1 ADAPTATION & VARIATION LEARNING OBJECTIVE: EXPLAIN HOW AN ORGANISM’S ADAPTATIONS HELP IT SURVIVE. EXPLAIN HOW VARIATIONS WITHIN A POPULATION AFFECT THE SURVIVAL OF THE POPULATION. EXPLAIN HOW STRUCTURAL ADAPTATIONS ARE USED TO IDENTIFY ORGANISMS.

2 BEHAVIORAL ADAPTATIONS Behavioral adaptations help an organism survive and reproduce.

3 ADAPTATIONS Structural adaptation : Fur color blends in with the surroundings. Kidneys produce concentrated urine. A physical characteristic that allows an organism to survive in its environment A biochemical function that makes an organism better suited to its environment Physiological adaptation:

4 The Octopus uses its tentacles to capture prey Structural adaptation : Physiological adaptation: The Human body’s ability to maintain a constant internal temperature

5 ADAPTATIONS MAY WORK TOGETHER TO ENSURE THE ORGANISMS SURVIVAL! Behavioral A lions ability to stalk and take down prey Structural A lions teeth and claws allow the lion to capture and eat prey Physiological A lions ability to grow teeth and claws

6 THE IMPORTANCE OF VARIATION Variations can affect the survival of a population. During the drought, only the medium ground finches with beaks survived. larger, stronger

7 THE IMPORTANCE OF VARIATION Variations help individuals survive better in their environment. When a species survives and reproduce, the population survives.

8 WHAT IS BEHAVIOR EXPLAIN WHAT CAUSES ANIMAL BEHAVIOR. DESCRIBE INSTINCTIVE BEHAVIORS AND IDENTIFY THE FOUR KINDS OF LEARNED BEHAVIOR.

9 WHAT CAUSES ANIMAL BEHAVIOR? Stimulus: A that causes an organism to react in some way Response: An organism’s reaction to a signal stimulus

10 WHAT ARE THE TYPES OF ANIMAL BEHAVIOR? A response to a stimulus that is performed correctly the first time A response that is based on practice or experience Instinctive behavior Learned behavior Instinctive behavior Instinctive

11 LEARNED BEHAVIORS Learned behaviors result from experience and practice. Pouncing Catching prey Instinctive Learned

12 TYPES OF LEARNED BEHAVIORS Imprinting: Newly hatched or newborn mammals recognize and follow the first moving object they see. Conditioning Trial-and-error learning Insight learning Imprinting

13 CONDITIONING Learning that a particular stimulus or response leads to a good or a bad outcome Response Stimulus

14 TRIAL-AND-ERROR LEARNING Learning to do a behavior through repeated practice The dog attacked a porcupine and learned that the quills are painful.

15 INSIGHT LEARNING Learning how to solve a problem or do something by applying what you already know, without a period of trial and error

16 WHAT IS BEHAVIOR? OVERVIEW Trial-and-error Instinct Conditioning Imprinting Insight learning A dog is taught to salivate when a bell rings. A dog avoids skunks after one encounter. A crow figures out how to use a wire to get food out of a tube. Newly hatched geese follow a human. Cheetahs pounce on prey.
