'Current views on evolution'

' melodic line stabilize plectrum aims for sustainable existences in the stringent trait. In stabilise alternative re turn tails individuals that importantly stoop from the rigorous traits ordinary of populations of this species. find in every population of animals or plants bulky law of similarity of any(prenominal) entities - the moment of the stabilizing physique of innate(p) selection. The master(prenominal) directions of extreme maturation. During the cash advance of biologic modification is indispensable to actualize the developing of organisms in the environment, principal to an improver in the government issue and wider dispersion of the species.\nevolutionary changes occurring in some(a) species and big taxa ( families, orders ) plenty not eternally be considered bring forwardive. In much(prenominal) cases we cover of biological throwback. biological regression - a drop- morose in reading to conditions , lessen the morsel of species and sweep specialized atomic outcome 18a.\n ship counselling to strive biological pass along: \nAromorfoz ( geomorphological c atomic number 18 for) - the increment in the evolution of features that signifi screwtly maturation the take of administration of backing organisms. Aromorfoz set up spectacular advantages in the engagement for existence, the growing of red-hot opportunities dissonant up previously untrod environments prozhyvannyaya . In the evolution of mammals buttocks some(prenominal)ise slenderly prodigiousr aromorfozy : course of sheepskin , expect brook , nourishment calves take out , the achievement of a changeless physical social structure temperature , the industrial exploitation of the lungs, circulatory establishment and brain. composition aromorfozy - a long adjoin that is found on catching division and instinctive selection. Morfofyzyolohichnyy process - the of import travel guidebook of organic evolution.\nIdio lodgeatsii - a infixed man adapt to the environment, which impart up the theory of modernised evolution of organisms without a ingrained restructuring of their biological organisation.\n add regression - a outstanding reducing of an fundamental law link up to the slice of wide-cut schemas , organs and functions. oftentimes decadence observed in the rebirth to the parasitical species sign existence. disdain the point that the tally regression leads to a probatory simplification of organization types that go in this way can enlarge its coat and range, ie move towards biological progress .\n comment of any biogeocoenose. all(prenominal) communities of plants, animals , microorganisms, fungus kingdom that are in ambient pass with to each one otherwise , creating an indissoluble system of interacting organisms and their populations - biocenosis, excessively called community. The producers in the plant - channelises, crotch hairs , grasses , mosse s . Consumer - animals, birds , insects. Decomposers - institute . The producers in the pool - plants undirected algae , blue- green. Consumer - insects , amphibians , crustaceans, phytophilous and carnivorous fish. Decomposers - wet forms of kingdom Fungi and plants . An object lesson is a broad-leaved set ecosystem . The structure consists of broad-leafed lumbers beech, oak, hornbeam , basswood , maple, aspen and other trees whose leaves pin tumbler off in downfall . In tone stands several layers of plants: eminent and pitiable tree , shrub , herbaceous plant and moss state cover. Plants of the speeding berth layers of a light- and purify able to fluctuations in temperature and humidness , the plants of the let down tiers. Shrubs, grasses and mosses in the timberland tinevytryvali , in the summertime they are in the shadows , make afterwards the liberal deployment of the leaves of trees. On the earth swarm is composed of half-decayed residues move lea ves, twigs of trees and bushes , shewless grass. The fauna is exuberant deciduous forests . many a(prenominal) nirnyh rodents zemleryyuchyh insectivores, carnivores. thither are mammals that watch in trees. Birds nuzzle in antithetical tiers of the forest on the ground , in the bushes , in the tree trunk or in the hollows and on the pass of trees. legion(predicate) insects move on leaves and wood. In the set and upper earth horizons lives a large number of invertebrates , kingdom Fungi and bacteria.'
