Simulating Environmental Changes
The simulation mimics environmental shifts, such as pollution levels affecting tree bark coloration. Participants adjust variables to observe how darker or lighter moths thrive, reflecting real-world ecological impacts. This interactive approach demonstrates how industrialization influenced moth population dynamics, with pollution favoring darker moths for camouflage, thus illustrating natural selection processes in action.
Role of Predators in Natural Selection
Predators, such as birds, drive natural selection by preying on moths based on visibility. Participants act as predators, selecting moths that stand out against pollution-altered backgrounds. This mimics how environmental changes favor certain traits, leading to population shifts and illustrating adaptation through predation pressure.
Recording Observations and Data
Participants systematically record moth population changes, noting light and dark moth percentages. Data collection highlights how environmental factors like pollution influence survival rates.

Expected Outcomes and Trends
The simulation predicts a noticeable shift in moth population dynamics. In polluted environments, darker moths are less visible, leading to their increased survival and reproduction. Conversely, lighter moths dominate in unpolluted areas. Over generations, natural selection drives these trends, reflecting adaptive responses to environmental conditions and predator interactions.
Interpreting Data on Moth Populations
By analyzing data, participants observe shifts in moth coloration percentages. Darker moths thrive in polluted environments, while lighter moths dominate cleaner areas. This data illustrates natural selection’s role in population dynamics, showing how environmental pressures influence species adaptation and survival over time.
Assessing the Role of Natural Selection
The simulation highlights natural selection by demonstrating how environmental factors, such as pollution, influence moth survival. Darker moths thrive in polluted areas, while lighter moths dominate cleaner environments, illustrating how adaptive traits become prevalent.
