Evolution of the biosphere and entropy

We analyzed the possibility of explaining empirical relations in the evolution of the biosphere using mathematical models based on the use of the information entropy of event chains and transformation probabilities. It was shown that the requirement of a monotonous increase in entropy is satisfied, if the probability of transitions in such chains increases, especially strongly at the first stages of development. It was demonstrated that a feedback corresponding to death has to be introduced into the chains of implications, and its probability must be significantly higher than that of transitions between evolutionary stages. The problems of the existence of limits of major evolutionary stages and connections of this phenomenon with fundamental physical principles were discussed. The obtained results agree with the observed characteristics of evolutionary processes, which indicates the plausibility of the mathematical model.
