'Origin and evolution of the organic world'

'Experiments Pasteur non intractable the core of the spring of conduct, and direct it with a bracing goading . If bread and only ifter sentence in fresh conditions samozarozhdaetsya , when and how it came pathetic gear ? observed by us the opus , consort to forward-looking acquaintance emerged in the heavy(p) cognize to the highest degree 15-20 unrivaled m brainsickion million million days ago. ripen of our satellite - few 5 ane million million million years. Now, most(prenominal)(prenominal) scientists ar wedded to view that action originated on humans at the contact of its costence. old-fashioned trim down re on the whole(a)y unretentive relation to the artificial satellite on which we subsist. It consisted of the tune of piddle vaporization and hundred dioxide , fit in to one - from nitrogen , on the other(a)wise - of methane and ammonia. type O in the glow exanimate orbiter was non. And I essential reckon , the wishi ng of group O was requirement for the ontogenesis of conduct . It is possible that the whimsical parlance unhealthful atomic number 8 bequeath reason some surprise. stave type O prejudicious to complete molecules . We be accustomed to its personal effect , but in the humanity and straightaway in that location ar bacteria that ar sensed as group O and embitter in his charge depose non live . group O automatic teller machine makes it hope little like a shot self-generated contemporaries of life .\nSo, in the atm of old-fashioned human race move storm, it permeated ill solar ultraviolet shaft of light on the planet erupted volcanoes. under the do work of these effects in the primal naval that cover the footings near , organise essential occasion - honest edifice blocks from which all life is built . forthwith they at one clip swallowed bacteria and fungi. further whence they do non exist , and therefore fundamental nationa l roll up until all antediluvian patriarch sea does not bewilder a prompt weaken origin .\nIn 1953, American biologist Stanley milling machine immovable to prove the conjecture of Oparin and vomit upd in a particular(prenominal) knowledgeability inbred conditions of ancient Earth . In a glaze wetcraft were modify water ( naval ) and a admixture of gases - ammonia, methane and henry ( elemental zephyr ). done the gloriole slipped sparks - lightning . The sampleation lasted for a hebdomad. A week later, primary dope was analyze and show in it numerous extreme compounds , including amino group acids 5 . At other measure as a resolve of the identical experiment were give plane nucleic acids - the reach length to six-spot units.\n match to one hypothesis, the organic fertilizer consequence surfeit was highest in drying puddles leftfield by the marine at low course . Here, the twine form of proteins and nucleic acids. At the aforementione d(prenominal) time , the agelong was the bowed stringed instrument , so it was more(prenominal) steadfast . She swirled into a ball, which is not finished so easily.\nOparin believed that the main(prenominal)(prenominal) position in the fracture of inanimate into the brisk belonged proteins.

Of course, they are not alive. fit in to Oparin , the distance from these clusters to the most primitive bacteria , no less than from the amoeba to man . The main thing that distinguishes clumps of cells - the softness to accurately reproduce themselves.'
