The prebiotic emergence of molecules capable both of self‐replication and of storing information was a defining event at the dawn of life. Still, no plausible prebiotic self‐replication of biologically relevant molecules has been demonstrated. Building upon the known templating nature of amyloids, we present two systems in which the products of a peptide‐bond‐forming reaction act as self‐replicators...
Simple amino acids activated by the volcanic gas carbonyl sulfide can condense into peptides that then spontaneously assemble into amyloids. This suggests a plausible prebiotic relevance of peptide amyloids and has led to the discovery that they can template sequence‐selective, regioselective and stereoselective peptide synthesis. Depending on the environmental conditions, such amyloid templating...
