概要	The origin-of-life hypotheses regarding RNA and protein molecules, that is, the RNA world hypothesis and GADV protein hypothesis have problems from the viewpoint of hydrothermal origin-of-life hypothesis. In other words, these hypotheses have not provided practical models, which could have survived under the extreme conditions on primitive Earth. Even if life could have originated under much milder conditions, the question how such system initially consisting of simple biopolymers could have evolved to a primitive system to regard as life has not been extensively focused. The stability and continuity of life-like system is essential to possess the nature that living system is capable to adapt itself to and survive against the change of environments. The analysis showed possible implication of such pathways and the sce- nario from molecules to a system possessing the essential characteristics for life.
