THE PATTERN TRANSFORMATIONS AND QUANTUM M ACROEVOLUTION

The quantum typogenesis is an epiphenomenon resulted from different ev olution mechanisms that are based on system peculiarities of organisms and demonstrate a threshold effect. One of such mechanisms is caused by radical transformations of functional pattern in some phenotype sys tems taking place on the base of small morphological and genetic chang es. Pattern. transformations provide the possibility to evolve a new t ype of adaptation playing role of macroevolution trigger. The patterns of such transformations are exemplified changes in biomechanical pecu liarities and function regime of jaw apparatus under transformation of pleurometakinetic skull into amphikinetic one, evolving of hyperstrep tostyly from the simple streptrostyly and loss of cranial kinesis in t he phylogeny of amphibians and reptiles.
