About

The Galápagos Islands, an archipelago 1,000 km off the coast of Ecuador, are considered one of the world's premier wildlife destinations and the birthplace of evolutionary theory. Darwin's observations of the islands' unique species — including 13 species of finches adapted to different ecological niches — were crucial to his development of the theory of natural selection. The islands' isolation allowed evolution to proceed undisturbed, producing species found nowhere else: marine iguanas (the only seagoing lizard), giant tortoises weighing 300 kg, flightless cormorants, and blue-footed boobies. Because the animals evolved with no natural predators, they show no fear of humans — visitors can walk among them.
