Experimentos de Miller-Urey: Em 1953, Stanley Miller e Harold Urey realizaram um experimento para simular as condições da Terra primitiva e testar a hipótese de Oparin. Eles criaram uma mistura de gases que acreditavam que estavam presentes na atmosfera da Terra primitiva, como … L'expérience de Miller (dite encore de Miller-Urey), destinée à mettre en évidence une éventuelle origine chimique de l'apparition de la vie sur Terre, consista à simuler les conditions supposées régner originellement après la formation de la croûte terrestre. Elle avait pour objectif de mettre à l'épreuve l'hypothèse d'Oparin et de Haldane, selon laquelle les conditions existant alors sur Terre auraient favorisé les réactions chimiques susceptibles de faire apparaître des composés organiq…
