Mitochondria are ATP-generating organelles, the endosymbiotic origin of which was a key event in the evolution of eukaryotic cells. Despite strong phylogenetic evidence that mitochondria had an alphaproteobacterial ancestry, efforts to pinpoint their closest relatives among sampled alphaproteobacteria have generated conflicting results, complicating detailed inferences about the identity and nature of the mitochondrial ancestor.

 previous hypotheses on the nature of the mitochondrial ancestor should be re-evaluated.

ATP?   Huh?
