So-called chiral breaking problem on biological amino acids has intrigued many scientists for hundreds of years, but there has been no general consensus as yet. Racemization pressure is overwhelmingly powerful even in contemporary homochiral biological environment, not to speak of early global environment. It was essential for birth of life to escape from racemic world. Life could not say goodbye to non-life forever until a mechanism of enantioselectivity, which made exclusive choice of enantiomeric type, was established in an automated way by abiotic process. Author proposes it should be a basic principle that separates life from non-life.
