Hypotheses on the origin of life on Earth are discussed in the frame of alternative ideas concerning processes of abiogenesis, formation of protometabolic systems, beginnings of initial protocells. Arguments in favor of independent origin of archaea and bacteria are considered. Based on this information, a new view on the problem of life’s origin is presented. As supposed, life might have aroused multiple times and asynchronously in various local geochemical conditions dependent on many natural factors.
