Figure 4

Inferred ancestral genomes in Archaea. The square boxes at the bases of clades indicate the number of families in the inferred ancestral genomes; the rectangles at the tips of clades indicate the number of families in the extant genomes within the clade. Square boxes at the tips indicate single genomes; rectangular boxes indicate multiple genomes.
