Hi John et al.,

Excluding the autapomorphies doesn't change the tree topology anyway
(since they always map on to the terminal branches).  You do this in
PAUP just so the consistency index is calculated without them -
otherwise the consistency index is inflated by characters that played
no part in the calculation of the most parsimonious tree.

Cheers, David.
