In science, we learned that Charles Darwin made the theory of natural selection. He made this theory when he went to the Galapagos Islands. He notice that a bird called the Finch was different than the ones he saw. He noticed that the Finches had different beaks than others. Charles Darwin set out to find out why this happened. In the desert, he noticed that Finches there had a different beak to peck at cactus. He noticed how hot it was and thought that the Finch had adapted to the environment.

Then he met a person named Lyell. Lyell said that the Earth is older than they originally thought. He said that living things probably changed over time. This made Charles Darwin think that the animals had evolved over time. Since the Earth was older, the animals must have evolved. This help Charles Darwin formulate a theory of natural selection.
