  That's a MAD theory =). Wow.
  It's a pity even multicellular organisms were pretty
 rare about the time the CO2 levels dropped. Still...
 we *could* try to make the facts fit the theory if
 we make up some more mad stuff to explain everything
  (Brains could have evolved as a cushioning pad to 
 prevent damage when you are dropped on your head...
 which as everyone knows is not good for you at all.
 And this is the reason humans (who walk upright and
 have a long way to fall) have such big brains)
 "And I know I was wrong when I said it was
true that it could have been me or been her
inbetween without you."
