Current thought is that mitochondria were smaller lifeforms first “absorbed” by larger more complex cell (alternatively: the mitochondria “hijacked” the larger cell) and live in symbiosis.
Sounds weird, but also, we have more bacteria living in and on our bodies than we have cells with “our own” DNA.
Makes you wonder where we each really start and stop.

Just wait until you read about eyeballs.
