WebThe concept of Darwin’s primordial soup gained credence in 1953 when American chemists Stanley Miller and Harold Urey, using a highly reduced mixture of methane, ammonia, and hydrogen, produced five amino acids. Since then, studies have questioned the experiment’s reducing atmosphere – an atmosphere without oxygen. In his original theory, Oparin considered oxygen as one of the primordial gases; thus the primordial atmosphere was an oxidising one.
