Notes

Summary
In 1831 22-year-old Charles Darwin took at job as companion/naturalist to an equally youthful sea captain on a round-the-world surveying journey. For five years he sailed the seas. He had adventures, noticed everything, and wrote it all down. He collected animals and fossils; he experienced earthquakes and volcanoes; he met people of many cultures - and had opinions on them all. And, being the remarkable person that he was, he put his observations (and some reading) together to come up with an explanation for the way life on Earth changes.
