Explain #21 Who was Charles Darwin? What was his theory of evolution? What is natural selection? #22 Why do you think earthworms are beige and not green #23 lab write up 96 #24 Cheetahs are very fast. They are endangered.

Why or why not? Lab write-up- what you did, how you did it and incorporate a discussion of your results. Include a graph of the class data for each type of forkbird over many generations. You can plot the data for all three types of forkbirds on a single graph. Be sure to title your graph, label the axes, and provide a key. Include the answers to the following questions in your essay on this lab. 1. Which type of forkbird was initially the most common? 2. What happened over the generations? 3. Which type of forkbird would you consider the most successful? 4. In what way(s) was your prediction similar to the class results? In what way(s) was your prediction different? What could explain the difference(s) between your prediction and the data we collected? 5. What is the source of the physical variation in the forkbird population? 6. How does (inheritable) variation arise in any population? 7. Why must variation be present in the population in order to simulate natural selection? 8. If a forkbird broke one of its tines (or if a real bird chipped its beak), and then reproduced, what would its offspring look like?
