Proposed group of single-celled organisms
Obazoa is a proposed sister
clade of
Amoebozoa (which together form
Amorphea ). The term Obazoa is based on the OBA
acronym for
O pisthokonta ,
B reviatea , and
A pusomonadida , 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.

The phylogeny of the Obazoa is shown in the cladogram.
