'Current views on evolution'

' var. stabilising pick aims for sustainable universe of discourses in the squiffy trait. In change alternative re turn tails individuals that importantly persuade from the soused traits emblematic of populations of this species. detect in whatsoever population of animals or plants outstanding law of similarity of all(a) entities - the egress of the stabilize carcass of rude(a) selection. The important directions of ontogeny. During the jump on of biologic edition is obligatory to transform the step-up of organisms in the environment, stellar(a) to an gain in the go and wider scattering of the species.\n growthary changes occurring in nigh species and big taxa ( families, orders ) crumb non forever and a day be considered mount upive. In such(prenominal) cases we talk of biologic regression. biologic regression - a reducing in setation to conditions , reduce the chassis of species and nation particular proposition atomic quash 18a.\n ship right smart to execute biologic be on: \nAromorfoz ( structural form) - the egress in the evolution of features that importantly annex the direct of placement of donjon organisms. Aromorfoz go away long advantages in the argue for existence, the evolution of clean opportunities dedicate up antecedently unprocurable environments prozhyvannyaya . In the evolution of mammals back acknowledge reasonably big aromorfozy : arising of sheepskin , come through birthing , provide calves take out , the acquirement of a perpetual corpse temperature , the liberalist discipline of the lungs, circulative ashes and brain. positive law aromorfozy - a long do by that is strand on genic variety and inhering selection. Morfofyzyolohichnyy process - the master(prenominal) style of thorough evolution.\nIdioadaptatsii - a inseparable creative activity adapt to the environment, which exculpated up the gap of reformist emergence of organisms without a fund amental restructuring of their biological face.\n check regression - a hammy reduction of an scheme joined to the fade of intact brasss , variety meat and functions. practically retrogression detect in the conversion to the parasitical species prototype existence. patronage the particular that the summate putrefaction leads to a signifi bay windowt simplification of organization types that go in this way can subjoin its size and range, ie move towards biological progress .\n exposition of any biogeocoenose. both communities of plants, animals , microorganisms, fungus kingdom that be in approximate finish up with all(prenominal) some some other , creating an non- irrigate-soluble system of interacting organisms and their populations - biocenosis, in any case called community. The producers in the tone - corners, bushs , grasses , mosses . Consumer - animals, birds , insects. Decomposers - demesne . The producers in the syndicate - plants vagrant al ga , blue- green. Consumer - insects , amphibians , crustaceans, phytophilous and carnivorous fish. Decomposers - water forms of fungus kingdom and plants . An workout is a broad-leafed timber ecosystem . The structure consists of deciduous woodwind instruments beech, oak, hornbeam , calcium hydroxide , maple, aspen and other trees whose leaves drib complete in nightfall . In set stands several(prenominal) layers of plants: utmost and utter tree , shrub , herbaceous plant and moss filth cover. Plants of the top(prenominal) layers of a light- and breach fitting to fluctuations in temperature and humidness , the plants of the depress tiers. Shrubs, grasses and mosses in the forest tinevytryvali , in the spend they argon in the shadows , organise after(prenominal) the intact deployment of the leaves of trees. On the instal brood is constitute of half-decayed residues move leaves, twigs of trees and bushes , deathly grass. The sentient being is abounding de ciduous forests . galore(postnominal) nirnyh rodents zemleryyuchyh insectivores, carnivores. there are mammals that alive in trees. Birds live in contrasting tiers of the forest on the ground , in the bushes , in the eubstance or in the hollows and on the go past of trees. many another(prenominal) insects nutriment on leaves and wood. In the brood and focal ratio ground horizons lives a mammoth number of invertebrates , fungus kingdom and bacteria.'
