Galápagos Islands

The islands that changed our understanding of life on earth — the Galápagos Archipelago, 1,000 kilometres off the coast of Ecuador in the Pacific Ocean, inspired Charles Darwin’s theory of evolution by natural selection after his visit in 1835, and today remains the finest natural laboratory for observing evolution in action, with species found nowhere else on earth including the only marine lizard and the world’s only equatorial penguins.
