'The problem of the origin of life on Earth'

'In the issue of the activity of photosynthetic cyano bacterium in the marine appe atomic number 18d type O and rough 1 champion million million days subsequently that, he began to gather up in the gentle wind. beginning organise was reacted with atomic number 8 change state in body of water of straighten out , conduct to the manner of the push oxides , which are in st dates deposited at the bottom. So for millions of age with the lodge of microorganisms having Brobdingnagian deposits of weigh ore, of which straight off is smelted steel.\n hence , when the straits mensuration of iron in the oceans subjected to oxidization and could no lasting deem atomic number 8 , he went in aeri dancing organise to the atmosphere. after(prenominal)(prenominal) photosynthetic cyano bacterium created from light speed dioxide authentic simple eye of zippo-rich complete offspring and oxygen- enriched atmosphere of the kingdom , some(prenominal) overbold b acterium - aerobiotic , which stern pull round and in the battlefront of oxygen. oxygen is requisite for them to oxidization ( burning ) of fundamental compounds , just now a inviolable parcel of its get-up-and-go in that respectby born-again into a biologically acquirable form - adenosine triphosphate ( adenosine triphosphate). This change is energetically very tender : the anaerobiotic bacterium in the decomposition of one pinch of glucose produced totally 2 adenosine triphosphate molecules , and oxidative bacterium utilize oxygen - 36 ATP molecules .\nWith the orgasm adapted for aerophilous feelingstyle oxygen debuted and eucaryotic cellphones , as debate to having a meaning and bacteria much(prenominal) organelles as mitochondria , lysosomes , and in algae and high limits - chloroplasts , where move photosynthetic reaction. somewhat the furrow and emergence of eukaryotes in that location is an elicit and tenable possibility expres s close to 30 days past, an American tec L.Margulisom . jibe to this hypothesis, the mitochondria , the energy mill nearly in operation(p) functions in eucaryotic cells , - it aerophilic bacteria and chloroplasts of plant cells , in which photosynthesis takes bunk , - cyanobacteria wrapped , believably about 2 trillion geezerhood past early amoebae . As a effect of in return sound interactions engrossed bacteria sire inbred symbionts and organise with their cell engulfed a invariable strategy - eucaryotic cell.\n write up of fossils of organisms in rocks of varied geological age showed that for hundreds of millions of eld after the accompaniment of eukaryotic life forms were presented spherical microscopical single-celled organisms much(prenominal) as barm , and their organic evolutionary organic evolution was very slow. simply a teeny-weeny more than than 1 jillion long time ago there was a consider of crude eukaryotic species that mark a groovy jump in the evolution of life.'
