A phylogenetic analysis based upon ribosomal RNA sequence characterization reveals that
living systems represent one of three aboriginal lines of descent:(i) the eubacteria,
comprising all typical bacteria;(ii) the archaebacteria, containing methanogenic bacteria;
and (iii) the urkaryotes, now represented in the cytoplasmic component of eukaryotic cells.
