1)
2)
4)
5)
3)
6)
2. List 5 ways fossils provide evidence of evolution
3. Define evolution (page 450)
4. What observations did Charles Darwin make as a naturalist aboard the Beagle?
5) Use figure 16-2 (page 452) to explain how tortoises on Isabela Island and Hood Island evolved from certain
characteristics because of the environmental influence. RSQ and be thorough.
6) Describe how artificial selection works and provide one plant and one animal example. RSQ (page 458)
7) How does artificial selection support the theory of evolution?
8) Use notes to define natural selection (page 463) and summarize the requirements necessary for natural selection to
occur (460-461). (Note the book does not explicitly say the trait must be inherited, but this is necessary). RSQ
9. Define fitness (page 461).
10. List five adaptations that may help an individual species survive – include both plants, animals and bacteria.
11. Define biogeography (page 465)
12. How does the geographic distribution or biogeography of species today relate to their evolutionary history? (Page
465).
13. How old is the Earth and what technology helps date the Earth? (Page 466).
14. What is radiometric dating and how does it support the theory of evolution? List 3 ways from notes.
15. An original rock had 60 atoms of Uranium 238.
A) After one half-life of 4.5 billion years, how old is the sample?
b )How many atoms are remaining?
C) After two half-lives, how many atoms remain? How old is the sample?
16. A sample has 5 atoms of radioactive uranium 235 and 65 lead present. a. What percent of the radioactive isotopes
remain?
b. Use the graph to determine the percent remaining to find the number of half-lives.
c. If the half-life of uranium 235 is 704,000,000 million years, how old is the sample?
17. The radioactive isotope dates a fossil of a once living organism. Carbon-14 has a half-life of 5730 years. There is 20
atoms of the parent isotope and 5 of the daughter isotope. What is the age of the fossil?
18. Describe how Taaklalik provides evidence of evolution. Use the term transitional species within the definition.
19. Define homologous structure and describe how homologous structures support the theory of evolution? (page 468)
20. Do homologous structures suggest a common ancestor or common environmental pressures?
What about analogous structures?
21. Define analogous structures and describe how analogous structures support the theory of evolution. (page 469)
22. Write an H if the scenario suggests evolution by homologous structure or an A if it represent evolution of analogous
structures. Frog limb and chicken limb
Butterfly wing and bird wing
Leg of a dog and flipper of a whale
jointed legs of insects and humans
fins of fish and flippers of whales
23. Define vestigial structure and describe how vestigial structures add support to the theory of evolution.
24. List two examples of vestigial structures.
25. Note: Patterns in embryological development support the theory of evolution.
26. How do molecular structures support the theory of evolution (provide examples) (use the book and notes)
27. What is the Hoxc8 Gene and how does this support the theory of evolution?
28. How does the research by Peter and Rosemary Grant show natural selection? (Page 472- be specific)
