Charles Darwin: a life in pictures
This colour map is from the John Murray 1890 illustrated edition.
From 1831-1836 Darwin sailed around the world as naturalist on the Beagle (not as the captain's gentleman companion as often claimed.) On this persistent myth, see John van Wyhe, '"my appointment received the sanction of the Admiralty": Why Charles Darwin really was the naturalist on HMS Beagle'.
See Darwin's notes from the voyage here and a complete itinerary of every day of the voyage here.
