Taxonomic distribution of research articles and sequenced genomes. Modern taxonomy identifies five major eukaryotic supergroups: the Excavates (turquoise), Chromalveolates (orange), Archaeplastida (green), Amoebozoa (purple), and Opisthokonts (red). Although the total number of species on earth remains unknown, it is clear that there are far more unicellular eukaryotes than the combined total of all animals (Metazoa, an Opisthokont lineage), fungi (also Opisthokonts), and plants (Archaeplastida). However, research activity displays considerable taxonomic bias. As of January 2014, the National Center for Biotechnology Information taxonomy browser (www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi) lists 338 Archaeal genomes (dark gray), 20,709 Eubacteria (light gray), 769 Metazoa, 1,201 Fungi, 251 green plants/algae, and 336 genomes from all other eukaryotic taxa (13% of eukaryotic genomes). The taxonomic distribution of PubMed citations is as follows: Archaea, 19,000; Eubacteria, 397,000; Metazoa, 576,000; Fungi, 135,000; green plants/algae, 168,000; and all other eukaryotes combined, 97,000 (<9% of publications on Eukaryotes).
