Sorting from the standpoint of stability
Sorting from the standpoint of stability is an important mechanism of any evolution, including biological evolution. If structures that differ in their degree of stability are formed in the system, there will be a gradual increase in the content of those that will exhibit greater stability – lifetime. These structures will also be accumulated even if the formation of the more stable structures is statistically less probable than the formation of less stable structures. The sorting is similar to selection, however, only the stability of sorted entities can be the criterion of evolutionary success. The most important difference between the sorting and the natural selection is the absence of any role of heritability in the former mechanism.
