The evolutionary relationship within prokaryotes is examined based on signature sequences (defined as conserved inserts or deletions shared by specific taxa) and phylogenies derived from different proteins. Archaebacteria are indicated as being monophyletic by a number of proteins related to the information transfer processes. In contrast, for several other highly conserved proteins, common signature sequences are present in archaebacteria and Gram‐positive bacteria, whereas Gram‐negative bacteria are indicated as being distinct. For these proteins, archaebacteria do not form a phylogenetically distinct clade but show polyphyletic branching within Gram‐positive bacteria. A closer relationship of archaebacteria to Gram‐positive bacteria in comparison with Gram‐negative bacteria is generally seen for the majority of the available gene/protein sequences. To account for these results and the fact that both archaebacteria and Gram‐positive bacteria are prokaryotes surrounded by a single cell membrane, I propose that the primary division within prokaryotes is between monoderm prokaryotes (surrounded by a single membrane) and diderm prokaryotes (i.e. all true Gram‐negative bacteria contai
