Abstract

The neutral mutation-random drift hypothesis cannot explain biological evolution, particularly in the relationship between evolution at the molecular level and phenotype, adaptability, and evolution. Gene random drift cannot be the driving force of biological evolution but exists as polymorphic types in the population and becomes a source of automatic regulation. Biological evolution is neither governed by random variations nor dominated by the environment; rather, it is precisely the manifestation of a biological automatic control process. The role of environmental conditions is neither that of the "creator" nor the "editor" of biological evolution; instead, it serves as a stimulus or inducing factor that promotes biological evolution and is also a target during the automatic control process. Prevalent neutral mutations in nature provide a wide source of selection possibilities for biological evolution during the process of self-regulation and adaptability. A preliminary approach to a mathematical model of biological evolution cybernetics will help us understand the real evolutionary phenomena of organisms more comprehensively.
