Charles Darwin's theory of evolution by natural selection was in large part formed by his observations on the Galapagos archipelago in 1835. The island chain is in the Pacific Ocean roughly 972 kilometers west of Ecuador and houses a variety of exotic species including the Blue-footed Booby which has large blue foot that are shown off during courtship. The Galapagos Islands are also home to the the only living tropical penguins, the appropriately named Galapagos Penguin.
