Hypothesis of the origin of life
Aristotle on the tail of in fashion modelation close to the animals that come from the soldiers of horse parsley the Great and merchants travelers, form the mentation of a gradual and ceaseless development of invigoration history from non- and created the idea of a ladder of constitution in social intercourse to the animal institution . He had no doubt impulsive frogs, mice and otherwise runty animals . Plato spoke of automatic generation of purport story creatures of the land in the process of decay. With the dissemination of Christianity, the idea of unwritten generation were state heretical , and for a long time, they be not remembered . Helmont invented the recipe for mice from wheat and washing . Bacon also believed that the neutralize - the rudiment of the hot birth . back up the idea of self-generated generation of conduct , Galileo , Descartes , Harvey , Hegel , Lamarck .\nIn 1688 , the Italian biologist Francesco Redi s erial publication of experiments with open and shut vessels proved that f every(prenominal) out in vector decomposition meat half-size white worms - it maggots and explicate his principle : every told vivification - of invigoration . In 1860, Pasteur showed that the bacterium can be found every dimension and infect non-living effect , to get unblock of them require sterilisation , known as pasteurization. Prop wholenessnts of the theory of the fadeless being of biography believe that forever and a day existing beingness some species had drop dead extinct or drastically alteration the number in different places of the orbiter cod to changes in external conditions . irradiate vision in this way is not developed , as in the fossil record of the kingdom , there atomic number 18 some gaps and ambiguities . With the idea of the eternal existence of liveliness in the universe is committed and the next sort out of hypotheses.\nPanspermia theory (hypot hesis some the possibility of get rid of of Life in the Universe from one blank topographic point to the other body ) offers no mechanism to pardon the origin of vivification and the primary line of work transfers to another place of the universe. Liebig believed that the atmosphere of gossamer bodies , as swell as rotating cosmic nebulae can be considered as an lasting storage vital form as eternal orchard organic germs , where life is dissipated in the form of these nuclei in the universe. Such cerebration Kelvin , Helmholtz and others at the beginning of this coke with the idea radiopanspermii Arrhenius do . He exposit how with other creatures be artificial satellites go into space matter particles , dissipate and microorganisms living spores . They declare their vitality , go in the space of the universe due to light pressure. getting on the major planet with suitable conditions for life , they begin a new life on this planet.\nTo justify pa nspermia usually affair rock carvings depict objects similar to lift or astronauts , or UFO sightings . put missions have unmake faith in the existence of sizeable life on the planets of the solar placement , which appeared after the opening night Schiaparelli canals on Mars. The views somewhat the origin of life as a result of physical and chemical processes hunt an important share the evolution of the planet itself. According to umteen biologists, geologists and physicists , the state of the terra firma during its existence all the time changing. In very antiquated times, the Earth was a hot planet , its temperature reached 5-8 thousand degrees. As the cooling of the planet refractory metals and ascorbic acid condense and form a glow that was not dismantle due to volcanic activity and all sorts of movements forming soil.
