From the original Figures 3 and 4 only one has been kept and the legend rewritten. In fact, the whole paragraph changed to: “The newly proposed phylum Thaumarchaeota appears to be non-monophyletic as an outlying strain Candidatus Caldiarchaeum subterranum was assigned to this phylum according to the NCBI taxonomy. The NCBI assignment might reflect its position in some phylogenetic tree based on concatenated proteins, e.g., Figure 2 in […]. However, in the original paper reporting the discovery of this strain […] and in recent 16S rRNA studies, e.g., […], Candidatus Caldiarchaeum subterranum was proposed to make a new phylum Aigarchaeota. CVTrees support the introduction of this new phylum. A lineage modification of Candidatus Caldiarchaeum subterranum from Thaumarchaeota to Aigarchaeota would lead to a monophyletic Thaumarchaeota{7}.”
