Obazoa is a proposed sisterclade ofAmoebozoa (which together formAmorphea ). The term Obazoa is based on the OBAacronym forO pisthokontaB reviateaA pusomonadidaeclades .[ 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 ofanimals andfungi emerged.[ 1] [ 2] [ 3] [ 4] [ 5] [ 6]
The phylogeny of the Obazoa is shown in the cladogram.[ 6] [ 7] [ 8] [ 9]
