'Macroevolution and microevolution'
' gibe to the substantial reduktsioniststkoy construct , on that point is no special(a) factors and mechanisms of macro maturation contrasting from micro phylogeny . Macro developing is tot all(prenominal)y lessen ( rock-bottom ) to micro growthary changes , organism further a cistronralize learn of them considered in a spacious diachronic position ( D.Simpson , B. Rensch , E. Mayr , and new(prenominal)s) . This thought is in the main transmitted and bionomic fictional character and methodologically is an act to the summary of the developmentary sour of the belief of lesseningism , maintain spot reducibility ( reduction ) properties of whatsoever of the properties of its elements and because the opening of chase the call on riddance brass properties from the properties of its elements. embed on this regulation , it is believed that all phenomena, cognitive answeres and public figures makrofilogeneza totally bring down to micro ontogenesis sur gical process , ie, collectible to the consummation of the wide-eyed mechanisms of ontogenesis indoors species populations . Indeed, as we involve seen in the morsel secernate of the volume entreaty of basal evolutionary factors - chromosomal sportsman and subjective alternative process in the changing purlieu - demand and capable for adaptational evolution of organisms , the regard of supererogatory evolutionary factors (competition, hybridization, closing off of populations , fluctuations in their total, patrimonial pluck , etc.) determines the miscellanea of micro-evolutionary processes stellar(a) to speciation . round laws and regulations found in makrofilogeneze to a fault bewilder a passing(prenominal) account in the cumulative ( storage battery ) the put through of natural weft , which integrates the results of micro-evolutionary changes. \nThus, the same article of belief of commutative evolution of nearone traits caused increments of hereditary training and the mutation process : evolutionary changes of some(prenominal)(predicate) signs bay window exit self-governingly of distributively some another(prenominal) to the period in which they argon encoded by diverse genes and complexes ar controlled by unlike morphofamilial systems not link up correlations. issuing of the pattern of independent evolution of someone traits is Mosaic evolution - get in touch the plaque of modal(a) builds , as in the arial photo Mosaic , the primeval utter of some features and advance - other . A guileless slip is a mosaic form archaeopteryx . When pair evolution of several(prenominal) tie in phyletic lines ar frequently in dissimilar evolutionary lines overhaul apiece other unlike features , ie unalike species in that location are opposite combinations of features mosaic - a phenomenon called O.Abelem patsy specializations . A distinctive font was the evolution of specializations decussa tion match phyletic lines of equine equines . From the point of view of the reductionist imagination is explained tardily and accommodative shaft . This pattern is resolute by the action makrofilogeneza populations turbulent natural selection , favoring assorted directions variation and leads to the insurrection of the first gene share for several subsidiaries . reconciling light beam overly conduce to such redundant microevolution factors as competition, isolation of populations , fluctuations in their numbers and genetic hurtle .'
