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 asked to interpret these during a slideshow presentation. They learn that some finches did not survive the drought and that a higher percentage of finches have developed deeper beaks because they had to adapt to a change in their diet.
