Animal Behavior 2009, 13 rebmevoN  Objective:  SWBAT explain how animals respond to selected stimuli  SWBAT explain how behavior leads to survival to the species  Catalyst:  How do analogous structures support evolution?  How do homologous structures support evolution?  How do transitional fossils support evolution?

Agenda  Catalyst  Big theme of today  Phototropism  Cuckoo Birds

Behavior  What am I talking about?  Talking during class?  No, but stop it.  Behavior is the response to internal and external stimuli by an organism  Stimulus- something that causes a behavior

Animal Behavior  Key Point #1:  Organisms respond to stimuli in a way to increase their fitness in their environment

Big theme of today  How does the behavior increase the survival of itself or its species?  I will give you 5 examples. After each, I want you to write a couple of sentences about why this behavior increases the chances of survival for itself or the species. This is your classwork for the day

Plant Behavior???  Phototropism- Growth of plant in response to light  Many plants will grow towards the direction of the light Light-Left No light All around Light

Phototropism  Why would a plant go through phototropism?  Journal #1:  Explain how plants react to the stimulus of light.  Explain why this behavior increases fitness in this environment.

Types of Behavior  Key Point #2:  There are two general types of behaviors: innate and learned.  Innate behavior- behaviors under genetic control Instincts  Learned behavior-behavior that occurs because of experience

Brood Parasitism  A type of parasitism where an organism tricks another into raising its young  Cuckoo video  Journal #2:  What are TWO examples of innate behavior in this video?  Does the mother laying the egg in the other bird’s nest increase the survival of the species? How?

Learned Behavior: Imprinting  Imprinting- Rapid learning that occurs at young age during a critical period of development.  Humans have a certain age where they need to be exposed to sights and sounds otherwise they will lose the ability to see and hear  Baby geese (and other birds) imprint the first thing they see as their mother and follow her (or it) around after that

Fly Away Home  Journal #3:  Why is imprinting a learned behavior?  Why does this behavior increase fitness?

Migration  What happens in this movie?  Is this learned or innate?

Insight  Insight – the ability to solve unfamiliar problems in a new situation  Ex: Chimpanzee and Bananas

Didn’t find that video…  Look at insight in pigeons in a similar task  Journal #4:  Why is this behavior a learned behavior? Why does it increase fitness?

Territorial Behavior  Territorial behavior- Animals try to protect their territory to enhance survival. Sometimes it occurs over food, shelter, or mates

Kangaroos  Eastern Grey Kangaroos have a system where there is one dominant male. This one dominant male mates with most of the females around, because it proved to be the most powerful. Sometimes, as the dominant kangaroo ages, challengers will come to try and take the dominant spot…  Kangaroo battle video

Stop and Jot it Like its Hot  Journal #5:  Why would kangaroos go through the stress of fighting?  What happens to the losing kangaroos?

Exit Question  Pick one of the 5 behaviors we saw today. Explain why this behavior increases fitness in that environment.
