Chapter 47 Outline

Animal Behavior

The genetic basis of development is discussed in relation to changes in behavior over time which includes the development of a behavioral pattern and its adaptiveness. The evolutionary concept of fitness also helps explain how animals interact in societies.

Chapter Outline

In this chapter outline, the learning objectives and the selected key terms are given for each major head in the chapter.

1. Describe the two types of questions considered by biologists who study animal

behavior.

Selected Key Terms: behavior

Behavior Has a Genetic Basis (p. 826)

2. Support, with examples, the premise that behavior has a genetic basis.

3. State, with examples, the two body systems that control behavior.

Behavior Undergoes Development (p. 828)

4. Give examples to show that behaviors sometimes undergo development after

birth.

5. Discuss different types of learning and how learning affects behavior.

learning, operant conditioning, imprinting Behavior Is Adaptive (p. 830)

6. Explain why you would expect behavior to be adaptive.

7. Discuss sexual selection in relation to male competition and female selectivity

for mates.

8. Show how an animal's way of capturing resources may be related to its

reproductive behavior.

9. List and give examples of the different types of communication between

animals.

sexual selection, dominance heirarchy, territoriality

Animals Are Social (p. 833)

10. Use a cost-benefit analysis to show that social living is sometimes

adaptive.

society, communication, pheromone

Sociobiology and Animal Behavior (p. 835)

11. Explain how altruism might evolve under certain circumstances.

sociobiology, altruism, inclusive fitness
