Introduction

The peppered moth is a species of moth that has played a significant role in evolutionary biology. This species is known for its ability to adapt to changes in its environment, particularly in response to pollution. The peppered moth simulation worksheet is an educational tool that allows students to explore the mechanisms of natural selection and adaptation. In this article, we will provide the answer key to the peppered moth simulation worksheet.

The Peppered Moth Simulation Worksheet

The peppered moth simulation worksheet is a set of questions and activities designed to help students understand the process of natural selection. The worksheet includes a series of scenarios that simulate the changes in the environment and the corresponding changes in the peppered moth population. The scenarios include the following:

Scenario 1: The Original Population

In this scenario, the worksheet describes the original population of peppered moths in a forest. The moths are described as having a light-colored body with speckled markings.

Scenario 2: Industrial Pollution

This scenario describes the impact of industrial pollution on the environment. The worksheet explains that the pollution has caused the trees to become darker in color, which has made it easier for birds to spot the light-colored moths.

Scenario 3: Natural Selection

In this scenario, the worksheet describes how natural selection has allowed the peppered moth population to adapt to the changes in the environment. The worksheet explains that the darker-colored moths are better camouflaged in the polluted environment, which has allowed them to survive and reproduce.

The Answer Key

Now that we have introduced the peppered moth simulation worksheet, let’s take a look at the answer key.

Scenario 1: The Original Population

Question 1: What is the color of the peppered moth’s body? Answer: The peppered moth has a light-colored body with speckled markings.

Scenario 2: Industrial Pollution

Question 1: What impact has industrial pollution had on the trees in the forest? Answer: Industrial pollution has caused the trees to become darker in color. Question 2: How has the change in the trees affected the peppered moth population? Answer: The darker trees have made it easier for birds to spot the light-colored moths, which has decreased their survival rate.

Scenario 3: Natural Selection

Question 1: How has natural selection allowed the peppered moth population to adapt to the changes in the environment? Answer: Natural selection has allowed the darker-colored moths to survive and reproduce because they are better camouflaged in the polluted environment. Question 2: What is the process of natural selection? Answer: Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce.

Conclusion

The peppered moth simulation worksheet is an excellent tool for teaching students about natural selection and adaptation. By understanding the process of natural selection and how it applies to the peppered moth population, students can gain a deeper appreciation for the mechanisms of evolution. We hope that this article has provided you with the answer key to the peppered moth simulation worksheet and helped you understand the importance of this educational tool.
