The microscopic components--metabolic micelles or proteinoid microspheres, with perhaps the information bearing days of Cairns-Smith--would occupy the original locus of meaning.
Then we can consult numerous works showing how the spontaneous origin of proteinoids and amphoteric substances (layers and micelles of surface active liquid crystalline precursors of cell membranes) can have taken place, within which the autocatalytic cycles became protected.
The aggregation of proteinoids [3] into microspheres under the hydrophobic tension of an aqueous environment also created entropy at the expense of free energy.
