evolution
All three previous slides are examples of divergent evolution
Natural selection due to various selection pressures
Speciation occurred

7. Convergent Evolution

8. Reading Reflection
What is adaptive radiation? What is convergent evolution? Give an example of each
Explain some of the adaptations that allowed the honeycreepers of Hawaii and the finches of the Galapagos to extend into available niches.
Use the example of the mammals of the Americas and Australia to explain convergent evolution.
Would you rather be “successful” or “dominant” in biology as defined by Wilson? What set of organisms do you think embody this from the reading?
