Title: Goals and Learning Objectives - chp 32
Course: BIO-182 RTZ > Section: week 8 - Protostome Animals

GOALS:

- Describe the biological features of the major groups of protostomes
- Describe the major groups of arthropods
- Discuss the adaptations that resulted in the great diversity of arthropods

LEARNING OBJECTIVES:

1. List the key defining characteristics of protostomes.
2. Describe the relationship of the cuticle to the exoskeleton.
3. Describe the evolutionary significance of the exoskeleton for arthropods.
4. Describe the biology of ribbon worms.
5. List the defining characteristics of annelids.
6. List the four major clades of mollusks and describe their biological characteristics.
7. Describe the key features that have contributed to arthropod success.
8. Describe the body plan of a common crustacean. Give examples of some common crustaceans.
9. Discuss Terry Erwin’s assumptions about the true diversity of insects.
10. Differentiate between incomplete and complete metamorphosis. Discuss the evolutionary advantages of complete metamorphosis.
11. Compare the wings of dragonflies, true flies, beetles and neopterans.
12. Discuss the factors (adaptations) that lead to the success and rapid diversification of insects on land.
13. List and summarize the importance of six major evolutionary trends of the protostomes that lead to their great diversity and success.
