Reciprocal Relations in Evolutionary Processes

چکیده
In nature, our biological world consists of many species of biological contents such as DNA, RNA, and proteins, etc. We frequently ask a question: “Which is first, egg or chicken?” In the evolution of life, we also encounter a similar question: “Which is first, RNA, DNA, or protein?” or “How do they co-evolute?” In such biological systems, a theory of co-evolution of biopolymers is necessary. However, we have not yet been able to tame such a tough issue in the problem. Recently, Aita et al.1) have proposed a thermodynamic theory-like interpretation of evolutionary processes such as evolutions of proteins and biopolymers.∗) They found appropriate definitions for the concepts such as free fitness, evolutionary temperature, constant, entropy, force, and flux, etc. Using such quantities in evolutionary processes, they found a linear relationship between the evolutionary force and flux such as the linear response theory in thermodynamics. Their theory suggests that there may exist “a theory of irreversible processes” in evolution of a “single species” in biology. It can be thought of as a generalization of Onsager’s theory2),3) of irreversible processes to that of evolutionary processes. So, as a first step toward such a direction, I would like to postulate a generalization of Onsager’s theory of irreversible processes-like approach1) to the theory of evolutionary/co-evolutionary processes. In this paper, if there is no confusion, I would like to mean “co-evolutionary”(or “co-evolution”) simply by “evolutionary”(or “evolution”). Finally, I would like to give some comments on the relationship between Aita-Husimi’s interpretation,1) Kauffman’s point of view of generalized thermodynamics4) and Fuller’s synergetics philosophy.5),6) They are essentially all the same.

Estimating Unknown Values in Reciprocal Intuitionistic Preference Relations via Asymmetric Fuzzy Preference Relations
Intuitionistic preference relations are becoming increasingly important in the field of group decision making since they present a flexible and simple way to the experts to provide their preference relations, while at the same time allowing them to accommodate a certain degree of hesitation inherent to all decision making processes. In this contribution, we prove the mathematical equivalence be...

One-way facilitation in plants has been found in many harsh environments and their role as structural forces governing species composition in plant communities is now well established. However, reciprocal positive effects benefiting two interacting species have seldom been reported and, in recent reviews, conceptually considered merely as facilitation when in fact there is room for adaptive str...
متن کاملConfidence-consistency driven group decision making approach with incomplete reciprocal intuitionistic preference relations
Intuitionistic preference relations constitute a flexible and simple representation format of experts’ preference on a set of alternative options, while at the same time allowing to accommodate degrees of hesitation inherent to all decision making processes. In comparison with fuzzy preference relations, the use of intuitionistic fuzzy preference relations in decision making is limited, which i...
متن کاملRelational Databases Query Optimization using Hybrid Evolutionary Algorithm
Optimizing the database queries is one of hard research problems. Exhaustive search techniques like dynamic programming is suitable for queries with a few relations, but by increasing the number of relations in query, much use of memory and processing is needed, and the use of these methods is not suitable, so we have to use random and evolutionary methods. The use of evolutionary methods, beca...
