archaeon

(är′kē-ŏn′)
n. pl. ar·chaea (-kē-ə)
Any of various prokaryotic microorganisms of the domain Archaea, being genetically distinct from bacteria and often living in habitats with extreme environmental conditions such as high temperature or salinity. Also called archaebacterium.

Downdrift change is accelerated beyond anything the Archaeon's long memory has seen before, leading the organism to posit that it's not genetic mutation but a cultural phenomenon that's transferred socially.
In addition, the abundant proteins matched to ROS scavengers like superoxide dismutase (L0KZ58) and catalase (L0L0M1) of Methanomethylovorans, as that archaeon may be under oxidative stress in the reactor loaded with QMA.

At present, the most widely accepted theory is that mitochondria derive from a bacterium that was engulfed by an archaeon (plural = archaea), a kind of prokaryote that looks similar to a bacterium but has many molecular differences.
The catalase and superoxide dismutase genes are transcriptionally up-regulated upon oxidative stress in the strictly anaerobic archaeon Methanosarcina barkeri.
