So what makes intelligent symbiotic clusters different from
non-intelligent ones?  I'll aruge that Anthony's post in this thread has
some merit.  Straight lines, large-scale geometry (which nature seems to
abhor), and redistribution of certain chemistry (especially metals)
might have something to do with it.

Birds congregate by the tens of thousands during nesting, but they don't
great large-scale geometry.  They can and do modify the chemistry of the
environment (through their droppings, etc.) but the signature of a city
is significantly different than the signature of algae mats, bird
droppings, a buffalo herd's grazing range, etc.

Hallo

Reading through this thread, it comes to my mind:
 There was found these days in Melbourne (Australia) a structure of
about 10 km diameter, an underground building that can be named "City".
The inhabitans are ants from Argentinia. They have a difference in their
dna, which makes them not killing each other like in Argentinia.
 So, is this artifical or intelligece? When one of our robot creations
will do so, we will say so, hm? And what do we know about seti-signals
from ants? We even gues sometimes how they find their way home...
