"During one of his explorations, naturalist Charles Darwin reached the Islands of the Galapagos".
He observed that there are the same species of animals on different islands, but have noticeable differences. He found in Galapagos, that there were finches, a type of bird, with different type of beaks. Birds used their beaks to acquire food. It led him to discover that species developed over time to fit their way of life in surviving and getting their food.
