New research suggests that the origins of life on Earth were significantly influenced by metals found at deep-sea hydrothermal vents. These metals, including nickel, iron, and cobalt, acted as catalysts for essential chemical reactions, effectively performing the functions of enzymes before complex biological machinery evolved. The study indicates that early life forms, like bacteria and archaea, inherited incomplete metabolic pathways and relied on these metallic compounds within serpentinite rocks to convert carbon dioxide into organic matter and manage energy transfer via phosphate-like molecules.
