Charles Darwins Theory of Evolution Essay -- Natural Selection, Evolu

IntroductionIt is unremarkably thought today that the speculation of evolution originated from Charles Darwin in the nineteenth century. However, the creative thinker that species mutate over condemnation has been around for a long date in one form or another. Therefore, by Darwins time the idea that species change from one type into another was by no means new, but was rejected by most beca intake the proponents of evolution could not come up with a satisfactory mechanism that would explain this change. exactly how did Darwin come up with an acceptable theory of evolution, and how did Darwins proposal of indwelling selection impact the theory of evolution? The answer lies in the body of work of the works of others, and in the works of Darwin himself, through his theories, his travels and his scientific pioneering. The most powerful evolutionary theories prior to Darwin were those of Lamarck and Geoffrey St. Hilaire, developed between 1794 and 1830. Lamarck suggested that s pecies 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 contact in neck length, and this small gain would be passed on to its offspring. (Poirier, McKee, 1999) St. Hilaire, on the other hand suggested that the change was discontinuous, large in magnitude, and occurred at the doing of offspring. However, these theories of evolution were based on explanations that offered no demonstrated mechanism. (Bowler, 1990)Darwins theory of evolution differs in that it is based on three easily corroborate observations. First, individuals within a species vary from one another in morphology, physiology, and behavior. Second, divergence is in some part heritable so that variant forms shed offspring that ... ....
