|
Explanation: 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 ac-ids was used in this experiment to explain life's origins by chemosynthesis. |
