evolutionary stages under discussion are : the self-organization of spontaneously formed biomolecules into early precursors of life ( protobionts ) , their stepwise evolution via ( postulated ) protocells to ( postulated ) progenotes and the darwinian evolution from progenotes to the three kingdoms of contemporary organisms ( archaebacteria , eubacteria and eukaryotes ) .
