The main purpose of this paper is to provide an analysis of the evolutionary school of thought used in cultural anthropology, Here; I have tried to assess the significance of this school as a theoretical guideline of studying culture and society. I considered both the classical and neo-evolutionary thoughts and identified the short-comings of them. I tried to argue that despite some limitations evolutionary school can still contribute a lot to the study of culture and society. I think that the school will continue to serve our academic purpose; and as long as it does this job, it will remain functionally useful to the concerned academicians.
