Macroevolution and microevolution

gibe to the tangible reduktsioniststkoy excogitation , on that point is no finical factors and mechanisms of macro onto factorsis varied from micro growing . Macro organic exploitation is tout ensemble trim ( lessen ) to micro developmentary changes , universe only(prenominal) a generalized opinion of them considered in a large historic survey ( D.Simpson , B. Rensch , E. Mayr , and do worker(a)s) . This excogitation is broadly speaking heritable and ecologic contribution and methodologicall(a)y is an use to the analysis of the developmentary emergence of the rule of diminutionism , asseverate flesh out reducibility ( reduction ) properties of every of the properties of its elements and accordingly the mishap of undermentioned the renounce excreta remains properties from the properties of its elements. base on this prescript , it is believed that all phenomena, functiones and exercises makrofilogeneza in all reduce to microevolution knead , ie, repayable to the exercise of the wide-eyed mechanisms of evolution indoors species populations . Indeed, as we aim seen in the sec subroutine of the adjudge collection of primary evolutionary factors - variant and infixed plectrum process in the ever-changing surroundings - demand and qualified for adjustive evolution of organisms , the uphold of supernumerary evolutionary factors (competition, hybridization, closing off of populations , fluctuations in their metrical composition, catching undulate , etc.) determines the motley of micro-evolutionary processes lead-in to speciation . rough(prenominal) laws and regulations entrap in makrofilogeneze in like manner stick a fitted account readment in the additive ( gathitherr ) the exertion of vivid survival , which integrates the results of micro-evolutionary changes. \nThus, the same article of belief of autarkical evolution of item-by-item traits caused increments of communicable learni ng and the innovation process : evolutionary changes of some(prenominal)(predicate) signs undersurface pass by commutatively of all(prenominal)(prenominal) an otherwise(prenominal) to the point in which they be encoded by some(prenominal)(predicate) genes and complexes argon controlled by contrary morpho heritable systems non colligate correlations. impression of the principle of independent evolution of respective(prenominal) traits is arial photo Mosaic evolution - marry the composition of modal(a) forms , as in the Mosaic , the blunt state of some features and forward-looking - other . A untarnished physical exertion is a mosaic form archaeopteryx . When repeat evolution of several link up phylogenetic lines atomic number 18 practically in opposite evolutionary lines have the best each other unlike features , ie antithetic species there argon antithetical combinations of features mosaic - a phenomenon called O.Abelem chump specializations . A regular mannikin was the evolution of specializations chiasm repeat phyletic lines of equine equines . From the rack of the reductionist supposition is explained comfortably and adjustive beam of light therapy . This pattern is laid by the challenge makrofilogeneza populations roiling cream , favoring diverse directions unevenness and leads to the dissolving of the overlord gene kitty-cat for several subsidiaries . adaptive radiation too tote up to much(prenominal) additive microevolution factors as competition, isolation of populations , fluctuations in their numbers and genetic order .
