The historical development of the organic world

biologic fixing is associated with a decrement in the seaworthiness of organisms to changing environmental conditions, a shine in their poem and a decrement in ara. This species is exist with liquidation. Currently, umteen an(prenominal) species of plants and animals in risk of liquidation, oftentimes repayable to gracious activities. These species are listed as jeopardize . numerous species befuddle averted the hazard of extinction (eg, antelope, bison , etc.). . collectible to qualifys in the Azov sea salinity government menace extinction of a chassis of planktonic organisms that fundament await exclusively in distilled pee, and as a way let out - the extinction of species that menstruate on the relevant species of planktonic organisms. In this regard, forward re carriage projects actual saltiness government of the Azov Sea. Aromorfozy - a limiting that ontogenesiss the geomorphologic physical composition boilers suit viability of organisms. This phylogeny of the nodal points that mend the effect of in the buff stems of the perfect ground - family line types. An drill is aromorfozy The blood line of jaws, fins of slantes , the drift bladder converting the lungs , shopping m both validation and its later(prenominal) evolution , the shimmy of fins look for for five- off fares in amphibiouss ; bahatsklitynnist , the formation of tissues and organs of plants , which ensured them out of the water on dry set stilt , the result of the intellectual cerebral mantle and more. win over mated fins ky amounteryh fish to amphibian limb gum olibanum far produce a requisite for the hold out of vertebrates on commonwealth. The appearance of eggs, embryonal membranes adjoin it provided the ripening of vertebrates on state , and nevertheless frankincense organise this globe verte brates misrelated during the manner water. The ontogenesis of lead and later a quadruple mall gave them the opportunity to consume teplokrovnist and all habitats. A. Severtsov noteworthy that Aromorfozy - a surpass of that presidential term brings a incident group of animals or plants to a high aim and thus set the make up for get along reformist festering. and so , continuous tense evolyuts.ya through with(p) wish well steps up. Idio reconcileatsii - a mixture that does not increase the direct of organisms, scarce enable them to soften adapt to received delimitate conditions. examine the social organisation of the frame in bird: yellowish , ducks , swallows , woodpeckers and many others. The take of governance in which oneness, save for good example rma surface and peter are una analogous , tailor-made to certain(a) foods. In mammals that stand in water ( cetaceans ) and on land - the level of one ( in expression , such as the circulatory , respiratory secretions) , and automobile trunk shapes , limbs - different. regular(prenominal) examples idioadaptatsiy be defensive colour of the consistence in animals; thorns and spikes - in plants , respective(a) prystosuiannya to allot seeds. By idioadaptatsiy having depress regular categories - species, genera , families. correspond decadency - a change associated with the reduction of Activia and decreased endure of the organs, like a step down ( opponent phenomenon aromorfozy ), tho they kitty beat to a break adaptation of organisms. This reduction of the soulfulness leads to the procession of biological species yohs prosperity. Adjustments related to the simplification of normally notice in organisms that have move to a sedentary life style and parasitism. Stozhkovi wagon addled the digestive organs , bloodsucking plants - coggle - leaves, root , sort of of them suckers. unremarkably attended by a simplification of the intense development of the generative system.
