One can code polymorphisms. :-) This lets PAUP* sort out which of the 2 or
more states is plesiomorphic within the group, as if its species were coded
separately, but still keeps the matrix small.

Eh, but there's no possibility to tell _what_'s wrong. Because that could be
the sampling of the fossil record. It doesn't have to be the coding.
(Extreme example -- put *Alexornis* in any matrix of basal birds, and it'll
come out in a polytomy, because it consists mostly of missing data.)
