生物的进化和退化-基因组合进化论?

Since the establishment more than 150 years ago, the Darwin's theory of evolution has made many major changes in the concepts and structure. However, there have been two major remaining problems including the thermodynamic fundament of evolution and the molecular biological mechanism for development of new species. Some important new evidences such as the Cambrian explosion of life were hardly incorporated into the current theory of evolution. Based on a new analysis on the thermodynamics of life development and degeneration, the present paper proposed a novel and complete hypothesis---the gene recombination theory of evolution. The basic points of the new theory include: ①life is the expression of intrinsic life of surroundings which is in the chaos state. The evolution of life depends on the potential complexity and the capacity of the surroundings; ②After occurrence of life, the life species and the surrounding form a complete ecological structure following the order of energy/entropy flux; ③Evolution is for both individual species and the whole ecological system; ④By new genes transfer between individuals and species, new species may be developed through gene recombination in certain circumstances; ⑤Biodiversity is both the result and one key cause of life evolution; ⑥The limit of evolution moves a cycle of catastrophe of mass distinction of old species and the development of new ecological structure through the mechanism of "competition for survive".
