| Site Map | The Controvertial issue: Darwin's Theory vs Theology Darwin cautiously introduced the theory of evolution in 1858. The theory stated that all species evolved from a few common ancestors by means of natural selection. He set forth his theory in The Origin of the Species in 1859. Darwin was fascinated by the variety of species on the Galapagos Islands, and also the differences between the islands. He concluded, after rejecting previous theories, that environmental factors, as well as natural selection, allowed a specie to evolve over a period of time. |
