I suppose it depends on which model you use, and as discussed they seem to vary and be in flux right now, but the three domain model I learned was prokaryotes, archaea, and eukaryotes - the first two being different domains.

I wasn't trying to refute it; I was adding information: The quote didn't mention or imply that there are also single-cell eukaryotes, so I added that detail.

We agree. I don't grasp your point?
