For characters that exhibit no homoplasy, this is logically identical to
the methods outlined so clearly in the ancient papers that many of us
have fruitlessly cited. When homoplasy exists, it is a far inferior
method, since it must either fail outright or else rely on a method
other than parsiimony to decide each case.

Perhaps the absence of challenge to these papers in the ensuing two
decades is a result of inattention to their failings, and perhaps you
will now explain to us carefully point-for-point how they are wrong, but
I suspect instead that you are so fixated on the orangutan hypothesis
that you would even challenge panbiogeography, if necessary, to support it.
