law of phase
Закон смены фаз или направлений эволюции, правило чередования главных направлений э.; з. А. Н. Северцова — закон, утверждающий, что в истории монофилетической группы организмов за периодом крупных эволюционных перестроек — арогенеза, ароморфоза — всегда наступает период частных приспособлений — аллогенезов, алломорфозов, катагенезов, гипергенезов и т.п. Освоение новой среды или крупные морфофизиологические преобразования всегда ведут к вспышке видообразования. Закон сформулирован А. Н. Северцовым в 1925 г. Значительный вклад в его дальнейшую разработку внес И. И. Шмальгаузен.
