Hydrothermalism for the Chemical Evolution Toward the Simplest Life‐Like System on the Hadean Earth
Abstract
The discovery of functional RNA molecules led to the RNA world hypothesis. For constructing the most primitive life-like system, functional RNA molecules played important roles in the emergence of primitive life-like system on the Earth. Hydrothermal environments involve a variety of chemical and physical conditions, a wide range of temperatures and pressures, time ranges and other chemical conditions in relation to the presence of different minerals and dissolved materials. Future approaches for the investigation of RNA-based life-like systems from the viewpoint of hydrothermalism are illustrated. The hydrothermal system is originated in contact with high-temperature minerals; thus, the minerals should have played important roles in the hydrothermal system for the emergence of life-like systems on the Hadean Earth. Thus, hydrothermal environments could have played an important role in chemical evolution at the very beginning of the Hadean Earth.
