The current taxonomic system, based on the hierarchy of Linnaean ranks, is said to be unsatisfactory. Many people insist that the very concept of rank should be eliminated, and the current taxonomic system should be replaced with a rankless system based on phylogenetic taxonomy. However, it is not the elimination of the concept of rank but rather t...

Ascomata of 10 species assigned to family Nitschkiaceae were examined with a scanning electron microscope to reveal their distinctive features. These observations, along with biogeographical considerations of the 10 species, form the basis for a revised interpretation of the concepts used for those nitschkiaceous taxa in the Russian Far East. Four...

In this paper, the Linnaean hierarchy is discussed as the taxonomic model for the evolutionary differentiation of the earth’s biota. This model allows us to understand why a number of ideas and arguments in the evolutionary theory are unfortunate. Among these is the idea of a linear ladder of nature («scala natura»). The arguments about species con...

In biological literature, essentialism and typological thinking are believed to be incompatible with evolutionary. ideas. At present, the same considerations underlay the claims to abandon the Linnaean hierarchy, or the fundamental classificatory structure rooted in essentialism. This paper suggests to reconsider the negative views of Plato's typol...
