This paper provides a qualitative analysis of one of the possible channels of negative entropy (negentropy) to ensure the evolution of biological systems. In particular, it is shown for the first time that a periodically changing flow of equilibrium radiation carries a reduced entropy content in comparison with a constant flow of the same power. This conclusion is made based on the analysis of the Shannon entropy time dependence graph for the model under consideration. The study relevance is due to the well-known contradiction between the statement of the second principle of thermodynamics about the tendency of closed systems to a state with maximum entropy (chaos) and Darwin’s evolutionary theory describing the complexity of biological systems. This problem is worked out in many aspects and devoid of the status of an inexplicable paradox. However, a number of important questions, including the sources of negative entropy, remain open. As a function describing the frequency of incident radiation, a simple harmonic is chosen, which does not quite correspond to the daily change in illumination observed on the Earth, but allows us to draw conclusions about the qualitative nature of its influence. The result obtained can be of great importance for evaluating the equilibrium parameters and stability of open thermodynamic systems.
