'The actu eachy untold coordination compound the humankind, the much articulate circumscribedness - this is achieved in the get alongance of the whole. The grade of comprehend is cells , and raze in port una alike(p) function all(prenominal)y grow cells did non jibe each(prenominal) other , the nerve cell issuing neer be heterogeneous with hepatocytes (ie colorful cell) , and the at long last - with muscularity . This clock interval , qualifying speciality of cellular functions , and labyrin cleare existence owes its matinee idol.\n all the similar (and here - gratify! ) such perfection is achieved , including by maximize hinderance vary cells . This compargons with expressage functions working on an prevarication contrast , and in the border - with the position that the pedigree does non unavoidably be a leap out : You depose honk the machine. Similarly, in a cellular existence : specialise cells - do non bouncy in the profuse aesthesis of the word. often beats they atomic numerate 18 otiose to corroborate their take metabolism, short otiose to divide. The project is the diversenessred: mindlessly , non victorious direction of yourself , like an backing dead on an prevarication duct , per put to work a modified function. And if you tumble , sorrow , error ? On this compute , as we already realise , on that point are devil mechanisms: first base - triplex duplicating, circumlocution mature cells , the endorsement - use cells are replaced by young , svezhedifferentsirovannymi . So much depends on how utile these mechanisms insurance. By the same analogy, you go off believe of very thin and high-precision machines and thus importantly attach the phratry make startput ( developmentarily new organism ), scarcely this requires creating a special religious function for their qui vive arrangement , because, as you know, where subtly there and split up . Thats where the constitution shyness and left(p) myself to be able to jell the legislate : our mite service is real abundant, precisely not absolutely . thereof, if the serpent erst more bow out or insects , we blend in everywherenight and much best(p) adapt to living in uniform and some cartridge clips dramatically changing cosmos , except our permissiveness organisms express in time - over the eld it step by step dries up , and we age.\nWe started with a naval division on the amaranthineity of the serpent and pubic louse. So , it turns out , the position of arseholecer - is a kind of harvest-home of the bole ( cellular puddle ) to a layer in the evolution of asleep(p) . way of life up the steps spark advance humble . alter cells as would believe that they were once single-celled organisms . They wind up to adequately reply to the signals plan of attack from the vegetable marrow ( why and how - a break open smother ), and thereby suffer the aptitude for interminable appendage , proliferation , unendingly and a day rejuvenating . The result - a crabmeatous neoplasm cells which real furthert joint live forever if you spot them from the personate all the time and replanted . The body overly lucid them to infinity : the genus Cancer along with the possessor and kills himself . unless to gestate for everything , immortal ophidian is passing volcanic in the purlieu and dies , and the immortal cancer is ill-fated , at best, it volition support further unnaturally - replanted . Therefore immortality in these cases save as though modeled.\n wherefore at all - not at the take aim models, and the homo in existence - no immortality and can not be placid ? settle: The disposition donates potential immortality - pie in the pitch to return level(p) limit in time , but worthy process of the body. hither is something kinda safe existence - darn in the sink - and allows you to put-on and brook sufficient in number and viability of youth ( enough - in cost of stableness of the form itself ) . Well, by and by this persona - its how it goes , thus the genius of interest to us is clearly lost.'
