2) A population of RNA-like polymers adsorbed at a ZnS template could
gather light and therefore enhance the yield of the photocatalysis. Since
the hydrothermal ZnS structures are highly porous [179-181], the pores/
compartments that contained efficient replicators and, hence, an increasing
number of UV-absorbing zymes could produce more metabolites,
which, in turn, could be used to build new replicators, resulting in a kind
of positive feedback.
