NON-TRIVIAL REPLICATORS. “Although modern life is clearly representative of the class of non-trivial self-replicators, the majority of work on the origin of life has focused on the conceptually simpler case of trivial self-replication. This is not without good reason: the origin of translation—mediating what is known of the transition from trivial to non-trivial—is notoriously difficult to pin down, amounting to an algorithmic takeover of information stored in one molecular species (nucleic acids) that becomes operable over another structurally and chemically very different species (peptides).”
