About what might be the process that led to the formation of life from inert elements, it is still controversy and cornerstone for the fundamental understanding of the primordial origin of organisms. Once "Louis Pasteur" try the non-viability of the approach of "spontaneous generation" admitted in his day by "Aristotle" and widely extended in the middle ages, were born alternative theories which gave rise to new expectations environment to the possible emergence of organic molecules from inorganic basic substances. This was the case with "Stanley Miller and Urey" which projected the beginning of "abiogenesis" through the "primordial soup" call by which inert elements exposed to extreme conditions (lightning, impact of meteorites and volcanic activity, earthquakes, etc.) that loaded them power could lead to the origin of elements that participate in life. Molecules organic that is were transforming in substances complex until led to the possibility of organisms capable of play is. These first beings are those who would take care of transforming large amounts of carbon dioxide into oxygen.
"He emerge from life. "Microorganisms elementary starting from which is formed organisms more complex in an outbreak of reproduction, that certainly could be a made casual that ended by having a huge success."
