Charles Robert Darwin was born on February 12, 1809 in Shrewsbury, England. Darwin was the British naturalist who became famous for his theories of evolution and natural selection. Like several scientists before him, Darwin believed all the life on earth evolved over millions of years from a few common ancestors.
From 1831 to 1836 Darwin served as naturalist aboard the H.M.S. Beagle on a British science expedition around the world. In South America Darwin found fossils of extinct animals that were similar to modern species. On the Galapagos Islands in the Pacific Ocean he noticed many variations among plants and animals of the same general type as those in South America. The expedition visited places around the world, and Darwin studied plants and animals everywhere he went, collecting specimens for further study.
Upon his return to London Darwin conducted thorough research of his notes and specimens. Out of this study grew several related theories 1. evolution did occur; 2. evolutionary change was gradual, requiring thousands to millions of years; 3. the primary mechanism for evolution was a process called natural selection; and 4. the millions of species alive today arose from a single original life form through a branching process called ‘specialization.’
Darwin’s work had a tremendous impact on religious thought. Many people strongly opposed the idea of evolution because it conflicted with their religious convictions. Darwin avoided talking about the theological and sociological aspects of his work, but other writers used his theories to support their own theories about society. Darwin was a reserved, thorough, hard working scholar who concerned himself with the feelings and emotions not only of his family, but friends and peers as well.
Darwin’s theory of evolutionary selection holds that variation within species occurs randomly and that the survival or extinction of each organism is determined by that organism’s ability to adapt to its environment. He set these theories forth in his book called, The Origin of Species. After publication of Origin of Species, Darwin continued to write on botany, geology, and zoology until his death in 1882. He is buried in Westminster Abbey.
