On December 27, 1831, Charles Darwin, naturalist on board the HMS Beagle, had embarked on a five-year scientific survey of South American waters to study the flora, fauna, and geology of Tenerife, the Cape Verde Islands, Buenos Aires, Valparaiso, the Galapagos, Tahiti, New Zealand, Tasmania, and finally the Keeling (Cocos) Islands. The evidence he gathered forced him to deny Paley’s argument from design. God had certainly not created the world exactly as we knew it. Instead, it seemed clear that the species had evolved slowly over time, as they adapted to their immediate environment.
