HMS Beagle set sail from the Plymouth Sound, England, on 27th of December 1831.
This expedition was to change not just the views and life of Charles Darwin but was to have the most profound implications for the way Humans thought of themselves and of their planet.
Charles Darwin was 22 when the voyage started. His role was one of a scientific nature. For nearly 5 years HMS Beagle plied the seas of the globe. You can read more about that here: The Beagle Voyage
On his return Captain Fitzroy published his book about the voyage to which Darwin contributed. Accounts like this were very popular in Victorian Britain and the publisher issued in 1839 Darwin’s Journal of Researches. Later editions also followed.
