Galápagos: An Evolving Story
Around 5 million years ago, a series of violent geological events occurred hundreds of miles off the coast of South America in the Pacific Ocean. An area of hot mantle in the Earth’s crust erupted, spewing wave after wave of lava. These built up to form volcanic islands poking up above sea level. The process lasted several million years, resulting in an archipelago of rocky, barren islands inhospitable to life.
