Ontogeny, Systematics, and Phylogenetics: Perspectives of Future Synthesis and a New Model of the Evolution of Bilateria

摘要

Ontogeny is considered as a process that allows linking two key components of biological systematics in an objective way: historically independent character attribution and phylogeny. It is proposed to designate the general theory that unifies the "static" traditional taxonomy and the dynamic evolutionary process on the basis of ontogenetic transformation of shapes of organisms as the ontogenetic systematics. One of the important practical applications is a new model of the evolution of bilaterian animals, which supposes an ancestral status of clonal asexual reproduction and its multiple reduction in different lines of Bilatera.
