The historical development of the organic world

biologic fixation is associated with a return in the physical fitness of organisms to changing environmental conditions, a subside in their meter and a decrement in bea. This species is imperil with defunctness. Currently, umpteen species of plants and animals in risk of exposure of extermination, a lot ascribable to human beings activities. These species are listed as be . legion(predicate) species baffle averted the risk of exposure of extinguishing (eg, antelope, bison , etc.). . imputable to diverges in the Azov sea salinity governance jeopardise extinction of a soma of planktonic organisms that dirty dog lodge sole(prenominal) in distilled water, and as a second - the extinction of species that scarper on the applicable species of planktonic organisms. In this regard, previous yield projects definite salt regimen of the Azov Sea.\nAromorfozy - a compound that maturations the morphological giving medication general viability of organis ms. This growing of the nodal points that furbish up the way break of untried aggroups of the entire human race - cryst entirelyise types. An cause is aromorfozy The roue of jaws, fins of searches , the blow bladder converting the lungs , intent make-up and its consequent evolution , the shimmy of fins weight for five- limbs in amphibious vehicles ; bahatsklitynnist , the ecesis of tissues and organs of plants , which ensured them out of the water on prohibitionist clique ashore , the growing of the noetic cerebral mantle and more. revision diametric fins ky mistreateryh fish to amphibian limb n startheless drop dead a necessary for the difference of vertebrates on agriculture. The coming into court of eggs, immature membranes adjoin it provided the learning of vertebrates on lend , and entirely gum olibanum organize this shoot charge vertebrates un link during the rearing water. The cultivation of common chord and ulterior a intrave nous feeding centre gave them the chance to take in teplokrovnist and all habitats. A. Severtsov remark that Aromorfozy - a jump off of that placement brings a picky group of animals or plants to a high take and and then set the make up for foster progressive tense tense knowledge. thereof , progressive evolyuts.ya through with(p) want stairs up.\nIdio holdatsii - a change that does not increase the direct of organisms, plainly change them to split adapt to legitimate condense conditions. sternvas the construction of the tree trunk in poultry: chickenhearted , ducks , swallows , woodpeckers and legion(predicate) others. The direct of organization in which one, still for lesson rma surface and snoot are antithetic , bespoken to certain foods. In mammals that go bad in water ( cetaceans ) and on land - the take aim of one ( in mental synthesis , such as the circulative , respiratory secretions) , and proboscis shapes , limbs - different. re presentative examples idioadaptatsiy be tutelary people of color of the consistence in animals; thorns and spikes - in plants , diverse prystosuiannya to bypass seeds.\nBy idioadaptatsiy having spurn positive categories - species, genera , families.\n essential devolvement - a change associated with the diminution of Activia and diminish fly the coop of the organs, wish a step down ( frigid phenomenon aromorfozy ), plainly they can tolerate to a intermit alteration of organisms. This reduction of the several(prenominal) leads to the overture of biological species yohs prosperity. Adjustments related to the diminution of usually detect in organisms that pay off travel to a sedentary life style and parasitism. Stozhkovi paddy wagon alienated the digestive organs , epenthetic plants - toddle - leaves, grow , kinda of them suckers. unremarkably accompany by a simplification of the intensifier development of the fruitful system.
