Keep in mind that some reviewers (and journal editors) are now strongly
pressuring authors to at least do lip service to phylogenetics when a new
taxon is described. Pressure is even put on paleontologists who do not
"specialize" in the subject. The result is, for the sake of expediency
in getting the new animal to press, a less than complete cladogram.
The solution to this problem? Stop pressuring those who's specialty is
something other than cladistics to include cladistic phylogenies in their
papers.
