Several hypotheses were formulated to explain the emergence of life on our planet, they believed that this process occurred not only by crossing each other, but also, from a raw material. This idea was proposed by Aristotle over 2000 years. Aristotle - Emergence of life would be from active ingredients contained in certain foods, which when ingested could be activated. (Abiogenesis). tupperware brands Francesco Redi - life originates only from other existing, provided that he finds a favorable environment for their development (Biogenesis). In this sense, there have been several cases in which the heterotrophic is more accepted despite agreeing to abiogenesis towards being sourced from raw material, but then admits a slower evolution and which would require prefabricated organic matter to ensure its survival . From 1954 the scientists Miller, tupperware brands Fox and Calvin reproduced through experiments tupperware brands the likely conditions of life in the early atmosphere, in which demonstrated the possibility of forming organic compounds (amino tupperware brands acids, proteins and carbohydrates) that that period would be dragged by rainwater primitive to the sea water and be deposited there and mixed with other organic and inorganic compounds that were up to its time comprising, providing the physical basis on which to form the life.
whose experience has become famous. This experiment was designed to test the possibility of forming Abiotic monomers under the conditions tupperware brands of Oparin's tupperware brands theory. In 1953, Miller introduced in a flask a mixture of methane, tupperware brands ammonia, hydrogen and water. This mixture was constantly bombarded by lightning than 60,000 V and kept circulating in the machine by the water vapor created by boiling water. This procedure was continued for one week, after which samples are collected are analyzed by chromatography. The analysis showed that the yellowish liquid which had formed containing many kinds of amino acids (alanine, aspartic acid and glutamate) and simple organic acids (formic, acetic, propionic, lactic and succinic acids) useful in living beings.
