Obazoa (Brown et al., 2013) je predloženi sestrinski kladus Amoebozoa, sa kojim skupa čini grupu Amorphea. Obazoa obuhvata Breviatea, Apusomonadida i Opisthokonta, a posebno isključuje Amoebozoa. Utvrđivanje položaja Breviatea i Apusomonadida i njihovih svojstava od interesa je za poznavanje razvoja Opisthokonta, odakle potiču glavne loze životinja i gljiva.[1] Međuodnosi opisthokonata, brevijata i apusomonada nisu konačno riješeni (od 2018.), iako se obično zaključuje da, od tri loze, Breviatea najvjerovatnije mogu biti bazne.[2][3][4][5][6]

Sistematika

Filogenija na bazi ribosomne rRNK obično ne posmatra Obazoa kao kladus (vidi na primjer:[7]), koje vjerovatno odražavaju svojstva njihovog drevnog zajedničkog pretka, a malo filogenetskih signala ostaje u skupovima podataka od jednog ili nekoliko gena.

Filogenija

Filologenetičke analize obično Apusozoa i Opisthokonta postavljaju kao sestrinske kladuse, iako su, u drugim prilikama, Apusozoa oaraSlikatske, kako slijedi:[8]

 Obazoa

Breviatea

Apusomonadida

Opisthokonta

Globalno stablo eukariota iz konsenzusa filogenetskih dokaza (posebno, filogenomskih), rijetkih genomskih tragova i morfoloških karakteristika predstavljeno je prema Adl et al. 2012 i Burki 2014/2016 s Cryptophyta kriptofitima i pikozoama koji su se pojavili unutar grupe Archaeplastida.[9][10][11][12][13][14] Učinjeno je i slično uključivanje Glaucophyta, Cryptista (a također, neobično, Haptista).
