Your response has been roughly "well, the DNA is related, ergo they have only one (or few) common ancestors."

No no no!

I said if the DNA between all oragnisms differed, then it would falsify common descent. I did not set out to prove common descent, only to establish a criterion to falsify it. Do you not see the difference?

You assert it is safe to assume that.

Yes, and then I provided you evidence for my assertions. Not "proof" mind you, but evidence. And I have plenty more where that one example came from.

Yes. Of course, that criterion doesn't falsify ID or the alien zoo dump, either.
