"This theory suggests that life arose deep in the
ocean with hydrogen rich molecules. Their rocky nooks could then have concentrated these molecules together and provided mineral catalysts for critical reactions.
Alkaline fluids from the Earth’s crust flow up towards the more acidic ocean water, creating natural proton concentration differences remarkably similar to those powering all living cells.". This statement belongs to:
Theory of biochemical evolution
Community clay
Deep sea vents
RNA world
