Postulates: Pairwise structures are the basic components of living systems. As the lowest level of living structures, they obligatory must offer more than one opportunity of survival (1/1, 1/2, 2/2), minimizing the possibility to disappear under Darwinian selection. Functionally monomorphic molecules, as minimal and basic structure (A1 or A2) may extremely change their frequency under natural selection, and disappear in non-convenient conditions, being a non-satisfactory basic component of living systems.
