Due to the increase of the fork birds there was a decrease in the fork bird's food supply. The 2 tined fork birds in the first generation had a food supply average of 95. The 2 tined fork birds in the fifth generation had a food supply of 57. The 2 tined fork birds in the tenth generation had a food supply of 34. The 1 tined fork birds for generation one was 0. The 1 tined fork birds for the fifth generation had a food supply of 11. The 1 tined fork birds for the tenth generation had a food supply of 18. The 4 tined fork bird had a supply in the first generation of 0. In the fifth generation it was 28. In the tenth generation it was 46. These results show that generation by generation the food supply for every fork bird had to change. The fork birds had to adapt to this change. For example if there is 16 square miles of food supply for these fork birds, in the first generation there were 2 fork birds then they would split the food in half. Through out the generations there are offsprings and their offsprings and they have to change the division of food. The more fork birds there are the less food supply. The 4 tined fork birds, in generation ten were the most successful. Their generation is most successful because a they produced more off-springs, but there wasn't enough food to go around there was less food supply. The Natural Selection of the fork birds is that their beaks kept changing due to the parents genes. In the activity the person (Fork Bird) with the less food (Cheerios) had to change to the number given by the parents. For example if Navjot got the lowest amount of food, and Nicole got the highest amount of food, then Nicole would have to role the die and Navjot would have to be one of the probabilities. If Nicole rolled a 6 then Navjot would have to be a 4 tined fork bird. There won't be many fork birds because it will be hard for them to adapt to their environment after this change. Cheerios was there livelihood and they lost that to due to the permanent extermination of the regular food supply. Having a greater amount of variation of the cheetahs helps them survive, becasue if there are very few cheetahs more predators will try to atack. But if there are a lot of cheetahs the predator might want to step back, becasue the cheetahs will be able to defend eachother.
 * Describe what happened to each type of fork bird over time.
 * Which fork bird was the most successful? Use your data to support your answer.
 * 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?
 * 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.
 * 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?
