THE GALAPAGOS ISLANDS (600 miles west of Ecuador in the Pacific)
Few would have heard of this archipelago 563 miles west of Ecuador were it not for Charles Darwin's 1835 visit aboard the HMS Beagle, when he was able to observe differences between isolated populations of animals (notably finches), contributing to the ideas expounded in his 1859 book, On the Origin of Species.
