*Darwin, Charles: * - CHARLES DARWIN (1809-1882), English scientist, naturalist, and geologist, revolutionized science, especially biology, with his theory of evolution through natural selection. As a passenger aboard the Beagle, Darwin became intrigued by the existence of different species in different geographical locations, which aided in the development of his theory. In addition to The Origin of Species, he is also remembered for The Voyage of the Beagle, and The Expression of the Emotions in Man and Animals.
