In 1952, Stanley Miller, then a graduate student at the University of Chicago, approached Harold Urey about doing an experiment to evaluate the possibility that organic compounds important for the origin of life may have been formed abiologically on the early Earth. The experiment was conducted using a custom-built glass apparatus ( Figure 1A.

The experiment. The Miller-Urey experiment (or Miller experiment) was an experiment in chemical synthesis carried out in 1952 that simulated the conditions thought at the time to be present in the atmosphere of the early, prebiotic Earth.It is seen as one of the first successful experiments demonstrating the synthesis of organic compounds from inorganic constituents in an origin of life.

Percobaan Miller-Urey. Percobaan Miller-Urey [1] (atau percobaan Urey-Miller) [2] adalah percobaan yang menyimulasikan keadaan Bumi purba dan menguji terjadinya abiogenesis. Lebih tepatnya, percobaan ini menguji hipotesis Alexander Oparin dan J. B. S. Haldane bahwa keadaan Bumi purba mendukung reaksi kimia yang dapat menyintesis senyawa.
