  7. Bacteria This icon shows the overall tree of life. The highlighted branch indicates which lineage is shown in more detail below Archaea EUKARYA Bacteria Archaea Paraphyletic group EUKARYA Fungi Animals All eukaryotes are protists (orange branches) except for the fungi, animals, and land plants Common ancestor of all eukaryotes Land plants
