Why this is here
A1 said the eukaryogenesis papers “help discriminate between explanations based on metabolic syntrophy, cellular complexity preceding mitochondrial acquisition, and integration following endosymbiosis”, and cited none of the explanations. This is the classic syntrophy explanation, a mitochondrion-early scenario that rests on metabolic dependence.
