Karnkowska et al. (2019), LIT-1574, read in full in NOTE-1243. The paper argues that the functions were removed in turn, the SUF replacement shared across Preaxostyla and the glycine cleavage loss after the split from Paratrimastix, before the organelle went.
Where the evidence stands
What the paper shows, and what it does not, is THEORY-1098, Active, which this entry extends: that entry is the reading, this one the thesis. The promote_when above is THEORY-1098’s condition before the twenty-second status review promoted it, carried here unchanged, because it asks what would make the thesis true and not what the paper says.
