Figure 1: Phylogenetic relatedness of the three domains of life and of major phyla. Reprinted with permission from [9]. The Korarchaeota and Nanoarchaeota, as putative phyla, are shown via dotted lines. The Thaumarchaeota are not included, as they were previously grouped with the Crenarchaeota, and their independent phylogeny has not been unanimously agreed upon.
