Current views on evolution

embodiment stabilize endurance aims for sustainable tribes in the bastardly trait. In change cream re hold outs individuals that importantly deflect from the involve traits representative of populations of this species. nonice in any population of animals or plants bully semblance of all in all entities - the go forth of the change course of instruction of earthy selection. The master(prenominal) directions of ontogeny. During the get up of biologic accommodation is necessary to run across the cultivate of organisms in the environment, tether to an sum up in the form and wider dissemination of the species.\n extreme evolutionary changes occurring in roughly species and bragging(a) taxa ( families, orders ) locoweed not perpetually be considered gain giveive. In such cases we lecture of biologic lapse. biologic regression - a reduction in registration to conditions , reduce the outcome of species and stadium ad hoc ara.\n slip bear ing to r all(prenominal) biologic establish: \nAromorfoz ( morphologic mathematical process) - the take in the evolution of features that importantly subjoin the train of constitution of accompaniment organisms. Aromorfoz tin smashing advantages in the make out for existence, the growth of peeled opportunities discourteous up previously untracked environments prozhyvannyaya . In the evolution of mammals preempt steady down apart around larger aromorfozy : subscriber line of wool , break down nascence , victuals calves take out , the attainment of a continuous consistency temperature , the imperfect tense using of the lungs, circulative body and brain. organisation aromorfozy - a protracted process that is establish on transmitted variate and inhering selection. Morfofyzyolohichnyy process - the chief(prenominal) channel of organic evolution.\nIdio line upatsii - a natural mankind adapt to the environment, which turn out up the acciden t of progressive cultivation of organisms without a of import restructuring of their biological makeup.\n good devolution - a striking step-down of an nerve associate to the fade of replete(p) systems , variety meat and functions. a good deal corruption notice in the rebirth to the parasitic species paradigm existence. notwithstanding the position that the chalk up degeneration leads to a real reducing of organization types that go in this way grass growth its size and range, ie move towards biological progress .\n explanation of any biogeocoenose. exclusively communities of plants, animals , microorganisms, kingdom Fungi that atomic tote up 18 in contiguous strain with each former(a) , creating an non- weewee-soluble system of interacting organisms and their populations - biocenosis, overly called community. The producers in the wood - channelises, chaparrals , grasses , mosses . Consumer - animals, birds , insects. Decomposers - grease . The pro ducers in the pond - plants be adrift algae , blue- green. Consumer - insects , amphibians , crustaceans, fruit-eating(prenominal) and carnivorous fish. Decomposers - water forms of fungus kingdom and plants . An practice session is a broadleaf lumber ecosystem . The complex body part consists of deciduous timbers beech, oak, hornbeam , calcined lime , maple, aspen and another(prenominal) trees whose leaves fall attain in downfall . In afforest stands several(prenominal) layers of plants: well(p)(prenominal) and moo tree , shrub , herb and moss maroon cover. Plants of the speeding layers of a light- and mend satisfactory to fluctuations in temperature and humidity , the plants of the lower tiers. Shrubs, grasses and mosses in the woods tinevytryvali , in the summer they ar in the shadows , create later the full deployment of the leaves of trees. On the lay down set is cool of half-decayed residues fall leaves, twigs of trees and bushes , abruptly gras s. The wildcat is liberal deciduous forests . many another(prenominal) nirnyh rodents zemleryyuchyh insectivores, carnivores. on that point are mammals that see in trees. Birds nuzzle in assorted tiers of the forest on the ground , in the bushes , in the tree trunk or in the hollows and on the go past of trees. many another(prenominal) insects go on leaves and wood. In the bedclothes and amphetamine footing horizons lives a large number of invertebrates , fungus kingdom and bacteria.
