[Nucleotide composition and contents of CpG and CpNpG in the ITS1, ITS2 and 5.8S rRNA of the representatives of phylogenetic branches of melanthiales-liliales and melanthiales and melanthiales-asparagales (angiospermae, monocotyledones) reflects a characteristic feature of evolution].

Variations of nucleotide composition and frequency of CpG and CpNpG sequences in the clusters of nuclear ribosomal genes of taxa, belonging to two phylogenetic branches of Angiospermae have been statistically analyzed. This region of eucaryotic genomes is nucleolus organizer and functions in a separate compartment of cell nucleus that can do running here processes it is enough specific. It is shown that level of evolution advance of a taxon, defined on morphological data, is in positive correlation with quantitative value of dC, CpG and CpNpG. This is found in contradiction with beliefs about the general rules of the transformation of nucleotide composition in evolution, that suggest a CpG suppression. Cryptaffinous taxa being connecting link between a well morphological outlined taxonomic group, differ to be raised in

[The pattern of the lateral phylogenetic branch development]. / O kharaktere protsessa razvitiia bokovoi filogeneticheskoi vetvi.

The lateral phylogenetic branch is S-formed, when regarded in the time-divergency degree coordinates. On the initial side of the curve, the rate of divergency development is low to increase in the middle, and to fall down again on the final side. In result, within one phylogenetic branch all the taxa appear to be typologically diverse.

It is shown that the division of phylogenetical branches descends anisotomically. One new branch becomes evolutionary not active. Another one continues actively to develop. It allows to consider a system of present-day organisms as neonatological annals of evolution. A question arises on distinctions in the constitution of genomes of organisms belonging to active and inactive phylogenetic branches.

It has been shown elsewhere (Chupov, 2001) that the branching of phylogenetical trunks goes by anisotomical way. Thus, in one of newly formed branches a possibility remains of a further evolutionary transformation, while taxa belonging to another branch sink into a prolonged evolutionary stasis. In the author's opinion, such a phenomenon is to be accompanied by distinctions in constitution of genetical cell devices of the taxa belonging to the branches with evolutionary contrasting potencies. In the article, an attempt is done to consider some other approaches relevant to this problem.
