Did he REALLY??  Man, I missed that!  And I find it hard to believe.   I
certainly consider polyphyletic taxa anathema, and can't believe Art
wouldn't have thought so, too.  Can you quote me chapter-and-verse on that?
I do recall him commenting on the idea of evolution across a broad front,
which I guess could be polyphyletic if broad enough.
