Stanley Miller in 1999, posed with an apparatus like that used in the original experiment. At the time of the Miller–Urey experiment, Harold Urey was a Professor of Chemistry at the University of Chicago who had a well-renowned career, including receiving the Nobel Prize in Chemistry in 1934 for his isolation of deuterium [21] and leading ...
In 1952 he performed the Miller–Urey experiment, which showed that complex organic molecules could be synthesised from inorganic precursors. The experiment was widely reported, and provided evidence for the idea that the chemical evolution of the early Earth had caused the natural synthesis of organic compounds from inanimate inorganic molecules.
Sidney Fox based his experiments off of the information found in the Miller–Urey experiment. The Miller–Urey experiment was performed by scientist Stanley Miller under the guidance of Harold Urey in the early 1950s. [7] In the Miller–Urey experiment, water was boiled in a flask with the gases hydrogen, ammonia, and methane.
The Miller–Urey experiment used a highly reducing mixture of gases—methane, ammonia, and hydrogen, as well as water vapor—to form simple organic monomers such as amino acids. [37] The mixture of gases was cycled through an apparatus that delivered electrical sparks to the mixture.

1953 – Stanley L. Miller & Harold C. Urey: Miller–Urey experiment demonstrates that organic compounds can arise spontaneously from inorganic ones. 1955 – Clyde L. Cowan and Frederick Reines confirm the existence of the neutrino in the neutrino experiment. 1958 – Meselson–Stahl experiment proves that DNA replication is semiconservative.
[3] [4] This was achieved during the period 1959–1962 and stands, together with the Miller-Urey experiment, as one of the fundamental results of prebiotic chemistry. It opened up a research area eventually leading to the complete synthesis of other components of nucleic acids. [citation needed]
The hypothesis gained some empirical support in 1953 with the classic Miller–Urey experiment. Since then, the primordial soup theory (Oparin–Haldane hypothesis) has become the foundation in the study of abiogenesis. [88] [89] [90]
