Life may have originated from the ocean floor
WebThis theory is consistent with the idea that life may have originated near hydrothermal vents in the ocean floor. While Wächtershäuser's experiments did succeed in producing simple and more complicated amino acids, those acid chains were noted to hydrolyze quickly in the surrounding chemical environment.
