That seems impossible................
Agreed... I wish when statements like this are made, they are followed by some real data to support the hypothesis.
If every cell has mitochondria, and mitochondria supposedly have separate and different dna than what is in the cell nucleus, then it seems to me all these things with separate dna are way more numerous than actual human cells. I think there is a theory that says mitochondria were actually some sort of invading bacteria at one time or something. But I am for sure no expert.

Bacterium are really small.
