Please help 2. What advantages help the peppered moth stay alive from birth to adulthood?

Natural Selection

1. Explain the impact of the industrial revolution on the environment in England.
2.
3. What evidence led scientists to believe that moth color was genetic and passed from parent to offspring?

4. Explain how natural selection influenced the species of moths to change over time.

5. What is industrial melanism?

6. Since the industrial revolution, there have been improved environmental standards and reduced pollution. Explain why the number of light colored moths is increasing.

Dr. Kettlewell

1. Kettlewell tested whether dark colored moths lived in polluted forests and light colored moths lived in clean forests? Explain his test.
2.
3. How did Kettlewell test bird predation on moths?

4. How did Kettlewell test if dark moths lived longer in dark forests?

5. What did Kettlewell conclude based on his results?

Work through the How to Play and then Play the game by working through simulations for both light and dark forests.
After each simulation record how the moth population in your forest changed. Include the percents of both light and dark moth populations.
(table below)
Percent of Light Moths Remaining Percent of Dark Moths Remaining
Light Forest
Dark Forest

1. Explain the theory of Natural Selection in your own words. How did the moth population change over time?

2. What selective pressure drove the moth population to change during the industrial revolution?
