 Evolution
An enjoyable and educational simulation of natural selection through a game of predator and prey in camouflaged butterfly populations. This lab is based on a game invented by G. Ledyard Stebbins, a pioneer in the evolution of plants. The purpose of the game is to illustrate the basic principles and some of the general effects of evolution by natural selection. The students take turns acting as predators of butterflies camouflaged on various patterned cloth backgrounds. The butterflies are played by colored dots that the students can make with a hole punch and a few sheets of colored cardstock. The change in the number of color variants is measured from generation to generation. Fun. Simple. Instructive.
