Charles Darwin's theory of evolution and natural selection has been debated and disparaged over time, but there is no dispute that he is responsible for some of the most remarkable and groundbreaking scientific findings in history. His five-year trip as a naturalist on the H.M.S. "Beagle"took him on a journey to such exotic locales as Chile, Argentina, and the Galapagos Islands. Darwin wrote the details of this expedition, including his thoughts about the people on the ship and of course, his observations of the flora and fauna, in his journal, published as "Voyage of the Beagle." It is here that his original interpretations of the Galapagos ecosystem and the impact of nature and selection are first revealed.

This edition of the classic travel memoir is enhanced with an introduction by bestselling nature writer David Quammen, and is part of National Geographic's major cross-platform event in spring 2009 to celebrate the anniversary.
