Anaeromonadea Explained

Anaeromonadea, also known as Preaxostyla,^[1] is a class of excavate protists, comprising the oxymonads, Trimastix,^[2] and Paratrimastix. This group is studied as a model system for reductive evolution of mitochondria,^[3] because it includes both organisms with anaerobic mitochondrion-like organelles (Trimastix^[4] and Paratrimastix^[5]), and those that have completely lost their mitochondria (oxymonads Monocercomonoides,^[6] Streblomastix, and Blattamonas).
