title: Elementary asymmetry and biochirality: no longer twinned.
abstract: 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.
