Good point... may not it be assessed, however, for similarly sized
matrices? I mean, if you deal with a mostly common matrix as that of
the Theropod Working Group. Alternatively, the CI may be useful to
compare phylogenies with ever increasing size, and helping with a
larger database for future studies on homoplasy (if publication space
is not a problem).
