Thank you. You're right of course, I was being sloppy here. It is
truly unique character states that are "safe" in terms of not mucking
up the resolution an analysis; but a characters that is autapomorphic
below one node may also well by autapomorphic below and second (and
synapomophic on a third).

Baseball -- the definitive, unsinkable counter-argument to anyone who
claims that Americans are slipping behind the rest of the world. And
country whose kids can understand it is worthy of great respect.
(That said, I would still argue that cricket is superior as it's the
only game whose laws include rules about tea-breaks.)
