"Telephone" Game Demonstrates the Dobzhansky-Muller (DM) Model of the Evolution of Reproductive Incompatibility

This resource provides an outline for planning and implementing an active learning activity that illustrates the DM model of reproductive incompatibility.

Students in a larger class (50+) whisper sentences to one another in a modified game of "telephone." The lineage of sentences splits and diverges, and students record versions of sentences on notecards as the sentence evolves. After lineages finish evolving, students analyze how the sentences changed, how they relate to one another, and how the result relates to the DM model of reproductive incompatibility.
