The seeming incongruity is caused by the diversity of Zn fingers, or the small cysteine-rich Zn binding protein
folds.  There are 28 "fold superfamilies" that are small cysteine-rich Zn binding proteins and 76 protein families nested within that.   Most of these evolved very late and most are only found in eukaryotes.  But it looks like there are a select few zinc fingers and beta ribbons that evolved very early and are found in all bacteria and archaea as well.
