Fork Bird Questions

1. Describe what happened to each type of fork bird over time? Over time the fork birds have been decreasing and increasing. As you can see on the line graph that I have made. The one tined fork bird has been increasing form a zero to a high twenty. The two tined bird has been decreasing from a high 90 to a low 30. The four tined bird has been increasing from a zero to a high forty.

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

The 4 tined birds were more successful because at generation 10 it had a much more population between 2 tined and 1 tined birds.

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 is?

Based on what on my data and questions 1 and 2, I think that Natural Selection is how well a group of species adapt to different environmnents and how they survive in different environmnets.

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 forkbirds will be purplish blue because after eating the blueberries the color of the fruit goes to the blood and then the fork bird turns blue/purple. Also, the fork bird is fat/round because the food they eat (blueberries) are round and fat. The only type of fork birds left is the 4 tined forkbirds because it is very easy for them to eat the food.

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?

I think the cheetahs are endangered because they have only a few of there kind and not enough genders to mate with. Also, maybe the cheetahs are not being able to adapt to there new environments.
