Hi Curtis:
       Eubacteria were first to split off in the tree of life.
Cavalier-Smith has gone as far as arguing that Metabacteria
(Archaebacteria) probably arose less than a billion years ago.  I think
that age is too young, but I still believe Eubacteria arose much earlier
than Metabacteria.            
       As for the prefix meta-, I believe it has a lot of different
meanings.  "The New Oxford American Dictionary" lists one meaning as
"denoting something of a higher or second-order kind."  So I don't think
"higher" is such a stretch.                   
      --------Ken Kinman              
P.S.   Point well taken about respiration and plants.  So forget what I
said about mitochondria and respiration.  I clearly didn't think that
one through, and sometimes rattle on when I would be better off keeping
it short and sweet.  My bad.

    To be precise, ???? followed by the genitive means "among",
"between", or "with", and followed by the accusative means "after" or
"afterwards". "Higher" is a real stretch.
