Evolution - Essay ExampleThere is an overwhelming body of evidence which supports the surmisal that life on this planet started from a single vitality microorganism which evolved and adapted into the multitude of living creatures that inhabit the earth. Furthermore, other than the fact that there is strong evidence to conclude that the theory of evolution is salutary and valid, the author does not feel that there is similar falsifiable support for other existential theories. This story will begin by presenting an introduction into the topic of evolution, including pertinent definitions and a brief history on the issue. Then, the paper will move on to presenting necessary and sufficient evidence that backs up the authors position on evolution. This paper will also include the presentation of an objection to the authors position and a corresponding refutal of this objection. Evolution Definition and History Evolution is the change in the coordinate and behavior of organisms betwe en generations. According to Ridleys book entitled Evolution, evolutionary changes in living things do not proceed in a predictable manner instead, the details of evolution depend on the environment that a population happens to live in and the genetic variants that happen to arise by closely random processes in that population (2004). A great majority attributes the evolution theory to Charles Darwin, who, in the 1800s, was the prototypal to present a convincing explanation of how evolution works in his classic work, On the line of work of Species. However, it was the ancient Greeks who had the first known discussions about some concepts that later became part of evolutionary theory. In event a Greek scientist named Anaximander who lived during the sixth century BC said all life began in the sea. posterior on, sea creatures crawled onto dry land and over time, their bodies slowly changed, evolving into reptiles, mammals, and even people (Nardo, 2009). Evolution may be biologica l or organic, but the key point is that there is a modification in the descendants of organisms over generations. It has to be noted that the unit of evolutionary change is the population, not the individual, which is why changes are manifested in a widespread manner. Evolution Supporting Evidence Science requires the testing of explanations of the natural world against nature itself, and discarding those explanations that do not work. What distinguishes science from other ways of knowing is its reliance upon the natural world itself as the arbiter of truth. It is for this reason that the theory of evolution presents such a strong argument --- because it is deeply root in scientific foundations. Thus, its reliability has been proven time and again by a number of empirical studies, done by a number of respected personalities in the field of science. There are of import pieces of evidence that support the theory of evolution. The first is concerned with similarities between organism s that one would not expect if they had separatist origins. These similarities are found on all levels, from the molecular to the anatomical. Second, organisms can be classified in a hierarchical fashion in a nested pattern of groups within groups, as predicted by evolutionary theory. Third, biogeography plays a great role in defense of the theory of evolution. Biogeography is the study of the distribution of organisms across the world. The observation that the approximately closely related species are found close together geographically, regardless of their habitat or their
