In 1831, Charles Darwin sailed to South America aboard the H.M.S. Beagle. On the return voyage across the Pacific, the vessel stopped on a small group of islands far off the Ecuadorian coast, changing the course of human scientific endeavour and self-understanding forever. Fascinated by the unique wildlife on the islands, Darwin collected biological specimens and studied them over the next 30 years. His findings led to the formulation of the scientific theory of evolution by natural selection. This small group of islands and their one-of-a-kind wildlife are to thank for one of humanity's most remarkable discoveries. And today, almost 200 years later, they remain a source of endless fascination and a favourite travel destination for scientists, nature and wildlife enthusiasts, scuba divers, and anyone interested in the wonders of the natural world.
