Unit 7 Test Review
Natural Selection
Test: Monday January 25th
Please answer these questions in your notebook during class and bring for the test on
Monday.
1. Define the term phenotype.
2. What is the difference between a theory and fact?
3. Who was Charles Darwin?
4. Where did Charles Darwin study to develop his theory of evolution?
5. What is natural selection?
6. What is adaptation?
7. What is a behavioral adaptation and an example?
8. What is an anatomical adaptation and an example?
9. What is a physiological adaptation and an example?
10. What is artificial selection? Give an example.
11. What is sexual selection? Give an example.
12. What is the difference between artificial, sexual, and natural selection?
13. What is survival of the fittest in natural selection terms?
14. Does natural selection occur on an individual or population level?
15. What is selective pressure?
16. What does a graph look like of a population who is under no selective pressure?
Be sure to label the axes.
17. What does a graph look like of a population under stabilizing selection? Describe
a scenario where you would observe this type of selection.
18. What does a graph look like of a population under disruptive selection? Describe
a scenario where you would observe this type of selection.
19. What does a graph look like of a population under directional selection? Describe
a scenario where you would observe this type of selection.
20. What are the four evidences of evolution?
21. How does DNA evidence support the theory of evolution?
22. How do fossils support the theory that organisms evolve over time? Use
examples.
23. How do homologues/analogous structures provide evidence supporting the theory
of evolution?
24. What is a vestigial structure? Give an example.
25. How can we use amino acid sequences to support evolution? (think back to the
amino acid worksheet)
26. How does embryology support the theory that organisms are derived from a
common ancestor?
