CH 14 and 15 EXAM REVIEW: EVOLUTION
1. Define and provide examples of fossils? In what kind of rocks do fossils generally form?
2. What is Radio Carbon dating? What is it used for?
3. Define “Half-life?”
4. How does the “Absolute Age” compare to the “Relative Age?”
5. Review the basics of History of life on earth (Ch 14)
6. What did Darwin observe on the Galapagos Islands? What did he notice about the finches?
7. Review Lamarck’s theory of evolution. What was his major concept for the Theory of Evolution? (Hint: remember… if dad has muscles, is
the baby going to have muscles?)
8. Briefly describe the work of Thomas Malthus and his contribution to Darwin’s theory of Evolution.
9. Describe artificial selection.
10. Vestigial structure (definition and examples)
11. What is an adaptation? Can it be behavioral? Explain. Can it be physical? Explain
12. What does the term fitness mean?
13. What is an acquired trait? Provide an example.
14. List the 7 sources of evidence for evolution
15. Define evolution
16. Define Natural Selection
17. Does Natural Selection act directly upon the genotype or phenotype? Provide an example
18. Why is genetic (natural) variation necessary in order for evolution to occur?
19. What are the 4 main causes of genetic variation? (You may need to go back and review your genetics notes if you don’t remember).
20. Define population.
21. Define Gene Pool (what is included in a gene pool?)
22. Define Genetic drift. What type of populations does this tend to act upon (large or small)?
23. What affect does genetic drift have on the gene pool (increase or decrease variation)?
24. Mutation (including the various types)
25. Define the following and provide an example for each: Disruptive selection, stabilizing selection, directional selection
26. What 5 factors/events can disrupt genetic equilibrium?
27. What are the various ways in which populations can become isolated?
28. Speciation (definition and provide an example)
29. How can analyzing DNA help scientists determine the amount of time that has passes since species shared a common ancestor (what is the
trend)?
30. Explain why genetic variation is important for the survival of a population?
