N2 - Natural selection is a buzzword used to describe the main driving force of evolution. Its creative role is believedto be based on: a) an unlimited variety of organisms caused by hereditary variation and b) a direct connectionbetween hereditary changes and their phenotypic expression. These are the two requirements that can lead tothe genetically based changing modalities of characters through “iterations” of natural selection in the series ofsuccessive generations. Are these two requirements fulfilled in the nature, however? The present study focuseson the analysis of these two “foundation stones” of natural selection. Firstly, hereditary variation is shown to beessentially non-homogenous. New hereditary characteristics of individuals fall onto a narrow “strip of land” in thesea of potential possibilities. Secondly, the consequences of changes in the genotype of an organism areinvolved into a system of hierarchical multiple compensation, from the molecular to the biocenotic level. In away, the signal of hereditary change passes through a series of “system filters” at epigenetic, ontogenetic,physiological, behavioural, populational and biocenotic level. Each filter is represented by multiple feedbacksmaintaining the integrity of systems at each level and at all the hierarchical levels taken together. It is in these“system filters” the adaptive nature of characters is formed representing the every individual as a subject to theLaw of Multilevel Self-Organization. The emerging understanding of this provides a strong reason to change theevolutionary paradigm from the mainly selectogenetic to the mainly orthogenetic one.
