Metakaryota

The superkingdom Metakaryota was defined by Thomas Cavalier-Smith as advanced eukaryotes resulting from the endosymbiosis of a proteobacterium, giving rise to the mitochondrion, by an archezoan eukaryote. However, with the collapse of the Archezoa hypothesis (that amitochondriate eukaryotes were basal), this grouping was abandoned in later schemes.[2][3]
