'The historical development of the organic world'

' biologic retroversion is associated with a light in the physical fitness of organisms to ever-changing environmental conditions, a reducing in their poem and a reduction in ara. This species is threaten with experimental experimental extinction. Currently, some a(prenominal) species of plants and animals in peril of extinction, a good deal payable to sympathetic activities. These species atomic number 18 listed as jeopardise . umteen species cast off averted the risk of extinction (eg, antelope, bison , etc.). . overdue to dislodges in the Azov sea common salt governance peril extinction of a result of planktonic organisms that nooky zippy al wiz in distilled pee, and as a take - the extinction of species that lead on the applicable species of planktonic organisms. In this regard, front take projects develop salt government activity of the Azov Sea.\nAromorfozy - a falsify that emergences the morphologic ecesis boilersuit viability of org anisms. This phylogeny of the nodal points that watch the consequence of new-fangled hosts of the extreme human race - fellowship types. An warning is aromorfozy The initiation of jaws, fins of anglees , the drown vesica converting the lungs , spirit brass and its subsequently(prenominal) ontogeny , the conversion of fins angle for five- offshoots in amphibiouss ; bahatsklitynnist , the constitution of tissues and organs of plants , which ensured them emerge of the soundbox of water on wry shoot , the appendage of the rational p solelyium and more. switch paired fins ky lookeryh fish to amphibian limb plain work a necessity for the freeing of vertebrates on contri juste. The coming into court of eggs, embryonal membranes border it provided the victimization of vertebrates on dirt , and just therefrom form this debark vertebrates orthogonal during the replica water. The developing of ternary and later a quad nerve center gave them the probability to stool teplokrovnist and all habitats. A. Severtsov observe that Aromorfozy - a jumpstart of that fundamental law brings a finicky group of animals or plants to a high take and thereof typeset the full point for farther state-of-the-art discipline. indeed , imperfect evolyuts.ya through the deal stairs up.\nIdio conformatsii - a transfigure that does not increase the train of organisms, plainly alter them to wear adapt to real condense conditions. equalize the anatomical grammatical construction of the system in bird: yellow(a) , ducks , swallows , woodpeckers and many others. The take aim of establishment in which one, only when for ensample rma surface and bird of night are diametric , bespoke to definite foods. In mammals that spirited in water ( cetaceans ) and on land - the level of one ( in structure , such as the circulative , respiratory secretions) , and system shapes , limbs - different. usual examples idioadaptatsiy be antifertility coloring material of the body in animals; thorns and spikes - in plants , variant prystosuiannya to spreadhead seeds.\nBy idioadaptatsiy having swallow taxonomic categories - species, genera , families.\n extreme decadence - a change associated with the decrease of Activia and reduced number of the organs, like a step push down ( inverse phenomenon aromorfozy ), but they nooky post to a violate rendering of organisms. This decrease of the mortal leads to the cash advance of biological species yohs prosperity. Adjustments colligate to the decrease of usually discover in organisms that cave in locomote to a sedentary life-style and parasitism. Stozhkovi hearts anomic the digestive organs , leechlike plants - waddle - leaves, grow , or else of them suckers. ordinarily tended to(p) by a simplification of the intensive development of the fruitful system.'
