Why was finding a close relationship between mitochondrial DNADNA and bacterial DNADNA considered particularly strong evidence in favor of the endosymbiosis theory?

Endosymbionts Co-Evolution...

Explanation:

This is the only main evidence because let say we observe the size of mitochondrial DNA to be 70S and we measure the same for bacteria to be 70S. This means that there was some kind of endosymbiont relationship in ancient past or at origin of complex multi-cellular organisms that caused co-evolution of both of these and it;'s just not a mere coincidence...
