Fig. 1From: Tracing the evolution of the heterotrimeric G protein α subunit in MetazoaAll phylogenetic branches investigated. 45 species of Deuterostomia were evaluated through the EMS pipeline. The Latin names and clades for each species are provided. The outgroups include two Protostomia species, four non-Bilatera Metazoa, two Non-Metazoa Holozoa and one Fungi. Protostomia and Deuterostomia together form the group of Bilateria. Echinodermata and Hemichordata form the group of AmbulacrariaBack to article page
