title: [The dynamic trends of biological evolution].
abstract: The available data on the thermodynamic stability of supramolecular biological structures and variations in the chemical composition of living organisms have allowed a macrothermodynamic model of biological evolution to be developed experimentally. In this model, the tendency toward a minimum of the specific Gibbs function of the formation of supramolecular structures of living organisms causes variations in the chemical composition and structure of living systems. It is shown that in the course of ontogenesis and phylogenesis, as well as long-lasting stages in the evolution of the organic world, the biosystems (as a result of the thermodynamic direction of evolutionary processes of the formation of supramolecular structures) are enriched with energy-intensive chemical substances, which displace water from these biosystems. The change in the composition and structure of biostructures of an adaptive character is also explained from the angle of macrothermodynamics.
