Abstract: | The Darwinian theory of life evolution is capable of explaining the majority of related phenomena. At the same time, the mechanisms
of optimizing traits beneficial to a population as a whole but not directly to an individual remain largely unclear. There
are also significant problems with explaining the phenomenon of punctuated equilibrium. From another perspective, multiple
mechanisms for the regulation of the rate of genetic mutations according to the environmental stress have been discovered,
but their precise functional role is not well understood yet. Here a novel mathematical paradigm called a Kinetic-Force Principle
(KFP), which can serve as a general basis for biologically plausible optimization methods, is introduced and its rigorous
derivation is provided. Based on this principle, it is shown that, if the rate of random changes in a biological system is
proportional, even only roughly, to the amount of environmental stress, a virtual force is created, acting in the direction
of stress relief. It is demonstrated that KFP can provide important insights into solving the above problems. Evidence is
presented in support of a hypothesis that the nature employs KFP for accelerating adaptation in biological systems. A detailed
comparison between KFP and the principle of variation and natural selection is presented and their complementarity is revealed.
It is concluded that KFP is not a competing alternative, but a powerful addition to the principle of variation and natural
selection. It is also shown KFP can be used in multiple ways for adaptation of individual biological organisms. |
