The hydrothermal origin-of-life hypothesis has been experimentally verified using the hydrothermal flow reactor systems in our group. In this review, the reason why we have examined RNA and proteins from the viewpoint of the hydrothermal origin-of-life and the process for development of the hydrothermal reactors is briefly described. Based on these investigations, the importance of the stability and prebiotic formation of biopolymers under hydrothermal environments on primitive earth, and the interactions and solubility of prebiotic biomolecules will be addressed. Furthermore, the studies led to another requisites for a primitive life-like system as a living system as well as the stability, formation, interaction, and solubility of prebiotic molecules. The stability of the primitive life-like system, which is one of the requisites, would have been the base for continuous chemical evolutions towards a higher level of the system.
