Not really following this thread, but my eye was caught by "fractal bacteria
colony".
First off let me just say I'm a bit sceptical about calling this
"intelligence", but that's more a matter of the ongoing debate of what we
mean by the word "intelligence".
[Case]
I think the overall point I was trying to make is that whatever intelligence
is, it manifests itself in fairly continuous ways across species, beginning
with one celled organisms. This is not simply a matter of intellegence
evolving over time. It is here today.
[Ian]
That said, it may nevertheless be a clue as to how intelligence can arise.
We need to keep in mind he the distinction between Pirsig's "individual
amoeba" and the "bacteria colony" in this example ...
[Case]
The structure does not arise as a result of the organisms having a meeting
and deciding what to do. It is the result of each member responding to the
environment around it. As others get near and become part of the environment
they influence each other. Again this happens to each member of the colony
on a purely biochemical level. I believe there have been studies done on
similar phenomona involving the shapes taken by birds in flight and fish
schooling. These are examples of static patterns emerging dynamically and
chaotically from the natural environment. This can be seen to occur in a
purely mathematical way in the Game of Life:

The "information" to create the pattern must exist in the individuals, but
the explanation for creation of the pattern must lie in the interactions in
the whole colony. The pattern in the colony is on a different level to any
pattern of information in any individual. This is very close to Hofstadter's
Ant Colony (or population of China) explanation of potential consciousness.
Though with what looks like relatively immobile bacteria multiplying across
a 2 dimensional agar dish surface, there must be several orders less
interactions possible, than in an active 3D ant colony.
[Case]
Hmmm, not sure about that having the information of the whole pattern exist
in each individual. That would be more of a holographic representation. It
has been suggested that memory (temporal buffering) may work this way. I
suspect this is more primative than that and can be modeled with fairly
simple equations. While each individual is part of the pattern each member
would be interchangable with each other member. Their would be no
specialization as would be found in an ant colony. I am not familiar with
what Hofstadter had to say about ant colonies but I have read a bit of
Wilson and insects are his primary field of study.
