Problem 1: Did you see a shift in the percentage of light and dark moths in the light background? If so, which was more abundant?  If not, why do you think you didn't see the shift?

Problem 2: Did you see a shift in the percentage of light and dark moths in the dark background? If so, which was more abundant?  If not, why do you think you didn't see the shift?

Problem 3: Did you percentages remain the same through all five trials?  Why do you think you got the results you did?

Problem 4: Did the data you collected support your original hypotheses?  Why or why not?

Problem 5: What were the results of Dr. Kettlewell's experiments?  Do your results agree with Dr. Kettlewell's results? 

Problem 6: Based on Dr. Kettlewell's experiments, why are the peppered moths a good example of natural selection?

Problem 7: How did we get the original dark moth?

Problem 8: What is industrial melanism?

Problem 9: What is biological fitness?

Problem 10: Which two scientists proposed the ideas of evolution by natural selection?

Problem 11: In the lab simulation, and in the real experiments of Dr. Kettlewell, what was the selective pressure acting on the peppered moths?

Problem 12: What would you predict would happen to the peppered moth populations if the pollution in the forests were to disappear? Be sure to explain why you predict this will happen.

Problem 13: How and why are mutations important in natural selection?

Problem 14: Grizzly bears and polar bears are very closely related, so much so that they can reproduce to form hybrid offspring. Use your understanding of natural selection to describe how polar bears became a separate classification from the grizzly.

Problem 15: Describe how grizzly and polar bear evolution may be affected by climate change.
