But the voyage of the Beagle was the turning point in Darwin's life. It gave a breadth and depth to his experience that was invaluable to his later thinking. During the five-year journey of the Beagle (1831-1836), Darwin spent only 18 months at sea. His curiosity, coupled with his frequent bouts of seasickness, inspired him to take long expeditions exploring the natural history and geology of Sough America, the Galapagos Islands, Tahiti, and Australia. Darwin made careful observations and looked for patterns wherever he went. His key observations about the diversity and distribution of species spurred his thinking for On the Origin of Species by Means of Natural Selection.
Darwin wrote letters to his mentors and sent his collections home throughout his journey. By the time Darwin stepped of the Beagle, he was already recognized by the scientific community for his expertise.
Darwin spent 20 years gathering evidence and writing about his theory before he published it. He anguished over the controversy it would create in Victorian England. And, if the naturalist Alfred Wallace hadn't come to similar conclusions and written to Darwin for help in presenting them, it might have been even longer before the world heard about On the Origin of Species.
