ABSTRACT The present review summarizes concentrated discussions regarding the most important new results of research aimed at understanding the origins of biological chirality. After discussing the key model reaction named as asymmetric autocatalysis (Soai reaction) in Part I, here the most important aspects of possible extraterrestrial origin of biological chirality are summarized. The most decisive results in this direction have been achieved by chemical analyses of meteorite samples as well as by photochemical model reactions.
