Comparative cataloging of the 16S rRNA ofHalobacterium halobium indicates that the organism did not arise, as a halophilic adaptation, from some typical bacterium. Rather,H. halobium is a member of the Archaebacteria, an ancient group of organisms that are no more related to typical bacteria than they are to eucaryotes.
