The Making of the Fittest: Evolving Switches, Evolving Bodies
After the end of the last ice age 10,000 years ago, populations of marine stickleback fish became stranded in freshwater lakes dotted throughout the Northern Hemisphere in places like Alaska and British Columbia. These fish have adapted to a freshwater environment drastically different than the ocean.Play Short Film

110ActivitiesWorksheet for The Stickleback Evolution Virtual LabA worksheet that guides students through The Stickleback Evolution Virtual Lab. The virtual lab lets students learn firsthand the methods for analyzing body structure in stickleback collected from lakes and fossils recovered from a quarry. Students measure, record, and graph their results to discover evolutionary patterns.
