This worksheet introduces children to the idea of evolution by looking at Charles Darwin’s study of finches on the Galapagos Islands, reportedly one of the key elements behind his theory of natural selection.
It explains that the distance between the islands meant that the birds could not fly from one to another, and therefore could not interbreed. So, over time, the finches on each island would evolve in different ways to suit their habitats and food supplies.
Some had sharper beaks for eating bugs, others strong, sturdy beaks for breaking into nuts, for example.
This worksheet explains how three different types of finches evolved on the Galapagos Islands, then shows images of other birds and asks students to consider why they may have evolved the way they have.
