What was the industrial rev- In England, factories were being built.They ran olution? by burning coal for fuel. The result was a dark smoke that covered the surrounding countryside. Trees that had been light and covered by lichens now were dark and bare. 8. What was causing the change in the color of the moths? The trees were now dark and bare.Some think that they changed in naturally others say that they were affected by the chemicals.The genetics in the moths had color and the ones passing the genes were the dark one hence having them pass the genes on. 9. Why would dark moths have The dark months have an advantage with bean advantage? ing able to blend in with the dark trees. 10. What is an entomologist? Entomologists are people who study insects, as a career, as amateurs or both. 11. How do scientists test theories? 1/3 By making predictions based on the theory and then testing the predictions to see if their observation matches the expectation 12. Dr. Kettlewelll predicted that clean forests would have light colored moths, and polluted forests would have dark colored moths. 13. How did Kettlewell test his hypothesis? Dr. Kettlewell placed light and dark moths on the trunks of trees where he could observe them. He recorded the times a bird found the moth. 14.

He found that on dark tree trunks, birds were twice as likely to eat a light moth as a dark moth. 15. Explain how the color of the If their color is the same as their environment moths increases or decreas- their chance of survival increases because the es their chances of survival. predator can't see them and if their color is different from their environment it is opposite. 16.

Predict what would happen if there were no predators in the forest. Would the moth colors have changed? Why or why not? No they would not change because they already had the genetics to change and they would have no need for camouflage from predators and no need to be darker or light. 18.
