Phylogenetic tree of life based on small-subunit ribosomal RNA sequences, showing representative species from each of the three kingdoms (compiled by Pace [11]).

The root of the tree is indicated by a horizontal line. The locations on the tree of Halomonas sp. (GFAJ-1) [2] and Mycoplasma mycoides (JCVI-syn1.0) [3] are indicated by black circles adjacent to Escherichia and Bacillus, respectively.
