    The famous scientist and thinker, Charles Darwin, was born on February 12, 1809. As a boy, Charles liked to go for walks in the fields and forests. He enjoyed watching nature, and comparing what he saw with everything he had read in science books.

    At sixteen, Darwin was sent to Edinburgh University to become a doctor. But he was interested in the history of nature. Then he was sent to study in Cambridge University. He left the university in 1831. Some time later he heard that the ship Beagle was going on a trip to South America and wanted a scientist. His teacher advised him to go. So when the Beagle left England in December, 1831, Darwin was on it. The trip lasted almost five years.

    In 1842 Darwin went to live in Ken. Darwin understood that plants and animals are not always the same, and that they really change. By 1859 Darwin had finished his famous book "The Origin of Species". Darwin continued his studies in science before he died in 1882.
