Evolution. Artwork depicting the evolutionary transition from single-celled (unicellular) creatures (left) through fish, reptiles and mammals to modern humans (right). In 1859, Charles Darwin (1809-1882) showed how closely related groups of organisms could have the same evolutionary ancestry and that their divergence was propelled by natural selection, a theory that had far-reaching theological implications.
