Detailed explanation-1: -In 1953, Stanley Miller and Harold Urey did an experiment to test Oparin and Haldane’s ideas. They found that organic molecules could be spontaneously produced under reducing conditions thought to resemble those of early Earth.

Detailed explanation-2: -The Miller-Urey Experiment Stanley Miller and Harold Urey proved how organic life could spontaneously arise from inorganic molecules in the conditions described by Haldane and Oparin. In their experiment, Miller and Urey used a highly reducing atmosphere with a mixture of hydrogen, ammonia, methane, and water vapor.

Detailed explanation-3: -In 1953, scientists Stanley Miller and Harold Urey used their imaginations to test this hypothesis. They created a simulation experiment to see if organic molecules could arise in this way (see Figure below). They used a mixture of gases to represent Earth’s early atmosphere.

Detailed explanation-4: -In the 1950’s, biochemists Stanley Miller and Harold Urey conducted an experiment which demonstrated that several organic compounds could be formed spontaneously (through abiogenesis) by simulating the conditions of Earth’s early atmosphere.

Detailed explanation-5: -The Miller-Urey experiment In 1953 American chemists Harold C. Urey and Stanley Miller tested the Oparin-Haldane theory and successfully produced organic molecules from some of the inorganic components thought to have been present on prebiotic Earth.
