The Miller–Urey experiment of 1952 simulated the conditions thought at the time to be present on the early Earth, and tested the chemical origin of life under those conditions in a laboratory. The experiment demonstrated how amino acids could be generated in a lab environment from simple compounds subjected to electrical discharges in the early Earth’s atmosphere. The spontaneous creation of amino acids was used in this experiment to explain life’s origins by chemosynthesis.
