Hot-spring hypothesis or Hydro-thermal vent hypothesis?

  • Hot-spring hypothesis is more probable.

    RNA has been synthesized in simulated prebiotic hot spring environments, Hot-springs would also allow cycling of new molecules and removal of old molecules while providing a gradient in which non enzymatic RNA replication can occur, Also fatty acid liposomes are most stable in fresh water.

    RNA or similar polymers have not been synthesized under simulated hydro thermal vents, Hydro-thermal vents lack cycling systems and sufficient compartmentalization while being too acidic for fatty acid liposomes.
