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 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. [3] This provided direct experimental support for the second point of the "soup" theory, and it is one of the remaining two points of the theory that much of the debate now centers.
While a large amount of key prebiotic compounds, such as methane, are found at vents, they are in far lower concentrations than estimates of a Miller-Urey Experiment environment. In the case of methane, the production rate at vents is around 2-4 orders of magnitude lower than predicted amounts in a Miller-Urey Experiment surface atmosphere ...

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.
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.
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 ...
