This simulation allows you to watch natural selection in action. A population of moths will be released in a forest. At the beginning, the population is 50 percent light moths and 50 percent dark. During the simulation, graphs at the bottom will record any changes in the population. The only factor different between the two types of moths is the color of the wings.
Your role in the simulation is that of a predator. Guide the bird with the mouse to the moths. Click on the moth with the mouse to eat the moth. Every time you eat a moth, you will hear the crunch of an exoskeleton.
If you miss the moth, you will hear the bird call. Eat as many moths as possible in the minute you have.
