[Development of energetics in evolution of the living world. Stage, digits, postulates].

This work deals with the current stage of study of energy exchange between living organisms and the environment. In the epoch of molecular biology, study of energy exchange might have seemed a study of old, well known concepts. However, the retrospective insight into the energy exchange of quite a few organisms allows obtaining new data about development of energetics of the living world, approaches to interesting comparisons, opens the earlier unknown quantitative relations in energetics of living organisms, provides a possibility of analyzing causes of very high values of energy consumption by living organisms, causes of different sensitivity of living organisms to deficit of energy, etc. Based on all these data, there have been noted 12 principal moments or postulates in development of energetics of the living world from the most ancient to the present time.
