Okay, so this has a certain Scandanavian underworld flavor to it, but I'll
You are clearly confusing taxonomy (the issue of applying names to groups) to
cladistics/phylogenetic systematics (the analytical
practice of searching for the clustering pattern of taxa). The complications
and confusions that were specifically being dealt with
in the emails to which you were responding had very little to do with
cladistics proper, and far far more to do with taxonomic
And as someone schooled in both pre-cladistic and cladistic practices, I can
tell you that the issue of taxonomy prior to cladistics
was just as woolly-headed and mixed up (if not more so) than post-cladistics.
The majority of readers of this list have not read the
technical earlier taxonomic literature, but are more familiar with summary
works like Romer's or Carroll's textbooks.
However, as this mailing list has seen far more discussion of just these
particular subjects over the last decade plus, I don't see
much benefit rehasing them. I suggest most people interested in such a debate
review the archive (http://dml.cmnh.org) for these
topics. If after such a review they find that they have a novel argument, than
by all means post it!
