5. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Section 1 Evolution of Behavior Objectives Distinguish between “how” and “why” questions about behavior. Describe how natural selection shapes behavior. Compare innate and learned behaviors. Summarize how behavior is influenced by both heredity and learning. Chapter 36

6. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu What is Behavior? A behavior is an action or series of actions performed by an animal in response to a stimulus. Scientists studying behavior investigate “how” questions and “why” questions. “How” questions are about how a behavior is triggered, controlled, and performed. “Why” questions seek to identify the benefits of a particular behavior.

9. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Genetically Influenced Behavior Many kinds of animal behaviors are influenced by genes. Genetically programmed behavior is often called innate behavior or instinct. A fixed action pattern behavior is an innate behavior that always occurs the same way.

Evidence that many behaviors have a genetic basis comes from studies in which two types of birds were interbred. The hybrid offspring showed nesting behaviors that resembled those of both parents.

13. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Learning and Behavior The development of behaviors through experience is called learning. Learning can influence the expression of innate behavior and the expression of behaviors that are not innate. Habituation is one simple kind of learning. In habituation, an animal learns to ignore a frequent, harmless stimulus. Section 1 Evolution of Behavior Chapter 36

14. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Learning and Behavior, continued Classical Conditioning A more complex type of learning is conditioning, or learning by association. A type of conditioning in which an animal comes to associate an unrelated response with a stimulus is called classical conditioning. Section 1 Evolution of Behavior Chapter 36

When trial-and-error learning occurs under highly controlled conditions, it is called operant conditioning. Section 1 Evolution of Behavior Chapter 36

17. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Learning and Behavior, continued Reasoning The ability to analyze a problem and think of a possible solution is called reasoning. Reasoning involves using experience to develop an insight into how to solve a new problem. Humans and other primates show the ability to reason. Section 1 Evolution of Behavior Chapter 36

Imprinting cannot be changed once it occurs. Section 1 Evolution of Behavior Chapter 36

Biologists have classified the behaviors animals perform into several broad categories. Chapter 36

Animals display different kinds of foraging behavior. Generalists consume many different kinds of food. Specialists feed primarily on one kind of food. Section 2 Types of Behavior Chapter 36

26. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Reproductive Behavior When ready to mate, animals produce signals to communicate with potential partners. Each animal species usually produces a unique courtship signal that ensures that individuals do not mate with individuals of another species. Section 2 Types of Behavior Chapter 36

27. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Reproductive Behavior, continued Mate Choice In many animals, the female evaluates the male before she decides to mate, a behavior called mate choice. In some animal species, males have extreme characteristics that they use in their courtship displays. These extreme traits help males attract or acquire mates. Sexual selection is selection in which a mate is chosen based on a certain trait or set of traits. Section 2 Types of Behavior Chapter 36
