Award-winning cultural historian Iain McCalman tells the stories of Charles Darwin and his staunchest supporters: Joseph Hooker, Thomas Huxley, and Alfred Wallace. Beginning with the somber morning of April 26, 1882—the day of Darwin's funeral—Darwin's Armada steps back and recounts the lives and scientific discoveries of each of these explorers, who campaigned passionately in the war of ideas over evolution and advanced the scope of Darwin's work.
