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 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 atmosphere. [1] Using a mixture of water, methane , ammonia , and hydrogen in glass tubes, Miller and Urey replicated the effects of lightning on the mixture using electrodes . [ 1 ]

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
Hershey–Chase experiment (by Alfred Hershey and Martha Chase) uses bacteriophage to prove that DNA is the hereditary material (1952). Meselson–Stahl experiment proves that DNA replication is semiconservative (1958). Crick, Brenner et al. experiment using frameshift mutations to support the triplet nature of the genetic code (1961).
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 ...
