Tell students that in this activity they are going to engage in a simulation to learn how selective pressures can affect an organism's evolution. Review with students the concepts of gene, gene pool, selective pressure, mutation, species, and genetic isolation (see Activity Answer for definitions). Tell students that they will make a deck of cards that will represent the entire gene pool for a hypothetical group of genes responsible for temperament in a population of wolves.
