WebIn 1952, a 22-year-old student at the University of Chicago named Stanley Miller, proposed a rather simple experiment to see if simple chemical compounds could produce more complex organic compounds. He and his adviser, Harold Urey, put together a sealed system of glass flasks and tubes which contained what they thought the early Earth ... WebDec 14, 2024 · The second flask contained the “atmosphere” of four gases: water vapour, methane, ammonia, and molecular hydrogen. Electric sparks were created in the atmosphere to imitate lightning’s heat. Once the atmosphere cooled down, water “rained” down. This washed any dissolved molecules into the sea flask.

WebStanley miller and Harold urey conducted an experiment in which they recreated the primitive earth like atmosphere to explain how chemical evolution was a precursor for biological evolution. In this experiment,high electric voltage was applied on mixture of CH 3, NH 3, H 2 and water vapour by which they were able to synthesize amino acids. WebThe now-famous "Miller–Urey experiment" used a highly reduced mixture of gases—methane, ammonia and hydrogen—to form basic organic monomers, such as amino acids.
