Experiments conducted by Stanley Miller and Harold Urey at the University of Chicago successfully created conditions resembling the primitive atmosphere of the earth and showed that amino acids like glycine and alanine and even more complex organic compounds can be formed in vitro when the mixture of water vapours, methane, ammonia and hydrogen gases in a closed chamber is exposed to electric discharge for few days. From this experiment Miller suggested that electric discharges produced atmosphere the effects of violent electrical storms during lightening in early atmosphere and resulted in the formation of amino acids and other complex organic compounds which are the components of living system.
