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 ...
The Miller–Urey experiment sought to recreate the early Earth atmosphere within a laboratory setting to determine the chemical processes that ultimately led to life on Earth. [1] The basis of this experiment was leveraged on Oparin's hypothesis, which assumed that some organic matter could be created from inorganic material given a reduction ...

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.
Several decades later, the Miller-Urey experiment provided the first empirical basis for these ideas. Inspired by Oparin's theory, University of Chicago chemists Stanley Miller and Harold Urey applied an electric discharge analogous to a lightning strike to a seawater-like system of water and reduced gasses meant to simulate the prebiotic ...
Origin of life – hierarchy of life – Miller–Urey experiment; Macroevolution: adaptive radiation – convergent evolution – extinction – mass extinction – fossil – taphonomy – geologic time – plate tectonics – continental drift – vicariance – Gondwana – Pangaea – endosymbiosis
Urey, along with his student Stanley Miller, may be best remembered for the renowned Miller-Urey experiment, which shows that a mixture of ammonia, methane and hydrogen, when exposed to ultraviolet radiation and water, can interact to form amino acids, the "building blocks" of terrestrial life.
In 1953, Stanley Miller attempted an experiment to investigate whether chemical self-organization could have been possible on pre-historic Earth. The Miller–Urey experiment [ 11 ] introduced heat (to provide reflux) and electrical energy (sparks, to simulate lightning ) into a mixture of several simple components that would be present in a ...
