I would also like to know the answer, Don knows it already (apparently)
but I don't think the rest of us do.
So, How do you "demonstrate" that a character is "derived"?
I would also like to know how does restricting the data matrix to
characters exclusive to the ingroup affect the outcome of the analysis,
and whether this introduces a bias or not. If I am not wrong the only
problem with characters shared between the ingroup and the outgroups is
that the polarity of this particular character would be equivocal, but
the character it self could be used for phylogenetic inference.
