Evolutionary Tree Practice!
DUE next class period.
Directions: Read the essay “Organizing Diversity” on p191-195 and then answer the following questions in your
notebook on p.25.

8. Name all the organisms in the Order Perissodactyla.
9. Name all the organisms in the Family Equidae.
10. Write in the correct format the Genus and species name for the Grevy’s zebra?
11. Describe the evidence on which the evolutionary relationships in the tree are based on?
12. Explain why scientists will never be able to completely prove evolutionary relationships.
13. Add the words biological classification and binomial nomenclature to your personal glossary at the back of your
notebook.
