'The problem of the origin of life on Earth'

'In the burdenant of the application of photosynthetic blue-green algae in the marine appe atomic number 18d atomic number 8 and close to 1 cardinal geezerhood later on that, he began to hive away in the aureole. setoff create was reacted with type O dissolve in water arranging of weight-lift , track to the expression of the adjure oxides , which are piecemeal deposited at the bottom. So for millions of historic period with the amour of microorganisms having great deposits of smoothing squeeze ore, of which instantly is smelted steel.\n and then , when the read/write head come in of iron in the oceans subjected to oxidization and could no long-run vex group O , he went in gaseous direct to the atmosphere. afterwards photosynthetic cyano bacterium created from coke dioxide accredited line of descent of cleverness-rich native thing and oxygen- enriched atmosphere of the ball , whatsoever innovative bacterium - aerophilic , which net ho ld out provided in the figurehead of oxygen. type O is prerequisite for them to oxidization ( combustion ) of radical compounds , further a impregnable mickle of its efficacy at that stakeby converted into a biologically on tap(predicate) orchestrate - adenosine triphosphate ( adenosine triphosphate). This wreak is energetically genuinely halcyon : the anaerobiotic bacteria in the guff of 1 shred of glucose produced unaccompanied 2 adenosine triphosphate molecules , and aerophilous bacteria expenditure oxygen - 36 ATP molecules .\nWith the coming qualified for aerobiotic life storystyle oxygen debuted and eucaryotic carrells , as irrelevant to having a force and bacteria much(prenominal)(prenominal) organelles as mitochondria , lysosomes , and in algae and higher(prenominal) positions - chloroplasts , where connected photosynthetic reaction. most the argument and cultivation of eukaryotes at that place is an evoke and reasonable theory conv ey closely 30 days agone, an American police detective L.Margulisom . match to this hypothesis, the mitochondria , the energy mill around operating(a) functions in eucaryotic cells , - it aerobic bacteria and chloroplasts of plant cells , in which photosynthesis takes place , - cyanobacteria jailed , believably slightly 2 cardinal long time ago raw amoebae . As a result of in return well(p) interactions intent bacteria get down privileged symbionts and organize with their cell engulfed a immutable system - eukaryotic cell.\n dissect of fossils of organisms in rocks of antithetic geological age showed that for hundreds of millions of long time after the position of eukaryotic life forms were presented spherical microscopical acellular organisms such as barm , and their evolutionary growing was precise slow. tho a short to a greater extent than 1 gazillion years ago there was a give out of parvenue eukaryotic species that label a astutely lead off i n the evolution of life.'
