It became formed as the science about evolution of species’ diversity and methods of investigation of it. Here is defined its object, subject, aim and method. Theoretical evolutional systematics is separated from practical systematics. Three sections are included in its content: idiographical systematics, nomothetical systematics and phylogenetical cybernetics. Idiographical systematics includes theories of descriptions (= meronomy), classifications (= taxonomy) and reconstructions of phylogenesis (= phylonomy). Nomothetical systematics includes the laws of phylogenetics, postulates of systematics, axioms and theorems of evolutional systematics in a whole, forming deductive theoretical system of evolutional systematics (DTS ES). Status of laws is added to 21 conformities to natural laws of phylogenetics. Here are formulated 6 postulates of systematics. On the base of logical investigations of laws and postulates as statements, the laws of phylogenetics are represented in form of 6 axioms and 15 theorems. Postulates of systematics are considered as 6 axioms. DTS ES is represented in the paper on the base of analysis of connections between 12 axioms. Phylogenetical cybernetics includes interpretation of the theory on the some systemic and probabilistic models of species, their classification and reconstruction of phylogenesis, the examples are present in the article. It is divided on three sections of investigations : systemology, theory of control phylogenetical transformations and theory of information processes in phylogenesis. The sections of evolutional systematics are interpreted accordingly philosophical conception of the levels of scientific knowledge. Systematics and phylogenetics are considered as two aspects of evolutional systematics as united science, reflecting its onthology (= the laws of phylogenesis) and gnosiologyl (= postulates of systematics). This solution conforms to initial definition of evolutional systematics as the science of evolution of species’ diversity and methods of its investigation and conforms the contemporary darwinism.","PeriodicalId":344032,"journal":{"name":"Species and speciation.

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 constancy versus species variability, natural species versus «artificial» higher taxa, a single type of animals versus multiple types, as well as about the connection versus disconnection of microevolution and macroevolution are meaningless. Two kinds of phylogeny are considered. The first reflects the appearance of new characters in the course of evolution, and their sequence provides the nesting hierarchy of groups. The second reflects the appearance of new character states and provides a basis for the diversity of taxa at each hierarchical level. The taxonomic hierarchy is an embodiment of the first kind of phylogeny and does not require the tracing of ancestors and descendants along the lines of character development. Character ranking and the improvement of a tentative taxonomic hierarchy with the help of a posteriori weighting of differences are discussed. The method of character weighting leads to the construction of prognostic combinatorial arrangements that can predict the existence of organisms with certain character state combinations at each hierarchical level. The drawbacks of cladistic methodology, especially the «synapomorphy principle», the «dichotomy principle», and the monophyly «definition» through the internal composition of groups, are noted. It is pointed out that these principles only lead to the creation of heterogeneous groups and wrong character ranking.","PeriodicalId":344032,"journal":{"name":"Species and speciation.

This work is of importance in modern taxonomy as a source of descriptions of 935 genera (in all a total of 1336 Linnaeus’ genera of plants were diagnosed). Basically the Linnaean concept of the genus was in accord with the French botanist J.P. Tournefort that the fundamental category of classification was the genus, and that plants having in common two or three characters of reproductive structures were usually to be treated as members of the same genus. Linnaeus so– called sexual system «of plant classification» comprised 24 classes, 23 of which contain the flowering plants, with stamens and pistils was highly artificial was expanded and served as the basis for «Genera plantarum». At the same time Linnaeus preparing the manuscript for a sumptuous work «Hortus Cliffortianus» (1737), in which were named and described many temperate and tropical plan grown in the botanical garden by George Clifford, Director of the Dutch East India Company. The genus Сliffortia was selected to honour of the owner of plant collection. The Genera of Linnaeus were based largely on the belief that a genus is a category whose components (species) have the essential character, it discriminated between species to morphological distinctions of leaf forms: С. ilicifolia, C. polygonifolia, С. ruscifolia, С. trifoliata; discriminated through stem habit types: Phascum acaulon, P. caulescens, P. repens; geography and its relationship to plant distribution: Parietaria cretica, P. lusitanica, P. zeylanica – in a literal sense is illustrated Linnaeus’ metaphora: «plantae omnes utrinque affinitatem monstrant, uti Territorium in Mappa geograpica» («Philosophia botanica » (PhB) Systemata. II. 77). It is evident that according to Linnaeus’ concept of the genus the naming of plants must be reflected a significant selected characters(«Nomen specificum legitimum plantam ab omnibus congeneribus distinguat”(PhB) Differentia. VIII. 257). It is likely that the Linnaeus’ metod integrated an elements of system, was elucidated the structure of a genus as a natural and phyletic unit. Therefore this concept provides the basic for modern plant classification and flowering plant phylogeny. However, a few years later Peter Simon Pallas (1741–1811), a professor of St. Petersburg Academy of Sciences in his taxonomical works recognized several species in the genus Polycnemum (now partly Petrosimonia Bunge; Chenopodiaceae). Perhaps engage in controversy against Linnaeus’s study and pursue polemical goals he named plants with according to number of stamens: P. monandrum Pall. – with only one stamen in androecium; P. triandrum Pall. – with three stamens. It was a corrective action on the advancement of the method of natural classification and, on opposite sides, a parody on the Linnaeus’s artificial classification.

This is a higher-order variety of racial structures or «eidologic» units typical of plants in connection with multiplicative processes as hybridization and specific features of biological isolating mechanisms of races (and species), polyploidy of different origin, agamic-and clonal types of asexual breeding etc. After the brief historical review of botanical works on these problems it is emphasized, what of diversity of plants the nature of micro-evolutionary transformations to populations has unequal basis (where frequently populations considerably hybrid breakdown, two ore more species etc.) and, actually, the speciation. Basic natural units of evolutionary process at plants are not only species (mono- or polytypical), but also it is long existing complexes of populations of the different species, interacting with each other (down to complex of syngameons uniting species of a genus or even different genera). The first who has definitely distinguished species and species-complexes was Wladimir Komarov. Now it is possible to distinguish at vascular plants some types of species (up to 7), and species-complexes (i.e. the basic eidological units, it is real evoluting in the nature). Consequently it is possible to discuss about the greater potentiality for evolutionary transformations for a vascular plants, than one at a vertebrate animals.","PeriodicalId":344032,"journal":{"name":"Species and speciation.

The waves of species splitting and lumping always altered depending both from dominant species concept, fashion and methods applied. Starting from the end of the last century the description of species diversity is at the peak of splitting wave. The specific feature of current splitting wave is that it relies 1) on new wide array of characters – molecular markers with their universality and easy application; 2) wide application of molecular markers in its turn gave birth to new methodology – phylogenetic analysis penetrates to intraspecies level, new direction of studies – phylogeography (Avise et al., 1987) appears and explosively develops. Phylogeography very successfully fall on phylogenetic species concept using gene trees as the basis for delimiting species and this «tree-thinking» approach together with widely expanding studies on phylogeography lead to dramatic increase in species number practically in all groups of vertebrates. Unlike morphological characters, molecular markers are universal (occur in all or almost in all organisms) and genetic distances, therewith, at a first glance gave an universal metrics for delimiting species which could be applied to almost all groups. Thus remarkable and long-awaited perspective opens- systematics receive an universal tool for distinguishing and delimitation of species. However, this hope on universal criteria once again appeared to be false and all issues which rise while working with molecular markers are very similar to those one have using morphological approach. In other words application of molecular markers bring us back to old and well known issues major part of which currently has no solution and the feeling that biologists at last have gain a unit similar to exact sciences is very wrong.","PeriodicalId":344032,"journal":{"name":"Species and speciation.

The biological integrity is considered as an all-round concordance between constituents of structure, functioning, reacting and development, while an organism is seen as a dynamic-steady system of integrative relations between genome and phenome based on mutual influence. Any transformation or emergent self-organization within a living system is connected with the maintenance of its steady state. The adaptive constituent of the system’s steady state concerns to its fitness, and the structural constituent – to its steady-state structure. The only difference between ontogenesis and formation is that the object of the first one is an organism, while the object of the second one is a reproducing totality of organisms, which is elementary in the frame of typology and historically conditioned within a definite space. A species is considered as typologically indivisible and historically unrepeatable variant of steady relations between genome and phenome, which canalize the diversity of their own systemically permitted transformations. The «epigenetic» constituent of divergence between species is determined by difference in relations between phenome and genome, not by change of the latter’s compound. The «products» of epigenetic speciation distinctly differ in morphology and ecology, having a lack of post-zygotic reproductive isolation. The reproductive isolation between them is caused by ecological and ethological barriers. The genetic constituent of divergence between species is incompatibility between nonconspecific genomes, which more often is revealed in a form of hybrids sterility. The prevailing of the genetic constituent of interspecific divergence is caused by allopatrie in uniform environmental conditions. In such case, the genomic divergence is accompanied by invariable relations between genome and phenome, that determines morphological and ecological uniformity of cryptic species. The divergence between panmictic species more often includes both of the constituents in different ratio. Due to its universality, the systemic approach to the problem of species is also appropriate to apomictic organisms.","PeriodicalId":344032,"journal":{"name":"Species and speciation.
