Phylogenetic structure of the prokaryotic domain: the primary kingdoms

C R Woese et al. Proc Natl Acad Sci U S A. 1977 Nov.

Abstract

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.
