A Phylogenomic Census of Molecular Functions Identifies Modern Thermophilic Archaea as the Most Ancient Form of Cellular Life
Figure 5
The tripartite division of the cellular world. (a) A ToL (tree length = 87,892) generated from the genomic census of GOTMF terms in 249 free-living genomes resolves the three primary superkingdoms. Archaeal species (red) occupy the most basal positions in a paraphyletic manner, while monophyletic Bacteria (blue) and Eukarya (green) are evolutionarily derived. Numbers on branches indicate bootstrap support values. (b) A 3D-scatter plot dissects organisms into three superkingdoms: Archaea, Bacteria, and Eukarya. Genomes are labeled as in (a).
