One of the basic requirements of evolution is variation in a population upon which selection can act. One of the sources of variation is mutation in DNA. These changes may or may not be reflected in the ensuing amino acid sequence of a protein. This exercise explores the additive effects of mutation on an amino acid sequence over several generations. The activity is also useful in that it addresses several of the components of Darwin’s theory of evolution through natural selection. There are three separate activities, one regarding sequence change over time, one regarding selective pressure on sequences, and one regarding divergence over time.
