Later Woesearchaeota and Pacearchaeota were discovered and proposed within the DPANN superphylum. DPANN is a superphylum of Archaea first proposed in 2013. Mien, to form an East Asian superphylum. The broadest definition proposes the monophyletic superphylum Lobopodia is equivalent to Panarthropoda. This hypothesis groups annelids with molluscs and brachiopods in another superphylum, Lophotrochozoa. Another proposal is to group Discicristata with Jakobida into Discoba superphylum. The Asgard superphylum represents the closest prokaryotic relatives of eukaryotes. More recent research has established the Lophotrochozoa as a superphylum within the Metazoa. Proteobacteria may be phyla in their own right, which would make Proteobacteria a superphylum. Earlier work proposed that many phyla under the CPR group form a superphylum called Patescibacteria. The asgard archaea superphylum is composed of Thorarchaeota, Lokiarchaeota, Odinarchaeota, and Heimdallarchaeota. "P. marinus" is a protozoan of the protist superphylum Alveolata, the alveolates. In 2017, another phylum Altiarchaeota was placed into this superphylum. The Chordata and Ambulacraria together form the superphylum Deuterostomia. Deuterostomes form a superphylum of animals and are the sister clade of the protostomes.
