Miller–Urey Experiment

The Miller-Urey Experiment, conducted in 1952 by chemists Stanley Miller and Harold Urey, remains a seminal milestone in the study of abiogenesis—the natural process by which life arises from non-living matter. This groundbreaking experiment sought to simulate the conditions of early Earth's atmosphere and oceans, aiming to demonstrate the plausibility of organic molecule formation under such conditions. By passing electrical discharges through a mixture of gases believed to be present on primordial Earth, Miller and Urey observed the spontaneous synthesis of various organic compounds, including amino acids, crucial building blocks of life.
