Try to behave as a bird would behave, choosing the moths that are the most obvious. At the end of each simulation, record the percent of moths captured in the table below. Final Analysis 22. Explain how the color of the moths increases or decreases their chances of survival. 23. Explain the concept of "natural selection" using your moths as an example. 24.
