[On the change in the isotopic composition of living beings during aging and evolution].

The article notes that the change in the isotopic composition of living beings during aging and in the evolution was predicted on the basis of the "principle of stability of matter". This principle was formulated by the author in the late 70's of the last century. New quantitative estimates were made, confirming the above prediction. To date, there are many studies that confirm those previously formulated approval by the author. These facts are a new confirmation of the thermodynamic theory of the origin of life, its evolution and aging of living beings.
