Not exactly sure I can go along with the idea that the primary loci of these little critters is the mitochondria but there you have it.
Well, so much for the primacy of the nuclei!
Using scientific principles in studying the origin of life, one can only conclude that it was intelligently designed. To deny that fact is to be irrational.
