Understanding the Peppered Moth Simulation
What Is the Peppered Moth Simulation?
The peppered moth simulation is an educational activity designed to demonstrate the principles of natural selection. It typically involves a virtual or physical model where students simulate the survival of moths with different coloration patterns—light and dark—amidst changing environmental conditions. The simulation helps illustrate how certain traits become more or less common over generations based on their adaptiveness.
Key features of the simulation include:
- Representation of moth populations with varying color morphs.
- Environmental scenarios such as soot-covered trees (industrial revolution) and clean trees (post-industrial era).
- A process of predation where predators favor certain moth types based on camouflage.
- Tracking changes in moth populations across multiple generations.
Why Is It Important?
The simulation exemplifies core evolutionary concepts:
- Natural selection: how environmental pressures influence survival.
- Genetic variation: the importance of genetic diversity for adaptation.
- Evolution in action: observable changes over relatively short periods.
Using the simulation allows students to visualize these processes, bridging the gap between theoretical knowledge and real-world biological phenomena.

Sample Questions and Answers from the Peppered Moth Simulation
Sample Question 1: Why did the frequency of dark-colored moths increase during the industrial revolution?
Answer: During the industrial revolution, pollution caused tree bark to become darkened by soot. Dark-colored moths, due to their camouflage, were less visible to predators compared to light-colored moths. This increased survival rate led to a higher frequency of dark moths in the population, demonstrating natural selection favoring darker coloration.
Sample Question 2: What environmental changes led to the reversal of this trend in modern times?
Answer: As pollution controls reduced soot levels and trees returned to their lighter coloration, light-colored moths once again had better camouflage. Consequently, predators could more easily spot darker moths, reducing their survival rate. Over time, this led to a decline in dark moths and a resurgence of light moths, illustrating how environmental changes influence evolutionary dynamics.
