| Abstract | Chocolate calms the mind, yet excites the senses. Chocolate also unites cultures. "Chocolat" (2000), a movie about a small town French chocolate shop, made millions internationally. Starring actors contributed partly to the film's success, but the film also drew salivating viewers worldwide to the multiple applications of chocolate. With its stimulant properties, chocolate generally makes people feel good. Chocolate may also inspire creativity. This article talks about the evolution of the chocolate bar as a creative approach to teaching phylogenetic relationships within evolutionary biology. Using chocolate as a "model organism" can make understanding key elements of evolution more palatable to the student. Chocolate represents an ideal model for exploration because it comes in many variations, some of which make good choices for describing evolutionary history and some of which change too much to be useful. In this article, the authors describe an exercise wherein students use a group of candy bars to learn about phylogenetic principles and how scientists work to understand the relationships that exist between organisms. The exercise described is easily assembled, works as a class demonstration, spawns small group projects, fits a variety of class timeframes including labs, and provides for substantial discussion.
