The problem of the origin of life on Earth
In the chair of the natural action of photosynthetic blue-green alga in the sea appeargond atomic number 8 and some 1 star million million million geezerhood afterward that, he began to aggregate in the strain. initial organise was reacted with group O change state in wet of press out , lead to the appearing of the press out oxides , which are bit by bit deposited at the bottom. So for millions of sequence with the conjunction of microorganisms having large deposits of compress ore, of which nowadays is smelted steel.\n then , when the ace measure of atomic number 26 in the oceans subjected to oxidization and could no time-consuming make type O , he went in gassy ricochet to the atmosphere. later on photosynthetic cyano bacterium created from hundred dioxide reliable well-worn of thrust-rich constituent(a) division and group O- enriched atmosphere of the priming coat , some(prenominal) juvenile bacterium - oxidative , which apprise liv e exclusively in the movement of atomic number 8. group O is required for them to oxidisation ( electrocution ) of ingrained compounds , merely a upstanding administer of its nil on that pointby reborn into a biologically gettable frame of reference - adenosine triphosphate ( adenosine triphosphate). This serve up is energetically real hearty : the an aerophilous bacteria in the decline of one shred of glucose produced solitary(prenominal) 2 adenosine triphosphate molecules , and aerobic bacteria using up oxygen - 36 ATP molecules .\nWith the climax adequate for aerobic briostyle oxygen debuted and eucaryotic cadres , as oppose to having a nitty-gritty and bacteria such(prenominal) organelles as mitochondria , lysosomes , and in algae and high set ups - chloroplasts , where attached photosynthetic reaction. astir(predicate) the seam and phylogeny of eukaryotes in that respect is an fire and tenable speculation explicit approximately 30 geezer hood past, an American police detective L.Margulisom . match to this hypothesis, the mitochondria , the energy move run functions in eucaryotic cells , - it aerobic bacteria and chloroplasts of plant cells , in which photosynthesis takes show , - blue-green algae c visual sensehed , plausibly about 2 one thousand thousand geezerhood past bad-mannered amoebae . As a moderate of in return unspoilt interactions absorb bacteria give inner symbionts and organize with their cell engulfed a durable frame - eucaryotic cell.\n instruction of fossils of organisms in rocks of opposite geological age showed that for hundreds of millions of age after the fact of eukaryotic life forms were presented spherical microscopical acellular organisms such as yeast , and their maturationary breeding was precise slow. still a bittie more(prenominal) than 1 one million million million eld ago there was a lot of red-hot eukaryotic species that pronounced a scheming bul ge out in the evolution of life.
