Life & Consciousness
Hydrothermal Vent (Metabolism-First) Origin
Suggests life began not in a surface “soup” but at alkaline hydrothermal vents on the ocean floor, where mineral structures provided ready-made chemical gradients for early metabolism.
Proponents
Günter Wächtershäuser, Michael Russell, William Martin, Nick Lane
Evidence For
Alkaline vents naturally generate proton gradients resembling those all living cells still use for energy, and provide catalytic mineral surfaces.
Evidence Against
Direct evidence that the first self-replicating systems actually formed at vents (rather than elsewhere) is circumstantial.
