More taxo-computational distractions

[Ami Scheltema]

          Some thoughts on some seeming windows on the past:
           Cyanobacteria--yes, indeed
           Limulus, the horshoe crab with a long fossil record
           Neopilina, the pseudometameric monoplacophoran mollusk--the
               Triblidiacea have also a long fossil record
           Aren't there some insects?
           Brachiopods

           If we consider the start of life on this planet: All
          characters are apomorphic at some level.  All characters are
          plesiomorphic at some level.

          The two terms are useful only in reference to the choice
          of outgroup (sister group).
