Step-by-step solution
Based on the hypothesis proposed by Oparin and Haldane, S.L. Miller provided experimental evidence of the chemical evolution in 1953 in a laboratory set-up. S.L. Miller, an American Scientist, created similar conditions as described by Oparin and Haldane on a laboratory scale. He sealed the gases CH 4, H₂, NH 3 , and water vapor at 800 o C in a closed flask and made an arrangement of two electrodes in this flask. The electrodes created the electric discharge which provided the energy for the chemical reactions betw
