- Abstract
In scientific biological community there is a number of widespread misconceptions concerning the term species. The species as a taxonomic category, defined by a concept, denotes the rank of a species taxon in the Linnaean hierarchy. The modern evolutionary synthesis theory appeared to unify ideas on species from different biological specialities: genetics, cytology, systematics, botany, morphology, ecology and palaeontology. This neo-Darwinian synthesis reconciled Mendelian genetics with the gradual evolution by means of natural selection and explained changes in local populations as broad scale changes or macroevolution. Biological species reproduce isolatedly from each other, which protects the integrity of their genotypes. Taking into consideration only the morphological difference is not an appropriate to define species. Unequal rates of evolution of different characters and lack of information on the mating potential of isolated populations are the major difficulties in the demarcation of species as taxa.
