Natural Selection on Beach Mice

In this lesson, students simulate the process of natural selection and its effects on prey phenotype frequencies over multiple generations. Students are provided with four background patterns and many prey pieces in four corresponding patterns. In this way, each prey type is well-camouflaged for one corresponding background, but is less suited to the others in varying degrees. Following several rounds of natural selection simulation, students compare prey phenotype frequencies to those frequencies found using random selection.
