Bacteria don't have mitochondria!
We are talking about comparison between cytochrome C amino acid and nucleotide sequences in eukaryotes not eukaryotes and prokaryotes..
Bacteria don’t have mitochondria? So what? Who said that they did?
They are living things and have Cytochrome C. That makes them revelant here.
On another thread you wrote: “Every living thing descended from a common ancestor over millions of years. This is the central fact that the theory of evolution explains.”
Obviously that includes bacteria. So they are relevant to this discussion.
As a matter of fact evolutionists claim (or have anyway) that everything else descended from bacteria (that includes eukaryotes).
Your whole ‘objection’ here is illustrative that you are the type of poster that tries to ‘challenge’ everything.
