title: [Hypothesis of possible evolution and functional specialization based on the recombination and transposition of elementary functional blocks].
abstract: A number of examples demonstrating that different cell and organ functions are being performed by a limited set of identical or similar functional blocks has been analysed. The latters are molecular or supramolecular structures fulfilling elementary functions. Functional evolution, functional and structural specializations, divergence, convergence and other processes have been considered as associated largely with the relationship, recombination and transposition of such elementary functional blocks, presumably, originated at the early stages of evolution.
