Obazoa is a proposed sister

Apusomonadida, the group's three constituent clades.[1]

Determining the placement of Breviatea 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] The relationships among opisthokonts, breviates and apusomonads are not conclusively resolved (as of 2018), though Breviatea is usually inferred to be the most basal of the three lineages.[2][3][4][5][6]

The phylogeny of the Obazoa is shown in the cladogram.[6][7][8][9]
