I found myself trying to tease out what exactly you mean by complexity,
which I've found is where most conversations of this sort go awry.  "More
complex =~ larger" is loosely implied here, as is "more complex =~ more
differentiable cell types" and as also is "more complex =~ more
interactions".  Rather than wager more likely misguided guesses, I figured
I'd ask you if you could espouse a bit on your question.
(This of course is the penultimate problem, well at least IMO.  Complexity
is about an umbrella a term as I can think of, and each of these implied
meanings I've guessed at above has an entire school of evolutionary
thinking).
