• On December 27, 1831, HMS Beagle set sail from Plymouth, England, on an around-the-world voyage to survey the coast of South America. The purpose of the expedition was to collect hydrographic information, such as ocean depths, currents, temperature, reefs, and sandbars. It was the Beagle’s second voyage of exploration.

    The Beagle’s captain, Robert FitzRoy, regretted not having a geologist onboard the Beagle’s first voyage, and actively recruited “a person qualified to examine the land; while the officers, and myself, would attend to hydrography.” This naturalist would not be a member of the crew—he would have to pay his own way—but would have unrestricted access to the exotic flora and fauna of South America, as well as shipboard privileges such as his own cabin.

    Charles Darwin, 22 years old, was not FitzRoy’s first choice as the Beagle’s naturalist. But the young scholar was affable, available, and took advantage of the opportunity to rewrite modern science.
