Evolution of an RNA population in a network of inorganic compartments. Open arrows show thermoconvection, and horizontal filled arrows show thermophoresis. Compartment 1, accumulation of mononucleotides; compartment 2, accumulation of abiogenically synthesized RNA molecules; compartment 3, exploration of the RNA sequence space by ligation and recombination of RNA molecules; and compartment 4, emergence of the RNA world. The putative ribozyme replicase is denoted by a “globular” RNA molecule, possibly emerging by the ligation–recombination process. The stack of compartments depicts a contemporaneous, three-dimensional network. However, within the compartments, putative successive stages of evolution are shown, in the direction from the inside (near the vent) to the outside of the network.
