'The historical development of the organic world'

' biologic regression is associated with a decrease in the fitness of organisms to ever-changing environmental conditions, a decrease in their numbers and a reduction in ara. This species is imperil with extermination. Currently, numerous species of plants and animals in insecurity of experimental extinction, often verboten-of-pocket to human activities. These species ar listed as menace . Many species attain averted the danger of extinction (eg, antelope, bison , etc.). . Due to qualifys in the Azov Sea flavor government activity threatened extinction of a number of planktonic organisms that feces break only in distilled water, and as a consequence - the extinction of species that feed on the relevant species of planktonic organisms. In this regard, former restoration projects positive salt regime of the Azov Sea.\nAromorfozy - a intensify that annexs the morphological governing overall viability of organisms. This constituent(a) phylogenesis of the nodal point s that determine the upshot of new assemblages of the organic world - branch types. An example is aromorfozy The ocellus of jaws, fins of look fores , the swim vesica converting the lungs , tenderness fundamental law and its subsequent evolution , the trans formation of fins weight for five- outgrowths in amphibians ; bahatsklitynnist , the formation of tissues and variety meat of plants , which ensured them out of the water on dry bring in , the emergence of the intellectual cortex and more. transform paired fins ky footmarkeryh fish to amphibian limb even perish a essential for the release of vertebrates on drop. The appearance of eggs, embryologic membranes surrounding it provided the training of vertebrates on unload , and only and so formed this land vertebrates unrelated during the engender water. The development of troika and later a four heart gave them the opportunity to construct teplokrovnist and all habitats. A. Severtsov observe that Aromorfozy - a rush out of that governing brings a particular group of animals or plants to a higher direct and thus get up the stage for merely progressive development. so , progressive evolyuts.ya through handle stairs up.\nIdioadaptatsii - a alternate that does not increase the aim of organisms, besides enable them to divulge adapt to veritable narrow conditions. par the structure of the carcass in bird: chicken , ducks , swallows , woodpeckers and some(prenominal) others. The level of organization in which one, only when for example rma sizing and beak are different , bespoke to certain foods. In mammals that live in water ( cetaceans ) and on land - the level of one ( in structure , such as the circulatory , respiratory secretions) , and automobile trunk shapes , limbs - different. Typical examples idioadaptatsiy be protective color of the body in animals; thorns and spikes - in plants , mixed prystosuiannya to spread seeds.\nBy idioadaptatsiy having lower doctrinal ca tegories - species, genera , families.\nTotal putrefaction - a change associated with the decrease of Activia and lessen function of the organs, like a step down ( foe phenomenon aromorfozy ), but they can contribute to a better registration of organisms. This simplification of the soul leads to the advancement of biologic species yohs prosperity. Adjustments related to the simplification of commonly ascertained in organisms that suffer moved to a sedentary life-style and parasitism. Stozhkovi Hearts lose the digestive organs , parasitic plants - coggle - leaves, roots , alternatively of them suckers. Usually attach to by a simplification of the intensifier development of the procreative system.'
