(S.L. Miller) created electric discharge in a closed flask, containing CH4, H2 , NH3 , and water vapour, at 800°C in a laboratory
He observed formation of organic compound / amino acids
He proved the theory of abiogenesis / the first form of life arose slowly through evolutionary process from non-living molecules / first form of life could have come from pre-existing non-living organic molecules & formation of life was preceded by chemical evolution / formation of of diverse organic molecules from inorganic constituents
