Data Analysis - Answer the following questions.
 * 1) Describe what happened to each type of fork bird over time.

According to the graph the 2-Tined fork birds' population decreased over time. The average population started at 95 and ended at 34. The graph also shows that the 4-Tined fork birds start at 0, but ends with 46. This increased over time, but it increased more than the 1-Tined fork bird. The 1-Tined fork bird starts at 0 but ends 18. The 1-Tined fork bird didn't show up much.

2. Which fork bird was the most successful? Use your data to support your answer.

The 4-Tined fork bird was more successful throughout. The 4-Tined started out with 0 but it increased more than the 1-Tined fork bird. The graph shows that the 1-Tined fork bird starts out at 0 but doesn't increase as much as the 4-tined fork bird. Even though the 2-Tined fork bird starts out at a very large number, it decreases over time. At the end, the 2-tined fork bird decreased to a number lower than the 4-Tined fork bird ended with.The graph shows that the 4-Tined fork bird was more successful throughout the generations.

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?

Natural Selection is how adaptation occurs. Over time, the 2-Tined fork birds' population decreased. This is because their structure wasn't well adjusted with their habitat. The 4-Tined fork bird was more successful as time passed because their population increased. It was easier for the 4-tined fork birds to capture their food (the cheerios) because they had 4 tines to help them support. It was more suitable for them to have 4 tines in their habitat. Eventually over time, they adapted to their setting.

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.

After a few generations have passed, the population of the fork birds will decrease because some of the birds won't be able to adapt to the change very quickly. When more generations have passed, the population will start to increase again because the birds that were able to adapt, will now mate and produce more offsprings. Overtime, the appearance of the fork birds might change. Humans respond to the change of food. For example, when humans eat junk food, they gain weight and start to get sick. When they eat healthy food they stay healthy and happy. The same way, fork birds might respond to the change of food also.

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?

The little variation in the cheetahs shows how they are on the verge of becoming extinct because for every species there are different types of each animal. Since there isn't much variation between the cheetahs that are alive today, this shows how those genes are not being passed, therefore there are not many left. In other words cheetahs are endangered animals.
