An idea that was shockingly revolutionary as recently as the early nineties--but is now almost universally accepted--is that mitochondria are descendants of bacteria (procaryotes)--that the discovery of the advantages of keeping computer disks and coal is separate compartments involved a large simple cell (which was perhaps energetically inefficient) getting invaded by a smaller bacteria (which was energetically more efficient).

The arrival of eucaryotes looks more progressive than it really was because of the failure to depict the persisting hordes of procaryotes. The same false impression is conveyed with each new arrival on the stage: vertebrates, large-brained animals, and so on.
Bacteria, together with cyanobacteria (blue-green algae), are single-celled lower protista known as procaryotes. Procaryotic cells do not have a true nucleus, the bacteria's DNA being present as a single molecule in the cell's interior.
