The Miller-Urey experiment In the 1930s, Oparin and Haldane independently suggested that ultraviolet radiation from the sun or lightning discharges caused the molecules of the primordial atmosphere to react to form simple organic (carbon-containing) compounds. He based his calculations on the (then) widely held view that the early atmosphere was reducing, and concluded that the main constituents were methane (CH 4), ammonia (NH 3), hydrogen (H 2), and water (H 2 O). This apparatus configuration, now referred to as the classic apparatus, was the one most extensively used in the original experiments, and is … STANLEY MILLER The apparatus Miller and Urey designed was meant to simulate the ocean-atmosphere system on primitive Earth. In the 1950's, biochemists Stanley Miller and Harold Urey, conducted an experiment which demonstrated that several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere.. 011 - The Origin of Life - Scientific Evidence Paul Andersen discusses scientific evidence of the origin of life on our planet. They designed an apparatus which held a mix of gases similar to those found in Earth's early atmosphere over a pool of water, representing Earth's early ocean. the first step of life and the changing of inorganic molecules to complex organic molecules ,explanation of oparin-haldane hypothesis and urey miller experiment – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 7f3b62-ZWVkO
