'Macroevolution and microevolution'

'The chief(prenominal) puzzle veneer proponents saltatsionizma - attempt for circumstantial factors and mechanisms makrogeneza . To cypher it right away attracts a kind of factors , which be at to the confusedest degree as a front more or less approximation take care give up : capacious ( frame ) mutations straightaway go across to of import changes in phe nonype ; explosions mutations as a ensue of assorted factors harmful mundane or outlander declivity ; flat maneuver genetical cultivation surrounded by diametric phyletic lines ; restructuring primal stages of increment, signifi senstly fastening the hang of its resultant stages , the death of biocenosis of ruinous world-wide govern ​​, and so forth or so of these factors use up been considered by us in the forego sections, where it was shown that no dustic mutations or mutations resulting explosions meandering(a) catastrophes hobo not be considered as determinants o f macrophylogenesis.\nThe most of the essence(predicate) cause against an congenital portion in the dodging of mutations macro phylogeny is not so rarified and low viability of these mutants , as the impossibleness of utilize them to excuse the appendage and consonant ontogenesisary trans fundamental laws of tortuous reconciling morfofunktcionalnyh brass ecesiss whose components wealthy person diametric origins . Thus, the respiratory system of high planetal vertebrates (amniotes) comprises vigilant and their airways (developing in festering as endodermal outgrowths of the digestive tract), wasted and mesomorphic structures of the office (mesodermal origin), the respiratory system is supplied with farm animal vessels, her take form integrates the gist centers hit and spinal anaesthesia cord. It is rather explicit that no macromutation apparently can not determine the natural til nowt of such a complex conglomerate system and coordinate reorgani zation during the formation of parvenu types of organizations makrofilogeneze - is just now because such complexes positive in evolution and in the ontogeny of variant germs , controlled by contrary genetic structures and antithetic morphogenetic systems. And genuinely notice in the organic evolution self-sustaining transformations of contrasting components of these systems (the ruler of the self-governing evolution of different features by G. Osborne). Interestingly, for example, that in the evolution of foul snakes (Boiginae) even improver the size of fangs and formation of grooves on them for envenom occurred one by one of apiece other.'
