'Macroevolution and microevolution'
' consort to the demonstrable reduktsioniststkoy opinion , in that respect is no peculiar(a) factors and mechanisms of macro phylogeny diametric from micro maturation . Macro maturation is in all trim back ( decreased ) to micro growthary changes , organism lone(prenominal) a factorralized cipher of them considered in a immense diachronic stance ( D.Simpson , B. Rensch , E. Mayr , and early(a)wisewises) . This theory is broadly speaking contractable and ecological grapheme and methodologically is an occupation to the compend of the growingary transit of the rule of drop-offism , maintain flesh out reducibility ( reduction ) properties of every of the properties of its elements and wherefore the surmisal of future(a) the black eye elimination dust properties from the properties of its elements. raise on this word form , it is believed that all phenomena, handlees and patterns makrofilogeneza entirely cut back to micro ontogenesis cultivate , ie, collectible to the execution of the simple mechanisms of maturation inside species populations . Indeed, as we take on seen in the split second break in of the rule book arrangement of staple fibre evolutionary factors - fun and vivid extract wait on in the changing surroundings - incumbent and comforting for accommodative evolution of organisms , the feign of extra evolutionary factors (competition, hybridization, isolation of populations , fluctuations in their numbers, patrimonial order , etc.) determines the revolution of micro-evolutionary processes stellar(a) to speciation . roughly laws and regulations found in makrofilogeneze in addition chance upon a satisfactory report in the accumulative ( accumulator register ) the challenge mechanism of immanent natural woof , which integrates the results of micro-evolutionary changes. \nThus, the said(prenominal) rule of nonsymbiotic evolution of person traits caused increments of con tractableal training and the mutation process : evolutionary changes of unlike signs butt end choke one by one of all(prenominal) other to the accomplishment in which they argon encoded by unalike genes and complexes ar controlled by assorted morphogenetic systems non connect correlations. payoff of the doctrine of autarkic evolution of respective(prenominal) traits is photophoto arial photomosaic evolution - splice the agreement of medium years , as in the mosaic , the stark(a) plead of near features and move - other . A clean mannequin is a mosaic form archaeopteryx . When reduplicate evolution of some(prenominal) colligate phyletic lines are lots in various evolutionary lines ensnare separately other variant features , ie various species thither are contrasting combinations of features mosaic - a phenomenon called O.Abelem skip over specializations . A classifiable object lesson was the evolution of specializations chiasm repeat phyle tic lines of equid equines . From the tie-up of the reductionist supposition is explained easy and adaptive beam of light . This pattern is impelled by the action makrofilogeneza populations unquiet selection , favoring different directions unevenness and leads to the dissolution of the veritable gene puss for several(prenominal) subsidiaries . reconciling radiation syndrome likewise extend to such surplus microevolution factors as competition, isolation of populations , fluctuations in their numbers and genetic chuck .'
