Obazoa (Brown, 2013) is a proposed sister clade of Amoebozoa (which combined form Amorphea). Obazoa is composed of Breviata, Apusomonadida and Opisthokonta, and specifically excludes the Amoebozoa. Determining the placement of Breviata and Apusomonadida and their properties is of interest for the development of the Opisthokonts in which the main lineages of Animals and Fungi emerged.[1] While originally Breviata was seen as more basal than Apusomonadida, Breviata and Apusomonadida are found to be direct sisters (with 100% bootstrap support), forming a basal clade Apusozoa as sister of the Opisthokonta.[2][3][4][5] In some recent research, Obazoa is not seen as a clade.[6]
