Why it is important that scientists discovered that color was genetic? f. What caused the dark color in the moths? Could this be passed on to the next generation? g. What didn’t this explain about moths? h. Why did J.W. Tutt propose that natural selection was the cause of the change in color of the moth population? i. What is industrial melanism? 4. Click on Kettlewell’s experiments . Read about these experiments and answer the following question.

5. Click on Bird’s Eye View. Read about the simulation. What is the population of light and dark moths at the beginning each simulation? 6. You are your partner should each take turns playing the simulation with the light colored background first and then with the dark colored background (this will give you two trials for each type of background). Record how many light and dark moths were after each simulation and find your averages. Light Background: Dark Background: How does the simulation model natural selection? After each simulation think about traits that will be passed on to the next generation. 7. Examine the table and construct a properly formatted graph (Use lab Format) on a separate sheet of paper. You should have 2 lines on your graph - one for light moths, and one for dark moths. # of moths captured Year # of light moths captured # of dark moths captured 2 537 112 4 392 210 6 225 337 8 147 503 10 56 599 8. Explain in your own words what the graph shows. What type of environment do you think these moths live in?
