In this activity, students examine research on finches on the island of Daphne Major in the Galapagos Islands. The depth of the finches' beaks was measured before and after a drought. This data is displayed in graphs and students are...

This graphic from Ecology and Evolution of Darwin's Finches by Peter Grant presents data from the Galapagos Islands, showing that a severe drought put selective pressure on the population of Darwin's finches and resulted in a change in...

This lesson plan explores how natural selection has influenced the development of features that contribute to successful feeding (bills, wings, talons, etc.), as well as identifying those characteristics that enable birds to obtain the...

Instructional module focusing on Charles Darwin's theory of Descent with Modification. Discusses how slight changes from parent to offspring create variation and potentially create new species over time. Site also includes an interactive...

In this biology activity, students will be investigating evolution by "competing" for food like Darwin's finches might have competed. Each student group is given a different type of "beak" to work with and there are also different kinds...
