Abstract
The single handedness of biological molecules has fascinated scientists and laymen alike since Pasteur's first painstaking separation of the enantiomorphic crystals of a tartrate salt over 150 years ago. More recently, a number of theoretical and experimental investigations have helped to delineate models for how one enantiomer might have come to dominate over the other from what presumably was a racemic prebiotic world. Mechanisms for enantioenrichment that include either chemical or physical processes, or a combination of both, are discussed in the context of experimental studies in autocatalysis and in the phase behaviour of chiral molecules.
