2. Organismal form indicates evolutionary relationships. A.Always B.Often C.Sometimes D.Never

3. Learning Goal: To infer evolutionary relationships by comparing molecular structures and functions among organisms. Identify evolutionary relationships Describe limitations Discover new ways Construct evolutionary model Learning Objectives:

6. Fun with organisms 1.take a moment by yourself to consider how these organisms are evolutionarily related. 2.work in groups of two or three and arrange the images you were given. Organize them according to which ones you think are most closely evolutionarily related. 3.write down all the criteria you used to group these organisms.

8. Which animal are alligators most closely related to? A. B. C. Lizard Bird Bat

9. Which animal are hippos most closely related to? A. B. C. Whale Alligator Rhino

10. Which organism are moths most closely related to? A. B. C. Bacteria Plant Fungus

11. Which organism are flowers most closely related to? A. B. C. Volvox Carnivorous plant Fungus

13. Alligators are most closely related A. B. C.

14. Hippos are most closely related to A. B. C.

15. Moths are most closely related A. B. C.

16. Flowers are most closely related to A. B. C.

17. Which other criteria, that we did not consider before, may researchers have used to arrive at the evolutionary relationships we just observed?

19. Alligators are most closely related to A. B. C. Proteins

20. Hippos are most closely related to A. B. C. DNA

21. Moths are most closely related to A. B. C. Carbohydrate

22. Flowers are most closely related to A. B. C. Morphology and molecular data
