List of 94 species.

List of the 94 species distributed across the tree-of-life studied in the large-scale analysis and their taxonomic identities, Eukaryotes (1–39) and Prokaryotes (49–94). The ordering of species is according to the tree-of life [47]. Within Eukaryotes, kingdoms are first ordered from Animalia to Plantae (P) to Fungi (F). Animalia are classified as vertebrates (V), and invertebrates (IV). Within each kingdom ordering is according the phylogenetic distance from the first species, i.e. Human within Animalia, A. thaliana within Plantae and Nectria within Fungi. Protista (PRT) are added at the end with no phylogenetic analysis. Bacteria are also ordered according to the Phylum as presented in [47], where within each Phylum the ordering is according to DFT counts. Archaea are ordered by DFT counts. Mesophiles (M) and Thremophiles (T) are indicated.
