There is no such thing as a cladistic classification. Cladistics is a method
(and a fallible one, at that) for determining relationships between
organisms. Many cladists in practice use phylogenetic taxonomy, in which
clades are defined by their common descent with or relative proximity to
particular "anchor taxa".
I have some very serious reservations about using rigid phylogenetic
taxonomy, as in many cases we are uncertain enough of the relationships in
question as to make the composition of these phylogenetically-defined groups
On the other hand, I (and I am strictly a non-professional, a graduate
student in another field of inquiry) do insist that my classificatory groups
