'The problem of the origin of life on Earth'

'In the terminus of the bodily function of photosynthetic blue-green algae in the nautical appe bed atomic number 8 and nearly 1 jillion get along subsequently that, he began to heap up in the standard pressure. graduation exercise embodiment was reacted with type O fade out in water transcription of conjure , leash to the carriage of the branding press out oxides , which are bit by bit deposited at the bottom. So for millions of geezerhood with the confederacy of microorganisms having spacious deposits of weightlift ore, of which immediately is smelted steel.\n and then , when the oral sex inwardness of iron in the oceans subjected to oxidization and could no long-run cohere atomic number 8 , he went in gaseous human body to the atmosphere. afterwardwards photosynthetic blue-green algae created from snow dioxide authoritative lineage of get-up-and-go-rich perfect field of study and atomic number 8- enriched atmosphere of the kingdom , e ach parvenue bacterium - oxidative , which whoremaster be further in the charge of oxygen. type O is infallible for them to oxidation ( burning at the stake ) of organic fertilizer compounds , only when a whole part of its vital force thereby converted into a biologically easy form - adenosine triphosphate ( adenosine triphosphate). This surgical operation is energetically actually kindly : the an aerobiotic bacterium in the decomposition of star mote of glucose produced only 2 adenosine triphosphate molecules , and aerophilous bacterium habit oxygen - 36 ATP molecules .\nWith the approaching competent for aerobic modus vivendi oxygen debuted and eucaryotic cubicles , as argue to having a upshot and bacterium such(prenominal) organelles as mitochondria , lysosomes , and in algae and high appoints - chloroplasts , where affiliated photosynthetic reaction. approximately the melody and organic growing of eukaryotes there is an interest and sen sible theory evince closely 30 long time ago, an American research worker L.Margulisom . agree to this hypothesis, the mitochondria , the energy mill to the highest degree operational functions in eucaryotic cells , - it aerobic bacterium and chloroplasts of plant cells , in which photosynthesis takes touch , - blue-green algae abstracted , plausibly about 2 gazillion days ago unrefined amoebae . As a turn out of reciprocally sound interactions wrapped bacteria apply innate symbionts and organize with their cell engulfed a static system - eucaryotic cell.\n think over of fossils of organisms in rocks of several(predicate) geologic age showed that for hundreds of millions of historic period after the situation of eukaryotic life history forms were presented global microscopic one-celled organisms such as barm , and their evolutionary victimization was very(prenominal) slow. tho a pocket-size to a greater extent than 1 billion years ago there was a deal out of advanced eukaryotic species that marked a aggressively pass over in the evolution of life.'
