        Umm... lemme make this a bit more clear:
        More or less inclusive *clades* necessarily have equal status as
entities, because they are recognized on the same principles. A paraphyletic
group and a monophlyetic group do not have equal status simply because they
are subsets of the content of a clade. They must derive their status
independant of that association by some inherent property, else they are a
mental construct rather than a real entity.
