Natural And Human Sciences. Biological and Social Theories of Essay

Natural And Human Sciences. Biological and Social Theories of Evolution - Essay Example â€Å"A theory is an explanation or model based on observation, experimentation, and reasoning, especially one that has been tested and confirmed as a general principle helping to explain and predict natural phenomena.† (Quoted in fsteiger.com) Theories are articulated and modified for the exploration of facts and realities on the foundation of deep observation, adequate evidence and critical examination of the available information. â€Å"The vehicle of all understanding†, Turner submits, â€Å"in science is theory. Theory is a way of answering the questions.† (2006, p. 2) Hence, theories establish principles and laws and add to the knowledge of scholars, intellectuals, philosophers and the masses as well regarding multiple disciplines and issues at large. Thus, theories are equally important in natural and social sciences for the establishment of various concepts and parameters in the light of which further developments are made in some specific field of knowle dge. Though both natural and human sciences consist of theories, yet difference in both these sciences can also be witnessed in their theoretical frameworks. Pure or natural sciences concentrate upon examination of natural, organic, inorganic, physical and nonhuman laws, rules and aspects related to the earth and universe. On the other hand, social or human sciences study the existing social, cultural, religious and psychological phenomena on scientific grounds. Physics, chemistry, biology, astronomy, engineering, aeronautical science and pharmacy etc come under the definition of natural sciences, while sociology, theology, economics, history, psychology, philosophy and others are called human sciences. Though natural and human sciences appear to be entirely different from one another, yet they maintain many similarities and commonalities between them; almost same is the case with the theoretical frameworks related to both these forms of science. The similarities between the nature and scope of pure and human sciences can be analyzed as under: Biological and Social Theories of Evolution: Evolution theory enjoys a very important status in pure and social sciences. Though experiments had been made several times in past in respect of discovering the origin of humans and other living creatures, yet it was Charles Darwin who first time presented a comprehensive evolution theory on the basis of his in-depth research on fossil remains and living things including humans, fauna and flora in order to make a decisive conclusion regarding human evolution. Darwin has articulated his concept of natural selection in his world famous work On the Origin of Species, where he submits to state that it is the rule of nature that only the fittest and most suitable living creatures survive and multiply; the rest of the creatures start weakening, and eventually perish away with the passage of time. Hence, Darwin is of the opinion that those creatures and living things that have the a bility to adapt themselves according to the always changing natural and physical condition, survive and reproduce. On the other hand, the living things that either lack adaptability or sufficient strength necessary to defeat the external threats and impediments, are sure to expire, and thus lose the signs of their existence even. Darwin has submitted that the process of natural selection is the foundation of evolution of human generations. â€Å"As natural selection acts solely by the preservation of profitable modifications, each new form will tend in a fully stocked country to take the place of, and finally to exterminate its own less improved parent-form and other less favored forms, with which it comes into competition.† (1872, p.159) Darwin vehemently argues in favor of the notion natural
