= Graph the following: = = :) _ Initial Fork Bird Population :) _ 5th Generation Fork Bird Population :) _ Final Fork Bird Population :) _ Include 1, 2 and 4 tined fork birds :) _ Graph should be a line graph with three different lines :) _ Embed Graph in your Science Wikispace = = = = = =Data Analysis - Answer the following questions. = = 1. Describe what happened to each type of fork bird over time. = =The 2 tined fork bird population got smaller and smaller. For example, In the first generation, there was 95 2-tined fork birds. In the 5th generation, there was 57 2 tined fork birds; and in the last generation, there was 34 2 tined fork birds. Unlike the 1 tined fork bird population which got larger. For example, in the first generation, there was 0 1 tined fork birds. In the 5th generation, there was 11 1 tined fork birds;and in the last generation, there was 18 1 tined fork birds. The 4 tined population also increased. In the first generation, there was 0 4 tined fork birds. IN the 5th generation, there was 28 4 tined fork birds; and in the last generation, there was 46 4 tined fork birds. Within the 10 generations, the 2 tined population decreased and the 2 tined[and] 4 tined population increased.= = 2.Which fork bird was the most successful? Use your data to support your answer. = =The 4 tined fork bird was the most successful because their population grew the most.= = //3.Battling Beaks //simulates the idea of **NATURAL SELECTION. **Based on what you did in class, your data and questions 1 and 2, what do you suppose natural selection? = = I think natural selection is the process of how organisms evolved to adapt to the environment. With the work of the fork bird experiment, I was able to see the adaptation of the fork birds. They could evolve from a 2 tined fork bird to a 4 tined fork bird to adapt to the environment. = =   = =4.As a result of heavy rains, the major food source for fork birds is now blueberries. After many generations, how many types of fork birds do you think there will be? What will the fork birds look like? Explain your answer. = =I think the fork birds would evolve to spoon birds because of the need to adapt to the environment. I would be easier for them to eat blueberries with a spoon shape body then to eat the blueberries with a fork shaped body.= = 5.The cheetah, an extremely fast and efficient hunter, is an endangered species. The few cheetahs alive today show very little variation. How does this help to explain why cheetahs are on the verge of becoming extinct? = =  Within the many generations that cheetahs have roamed the earth, they did not evolve and adapt to the different environments they now live in. Cheetahs now live in dry places. They have not adapted to the different life styles that are needed for them to live. = = = = =
