Dear All,
     I stand corrected on the biological definition of "polarization".  The
"Mr. Spock" in me still thinks it is illogical that the term "ordering" was
restricted only to cases where you have 3 or more character states.  But
usage is what counts, so I will not belabor it further.            :-)

P.S.  However, if we are going to be precise, it is even more important that
we should oppose the usage of the term "monophyly" as it has been
cladistically redefined.  That was so illogical, that Ashlock had to propose
the term "holophyly" (in 1971) to remedy the situation (which was
unfortunately resisted).  I highly recommend the usage of the term
holophyletic, even though most people say "monophyletic".  Or at the very
least, say "strictly monophyletic" when you mean holophyletic.
