Evolution

The 13 species of finches that live in the Galápagos Islands evolved from a single common ancestor within the past 2 million to 3 million years. Although they may not seem to be all that different from one another, distinct species living on the same island generally keep to themselves and don’t interbreed. What keeps them separate?

This fun activity tests students’ ability to distinguish between two species of finches living on the island of Daphne Major based on how they sound and look.
