Charles Darwin and the theory of Evolution Charles Darwin and the theory of Evolution CHARLES DARWIN AND THE THEORY OF EVOLUTION It is commonly thought today that the theory of evolution originated from Darwin in the nineteenth century. However, the idea that species mutate over time has been around for a long time in one form or another. Therefore, by Darwin's time the idea that species change from one type into another was by no means new, but was rejected by most because the proponents of evolution could not come up with a satisfactory mechanism that would explain this change. The most influential evolutionary theories prior to Darwin were those of Lamarck and Geoffroy St. Hilaire, developed between 1794 and 1830. Lamarck suggested that species evolve through the use or disuse of particular organs. In the classic example a giraffe that stretches its neck slightly to reach higher leaves will gain in neck length, and this small gain would be passed on to its offspring. Geoffroy, on the other hand suggested that the change was discontinuous, large in magnitude, and occurred at the production of offspring. However, these theories of evolution were based on a priori explanations that offered no demonstrated mechanism. Darwin's theory of evolution differs in that it is based on three darwin, selection, evolution, natural, darwin's, theory, species, time, origin, one, sexual, book, struggle, later, ideas, however, because, therefore, published, man, been, voyage, scientific, rather, population, malthus, first, existence, books, work, suggested, new, means, life, journal, idea, change, animals, about, years, thought, science, principle, out, offspring, notebook, just, important, england Word Count: 3527 Acceptance_Essays American_History Anatomy_&_Physiology Animal_Science_&_Zoology Anthropology Architecture Art Astronomy Aviation Biographies Book_Reports Business Computers Creative_Writing Current_Events Economics Education Engineering English Environmental_Science Ethics European_History Film_&_TV Foreign_Languages Geography Government_&_Politics Health_&_Beauty History_Other Human_Sexuality Legal_Issues Marketing Mathematics Medicine Miscellaneous Music Mythology Philosophy Physics Poetry Political_Science Psychology Religion Science Shakespeare Social_Issues Sociology Speech Sports_&_Recreation Supernatural Technology Theater Theses_&_Dissertations
