He also maintains that the different species have gradually evolved through a certain natural process, which he called "Natural Selection". His above assumptions about the evolution of the universe lead to some problems of thinking the universe as wholly co-operative system that is the morality of nature. In this article, I explain the fundamental views of Darwin`s theory of evolution from the very beginning. Then I try to show that competition as well as co-operation is the basic role of nature. A short conclusion end the paper that enlighten importance of co-operation, correcting the tendency of our social system though there is competition as a way of achieving goal. Keywords:
