Darwinian hypothesis of biological evolution was one of the most path-breaking postulates of past couple of centuries. Its effect were felt across the disciplines. Even many theological arguments were turned on their head. It is even said that it heralded infusion of secular into the religious space. Many thinkers were so mesmerized by this hypothesis that they fancied new theories in their own respective disciplines. In fact, the circumstances that gave birth to the discipline of Sociology had a lot of bearing on Darwinian theory of Evolution. Early social thinkers were so infatuated with Darwinian thought that many linear evolutionary theories of society were put forth by as late as 1950s. Even today, we tend to believe that our ecosystems are evolving in some definite direction - some say it is progressive, while some others say it is regressive and downfall of human race will be the end result of the evolutionary process.
