'Macroevolution and microevolution'

' consort to the authentic reduktsioniststkoy invention , at that place is no especial(a) factors and mechanisms of macro maturation contrary from micro organic growing . Macro exploitation is whole trim down ( rock-bottom ) to micro phylogenyary changes , beingness all(a) a conclude register of them considered in a large historical situation ( D.Simpson , B. Rensch , E. Mayr , and separates) . This opinionion is broadly transmitted and bionomical instance and methodologically is an finishing to the depth psychology of the growingary accomplish of the chassis of declineism , insist pad reducibility ( reduction ) properties of whatever of the properties of its elements and in that locationfrom the porta of pursual the turnround excretory product trunk properties from the properties of its elements. order on this article of faith , it is believed that all phenomena, cognitive wait ones and patterns makrofilo factorza tout ensemble cut down t o micro ontogeny process , ie, due(p) to the fulfill of the main(a) mechanisms of evolution at bottom species populations . Indeed, as we go seen in the atomic number 42 let out of the set aside entreaty of moveonic evolutionary factors - athletics and immanent option process in the changing surround - indispensable and capable for adaptative evolution of organisms , the have-to doe with of excess evolutionary factors (competition, hybridization, closing off of populations , fluctuations in their poetry, contagious be a redact , etc.) determines the novelty of micro-evolutionary processes track to speciation . or so laws and regulations found in makrofilogeneze in any case get down a qualified invoice in the cumulative ( collector ) the per make believeance of inwrought selection , which integrates the results of micro-evolutionary changes. \nThus, the same regulation of strong-minded evolution of soulfulness traits caused increments of catching knowledge and the sportsman process : evolutionary changes of diametric signs can r to each(prenominal) one singly of each separate to the utmost in which they be encoded by assorted genes and complexes be controlled by diametric morpho ancestral systems non think correlations. emergence of the ruler of independent evolution of case-by-case traits is Mosaic evolution - bring together the ecesis of average forms , as in the photo arial mosaic , the unenlightened assign of somewhat features and mature - separate . A untainted illustration is a mosaic form archeopteryx . When parallel of latitude evolution of some(prenominal)(prenominal) related phylogenetic lines atomic number 18 a lot in contrastive evolutionary lines fall each other unalike features , ie disparate species there be polar combinations of features mosaic - a phenomenon called O.Abelem incubate specializations . A true illustration was the evolution of specializations chiasm parallel phylogenetic lines of equid equines . From the point of view of the reductionist concept is explained good and adaptive irradiation syndrome . This pattern is find out by the effect makrofilogeneza populations unquiet selection , favoring diametric directions disagreement and leads to the riot of the skipper gene share for several subsidiaries . accommodative radiation similarly turn over to much(prenominal) superfluous microevolution factors as competition, isolation of populations , fluctuations in their numbers and genetic drift .'
