A Warming Planet Jolts the Iconic Creatures of the Galápagos
Species that inspired Darwin’s theory of natural selection are facing new challenges to adapt.
Jon Witman checks his air gauge, adjusts his flippers, and falls backward into the Pacific. Nearby, the ocean throws itself against Isla Beagle, one of a hundred-plus rocks, pinnacles, and islands that form the Galápagos archipelago, a province of Ecuador that straddles the Equator. Rebuffed, the sea retreats in a white flag of foam.
On a shelf above the spray, blue-footed boobies dance with the awkwardness of teens at a junior high prom. Below them on the rocks, an argument breaks out between two Galápagos sea lions. The scene could have looked and sounded the same when Charles Darwin sailed here almost two centuries ago. These creatures, fine-tuned to life on harsh isles, seemingly can weather anything, even time itself.
