What about those recently discovered dinosaurs with feathers and no wings?
And what if morganucodonts were still around? Would we put them *in*
Mammalia or take the monotremes out?
It's strange how so many of our paraphyletic groups either reflect
ignorance-because-of-not-paying-attention. Willfully using ignorance as a
separation criterion for taxa strikes me as somewhat unscientific.
