Were L ‐amino acids selected by living organisms because of their parity‐violating energy advantage? Despite the negligible magnitude of this energy, it has been frequently invoked that the excess of the more stable L ‐enantiomer might have been amplified during evolution. Two high level ab initio calculations have recently challenged this assumption.
