By cladistic point of view, I should have said a cladistic
point of view on higher level taxonomy... i.e., that only
monophyletic taxa deserve a formal name.  And by monphyletic, I mean
those that comprise ALL descendants (to avoid the monophyly holophyly
paraphyly business).  The ancestor of all protozoa is also an ancestor
of elephants.
