Again Grant, think of the imaginary line I brought up, of course single-
communicate, but that is not to say that this can 't be a second stage in
development into something more complex.
Single- cell floating around in an environment,
next step, two single- cells bumb into eachother, they got instinctive
next step, they try to communicate, trial and error,
next step, they speak to eachother
a step in evolution has been made.....

> THE NETWORKED BACTERIAL "BRAIN"
> Eshel Ben Jacob, at the University of Tel Aviv, and James Shapiro at the
> University of Chicago have been studying bacterial colonies from a
> original perspective - and have emerged with surprising results. Their
> findings explain why the ripple effect is a mark of bacterial networking -
> and of much, much more.
> For generations bacteria have been thought of as lone cells, each making
> own way in the world. Ben Jacob and Shapiro, on the other hand, have
> demonstrated that few, if any, bacteria are hermits. They are extremely
> social beasts. And undeveloped as their cellular structure might be, their
> social structure is a wonder. The ripple effect is one manifestation of a
> colony's coordinated tactics for mastering its environment. We could call
> the probe and feast approach.
> A bacterial spore lands on an area rich in food. Using the nutrients into
> which it has fallen, it reproduces at a dizzying rate. But eventually the
> initial food patch which gave it its start runs out. Stricken by famine,
> individual bacteria, which by now may number in the millions, do not, like
> the citizens of Athens during the plague of 430 b.c., die off where they
> lie. Instead these prokaryotes embark on a joint effort aimed at keeping
> colony alive.
> The initial progeny of the first spore were sedentary. Being rooted to one
> spot made sense when that microbit of territory was overflowing with
> edibles. Now the immobile form these first bacteria assumed is no longer a
> wise idea. Numerous cells switch gears. Rather than reproducing couch
> potatoes like themselves, they marshall their remaining resources to
> daughters of an entirely different kind - rambunctious rovers built for
> movement. Unlike their parents, members of the new generation sport an
> of external whips with which they can snake their way across a hard
> or twirl through water. This cohort departs en masse to seek its fortune,
> expanding ring-like from the base established by its ancestors. The
> of the fortunate lead to yet more food.

> generation of settlers accumulates in a thick band as it sucks nourishment
> from its locale. The ripples of ancient stromatolites are proof positive
> that life three and a half billion years ago already took advantage of
> social cooperation.
> The work of Ben Jacob and Shapiro has demonstrated that bacterial
> communities are elaborately interwoven by communication links. Their
> signalling devices are many: chemical outpourings with which one group
> transmits its findings to all in its vicinity; fragments of genetic
> material, each of which spreads a different story from one end of the
> population to another. And a variety of other devices for long-distance
> These turn a colony into a collective processor for sensing danger, for
> feeling out the environment, and for undergoing - if necessary - radical
> adaptations to survive and prosper, no matter how tough the challenge. The
> resulting modular learning machine is so ingenious that Eshel Ben Jacob
