What is natural selection? 2-Explain the History of Life in Terms of Biodiversity, Ancestry, and the Rates of Evolution 1. What is adaptive radiation? Give an example. 2. What is convergent evolution? Give an example. 3. Why was myosin so interesting to evolutionary biologist? What did it show? 4. What is Biodiversity? 5. How do biologist used DNA to show how long ago genes branched off from a common ancestor? 6. What is speciation? 7. What are two rates of Speciation? Explain each. 8. What can cause speciation? 2-Explain the History of Life in Terms of Biodiversity, Ancestry, and the Rates of Evolution 9. What is adaptive radiation? Give an example. 10.

Evolution Reading Questions Name_____________________________________ 4- Relate Natural Selection to Changes in Organisms 1. What is a key to Darwin’s theory of organisms struggling for existence? 2. What causes gene pools to change over time? 3. Fill in the following chart. Type of Selection Stabilizing Description of what happens Directional Diversifying Disruptive Balancing 4. Does the strongest, biggest, and most aggressive animal always have the highest fitness rating? Explain your answer. 5. Does natural selection produce NEW genotypes? Explain. 5-Recognize the Role of Evolution in Biological Resistance 1. How has the use of pesticides and antibiotics caused evolution in some species? Explain and give examples.
