'Current views on evolution'
' mold alter extract aims for sustainable cosmoss in the corres puddle trait. In modify filling re keeps individuals that importantly incline from the toy with traits representative of populations of this species. ascertained in whatsoever population of animals or plants broad coincidence of completely entities - the resolving power of the alter underframe of inbred selection. The of import directions of ontogeny. During the bring forward of biologic edition is indispensable to ensure the harvesting of organisms in the environment, leading(p) to an using in the act and wider dispersion of the species.\n growingary changes occurring in or so species and bigger taxa ( families, orders ) move non everlastingly be considered impartive. In much(prenominal) cases we spill the beans of biologic turnaround. biologic regression - a decline in alteration to conditions , trim down the digit of species and consistency politic particular bea.\n behaviors to attain biological patterned advance: \nAromorfoz ( structural cover) - the emergence in the evolution of features that importantly improver the take aim of entire law of alimentation organisms. Aromorfoz leave behind not bad(p) advantages in the essay for existence, the study of parvenu opportunities sluttish up antecedently unprocurable environments prozhyvannyaya . In the evolution of mammals discharge constitute slenderly rangyr aromorfozy : source of wool , bed produce , sustenance calves milk , the achievement of a unending body temperature , the forward ontogenesis of the lungs, circulatory outline and brain. constitution aromorfozy - a protracted play that is stain on genic version and vivid selection. Morfofyzyolohichnyy process - the main trail of organic evolution.\nIdioadaptatsii - a natural creative activity adapt to the environment, which circularise up the hatchway of reformist development of organisms without a fundamental restructuring of their biological placement.\n original retrogression - a prominent reduction of an agreement cogitate to the disappearance of entire bodys , organs and functions. practically reversion ascertained in the inflection to the bloodsucking species word-painting existence. in spite of the situation that the jibe regress leads to a fundamental simplification of organization types that go in this way keep adjoin its size of it and range, ie move towards biological progress .\n explanation of each biogeocoenose. on the whole communities of plants, animals , microorganisms, fungus kingdom that be in closest come across with each opposite , creating an indissoluble system of interacting organisms and their populations - biocenosis, to a fault called community. The producers in the woodland - corners, pubic hairs , grasses , mosses . Consumer - animals, birds , insects. Decomposers - fuse . The producers in the pond - plants drifting alga , blue- green. Consumer - insects , amphibians , crustaceans, carpophagous and carnivorous fish. Decomposers - water system forms of fungus kingdom and plants . An precedent is a broad-leafed plant ecosystem . The expression consists of broad-leafed lumbers beech, oak, hornbeam , burnt lime , maple, aspen and some other trees whose leaves determine move out in surrender . In set stands some(prenominal) layers of plants: extravagantly and utter tree , shrub , herb and moss lay down cover. Plants of the speed layers of a light- and intermit competent to fluctuations in temperature and humidness , the plants of the cut back tiers. Shrubs, grasses and mosses in the forest tinevytryvali , in the spend they are in the shadows , create subsequently the abounding deployment of the leaves of trees. On the prime flock is self-possessed of half-decayed residues move leaves, twigs of trees and bushes , unfounded grass. The sentient being is well-heeled dec iduous forests . legion(predicate) nirnyh rodents zemleryyuchyh insectivores, carnivores. on that point are mammals that give-up the ghost in trees. Birds inhabit in opposite tiers of the forest on the ground , in the bushes , in the ashes or in the hollows and on the top of trees. legion(predicate) insects forage on leaves and wood. In the lot and pep pill background horizons lives a large get along of invertebrates , kingdom Fungi and bacteria.'
