This Thesis is a study on the evolutionary background of aesthetic sensibility and the origin of art. Why does art persist? Why do people make art? Why do people enjoy art? What purpose does art serve? How otherwise mundane items are made into the special things we call art? After all, what is art? The traditional research to these questions does not answer adequately. Past attempts at answering these questions have taken for granted that a mysterious creative drive that seeks beauty is at the root of art. But these traditional approaches fail, on at least one count, because they are not inclusive of all art for all time and they have not a biological viewpoint. I think in principle that the application of sociobiology to man is necessary, because we are biological being primarily. The theory of evolution has significantly contributed to the conceptual unification of the sciences. And the consequence of Darwinian thinking is that the old dualism of mental/physical and biological/cultural are no longer valid. A sociobiological account of the arts must consider when and why people universally have gone to additional trouble to employ such features or elements that we call art. Ellen Dissanayake who is the author of What is Art For?(1988) explain art as 'making special'. She defines art in terms of ethological viewpoint. She writes that the manufacture or expression of what are commonly called 'the arts' is based on a universal inherited propensity in human nature to make some objects and activities special. Nancy E. Aiken who is another Darwinian propose that the emotional response to art results from reflexive reactions to certain configurations of line, shape, color, and sound, and that these reflexive emotional responses to certain visual and auditory images provide the rationale for the origin of art.
