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.[2] [3] [4] [5] [6]
The phylogeny of the Obazoa is shown in the cladogram.[7] [8] [9] [10]
