Question

How did S.L Miller experiment supported Oparin and Haldane's proposal?

Answer 1

Oparin and Haldane proposed a Oparin Haldane hypothesis. It proposed the chemical evolution of life. According to this hypothesis, the first form of life came from pre-existing non-organic molecules. S.L. Miller supported their proposa. He created Earth's reducing atmosphere during early days of development. He created electric discharge in a closed flask containing methane, hydrogen, ammonia and water vapour at 800${}^0$C. This resulted is the formation of amino acids. Hence, this experiment supported that the chemical evolution of organic molecules occurred from the inorganic substances.
