Homochiral biology can be recognized as the outcome of an ancestral breaking of chiral symmetry which has subsequently propagated through a broadening range of descendant dynamic networks. Recently published research provisionally accounts for the establishment of biological homochirality by demonstrating that the chiral symmetry of ribo-aminooxazoline (RAO) in racemic solution is broken by exclusive adsorption of D-RAO, a precursor of RNA, on to a naturally-magnetized mineral surface (magnetite). This proposed mechanism in the prebiotic environment would allow for subsequent unidirectional propagation of homochirality through homochiral RNA to homochiral peptides (including enzymes) to homochiral metabolism. Noting these recent chemical and physical results, I show that an origin out of broken chiral symmetry and subsequent homochiral replication of the Byl cellular automata replicator (1989) can be seen as an analogy to the origin and propagation of biological homochirality.
