Description

During England's Industrial Revolution, air pollution darkened the bark of trees; it was therefore difficult for predatory birds to see and catch black-winged moths, so the birds ate more white-winged moths. The result was that the moth population shifted more and more toward the black-winged variety. Duplicate the famous “peppered moth” evolution in your lab — students set up environmental trays to collect data.

• A realistic way to demonstrate Darwin's Theory of Natural Selection, industrial melanism and environmental pollution
• Experiment simulates the predator-prey relationship that changed the balance of nature for the light and dark peppered moth
