1. Evolution and Animal Behavior Darwin’s Theory of Evolution

2. Behavior 1) Instinctive –Migrations –Feeding Habits –Mating Rituals 2) Learned -Avoiding predators -Hunting techniques -Locating sources of water

3. What does Darwin say about instinctive behavior? Natural variation in the behavior of animals leads to the development of helpful behaviors which are passed on, and harmful behaviors which die out with the animal http://animal.discovery.com/videos/top-10- bloodsuckers-vampire-finches.htmlhttp://animal.discovery.com/videos/top-10- bloodsuckers-vampire-finches.html http://dsc.discovery.com/videos/life- cheetahs-hunt-ostrich.htmlhttp://dsc.discovery.com/videos/life- cheetahs-hunt-ostrich.html

4. Effect of Environment on Behavior Does the environment force evolution? In what ways?

5. Darwin’s Answer Focus on the variation of behavior rather than the environment. For example, if a new food source is found and is more advantageous to survival then this feeding behavior will be passed on Think about the Vampire Finch

6. Another Example When a goose egg hatches, the gosling must find its mother. What is the gosling’s way of determining where its mother is?

7. Answer The first moving object it sees is thought to be its mother. In captivity this can cause the gosling to think that anything it sees moving first is its mother even if it isn’t.

8. Effects of Other Organisms on Evolution Through predator-prey relationships Competition between species http://news.discovery.com/videos/news-lizards- show-evolution-in-action.htmlhttp://news.discovery.com/videos/news-lizards- show-evolution-in-action.html

9. Altruism Ground squirrels alarm the group of the presence of a predator This doesn’t fit the “survival of the fittest” idea, or does it? Can we think of how this action might be helpful for the squirrel who calls out to protect the others?

10. Cooperation Similarly, cooperation helps animals work together for the sake of the group. This behavior is passed on because cooperation is the best way to survive, those that cooperate survive. http://dsc.discovery.com/videos/planet-earth- shallow-seas-dolphin-waves.htmlhttp://dsc.discovery.com/videos/planet-earth- shallow-seas-dolphin-waves.html http://dsc.discovery.com/videos/planet-earth-ice- worlds-antarctic-penguin-fathers.htmlhttp://dsc.discovery.com/videos/planet-earth-ice- worlds-antarctic-penguin-fathers.html
