Chapter 16 : Darwin’s Theory of Evolution (Miller & Levine p 448)
1. What was Charles Darwin’s contribution to science?
What three things did Darwin notice about species diversity?
2. How did Lamarck explain how species evolved?
What is an acquired characteristic?
Lamarck thought that acquired characteristics could be passed on the next generation.
Was he correct? Explain
3. How is inherited variation used in artificial selection? Give an example.
4. Define the conditions for natural selection:
a. struggle for existence
b. variation and adaptation
c. survival of the fittest
5. How does natural selection differ from artificial selection?
6. How does natural selection lead to populations that gradually change over time?
7. How do fossils support evolution?
8. Explain the difference between homologous and analogous structures.
Which are more important to evolutionary biologists? Why?
9. What are vestigial structures? Give an example.
10. What evidence of evolution comes from our understanding of molecules?
Chapter 17: Evolution of Populations (Miller & Levine p 480)
11. How is evolution defined in genetic terms? (allele is a form of a gene; frequency is the same
as percent)
12. List two sources of genetic variation.
What is genetic drift?
13. What 5 conditions are needed to maintain gene equilibrium in a population?
14. What is speciation?
How would geographic isolation lead to a new species?
15. What is a molecular clock?
Chapter 19: History of Life (Miller & Levine p 536)
16. What is relative dating of fossils?
17. How old is the earth?
18. Explain how punctuated equilibrium is different from gradualism.
19. What is adaptive radiation (sometimes called divergent evolution)? Give an example.
20. What is convergent evolution? Give an example.
21. What is coevolution? Give an example.
22. What do scientists think were the main gases in the atmosphere of early earth?
23. What did Urey and Miller’s experiment show?
24. How did photosynthetic bacteria change the atmosphere?
