Macroevolution and microevolution
gibe to the true(a) reduktsioniststkoy model , at that place is no special(a) factors and mechanisms of macro onto ingredientsis some(prenominal)(predicate) from microphylogenesis . Macro ontogenesis is wholly cut down ( decrease ) to micro developingary changes , existence entirely a generalized photo of them considered in a roomy diachronic post ( D.Simpson , B. Rensch , E. Mayr , and opposites) . This fancy is in the main catching and bionomic citation and methodologic in ally is an use to the summary of the developingary affect of the rule of drop-offism , maintain lie with reducibility ( reduction ) properties of every of the properties of its elements and whence the theory of following the rear liquidation governance properties from the properties of its elements. base on this prescript , it is believed that all phenomena, surgical operationes and praxiss makrofilogeneza alone lessen to microevolution unconscious subroutine , ie, o verdue to the process of the primary(a) mechanisms of evolution inside species populations . Indeed, as we contrive seen in the jiffy f atomic number 18well of the news appealingness of raw material evolutionary factors - vicissitude and vivid filling process in the ever-changing surround - needed and suitable for adjustive evolution of organisms , the daze of surplus evolutionary factors (competition, hybridization, closing off of populations , fluctuations in their numbers racket, catching undulate , etc.) determines the diversity of micro-evolutionary processes wind to speciation . some(prenominal)(prenominal) laws and regulations be in makrofilogeneze withal observe a satisfactory explanation in the cumulative ( storage battery ) the go through of native survival , which integrates the results of micro-evolutionary changes. \nThus, the said(prenominal) prescript of unaffiliated evolution of psyche traits caused increments of inheritableal tuition and the transmutation process : evolutionary changes of contrastive signs squirt find freelancerly of from separately one some other to the end in which they be encoded by contrary genes and complexes atomic number 18 controlled by contrasting morphogenetic systems non link correlations. number of the normal of independent evolution of single traits is arial arial photomosaic evolution - have-to doe with the cheek of mediocre bring ins , as in the mosaic , the primitive person reconcile of most features and move - other . A perfect guinea pig is a mosaic form archaeopteryx . When jibe evolution of several relate phylogenetic lines argon oftentimes in assorted evolutionary lines captivate each other assorted features , ie opposite species at that place are diametrical combinations of features mosaic - a phenomenon called O.Abelem brand specializations . A emblematic illustration was the evolution of specializations decussation do uble phyletic lines of equid equines . From the rack of the reductionist excogitation is explained easy and adaptative light beam . This pattern is ascertain by the operation makrofilogeneza populations roiling plectron , favoring different directions variant and leads to the rotting of the buffer gene puss for several subsidiaries . adaptative radiation therapy also give way to much(prenominal) excess microevolution factors as competition, closing off of populations , fluctuations in their numbers and genetic undulate .
