Primordial soup

In 1953, Stanley L. Miller's paper on the synthesis of amino acids under conditions that simulated primitive Earth's atmosphere was published in Science. Miller had applied an electric discharge to a mixture of CH4, NH3, H2O, and H2 (which was believed at the time to be the atmospheric composition of early Earth.) Instead of producing a random mixture of organic molecules, the surprising result was a mixture of amino acids, hydroxy acids, and urea. These compounds are so significant in the biochemistry of life, that this discovery marked the beginning of the modern study to understand the origin of life on Earth. Miller's paper was published only a few weeks after Watson and Crick reported their DNA double-helix model in Nature. Geoscientists now tend to believe in other sources for the origin of life, but Miller's experiment focussed interest on the primordial formation of amino acids
