Maybe we are agreeing since there may be a confusion between using the
term paraphyly, which I reject since there is an alternative:
macroevolution, and eliminating names because they cause other taxa to
be paraphyletic, which I also reject.
The discovery and documentation of biodiversity comes first ONLY if
nomenclatural changes associated with elimination of paraphyly are
rejected. It is scientific to retain apophyletic (= autophyletic, or
paraphyly causing) names, particularly when the names represent
macroevolutionarily important taxa, e.g. polar bears or Cactaceae. It is
also scientific to reject the whole concept of using sister-group
analysis alone to make classifications, which was what my analogic
parable was about.
I think I'm glad that I think we agree.

The discovery and documentation of biodiversity should ALWAYS come
don't care whether you label this taxonomy, or classify it as
science....what matters is that as populations of organisms disappear
they are currently doing at perhaps unprecedented rates), the vast, vast
majority of them will leave absolutely no trace of their existence.
burning the last copy of a book, whatever secrets they had to share
the "pages" of their genomes will be lost forever.
Hypothesizing relationships and speculating about theoretical
of inferred evolutionary processes are nice intellectual endeavors, but
should take a back seat to pure discovery and documentation.
