... prey–predator coevolution in escape/pursuit speed. It illustrates how selection pressure on individual speed increases average population speed through differential survival, while also reducing variation in speed among individuals. A simulated beneficial mutation helps differentiate the generation of...

In this guided investigation of evolutionary mechanisms, students use LEGO bricks to simulate how mutation, migration, genetic drift, and natural selection can affect the evolution of a population. This exercise was undertaken and assessed with college introductory biology students...
