He demonstrated that life arises only from pre-existing life.Oparin and Haldane proposed the theory of chemical evolution. According to them,the first form of life originated from pre-existing non-living organic molecules (like $RNA$,proteins,etc.) through a series of chemical reactions in the primitive atmosphere.
