From what Google found it looks like you wrote the second to the last paragraph, not copy/past from something you found online.


Well of course I wrote it!  Only dumbfucks copy and paste from Wiki and call it "information" or an "argument" or a "rebuttal."  I sourced my information through my subscriptions to the NIH archives and I got some dates from Ancestry.com with some help from friends I have at that company.  Ya see, Gary baby, it's contacts and resources that distinguishes a Real Scientist ™ like me from a miserable dog like you.

Anyway, your model sucks pond water mainly because you haven't even attempted to add any environmental feedback loops which looks simple enough to me to do.  No organism evolves as an island unto itself.  (The Archipelago Principle of Biogeography - look it up.)

Case in point is research done by S. Baldwin, J. Xu and Cleveland Tyler (NIH Letters, 2006, 2012) on the "Symbiotic Communication in the Distribution of Pinus taeda (Loblolly Pine) in an Extended Rhizome Field."  The trees in question are known as the "Lost Pines" of central Texas because they are genetically nearly identical to loblolly pines that grow in east Texas, Louisiana, Oklahoma and Arkansas.  The "Lost Pines" near Bastrop, Texas are curious because they have had no obvious connection to the separated population for thousands and possibly hundreds of thousands of years.  Baldwin and Xu, however, document a symbiotic relationship with a mushroom rhizome common to south Texas much like the Armillaria ostoyae (honey mushroom) of Oregon that can grow to be hundreds of miles long subterraneanly.  These rhizomes form some of the largest organisms on the planet although a handful of individual rhizome fibers weigh only a few grams.

The rhizomes in question only inhabit loblolly pine forests although this particular rhizome has been traced from the Hill Country of Texas through the San Jacinto river basin and down to southeast Texas where it joins up with the main body.  Following the devastating fires in the Bastrop region a couple of years ago, the researchers noticed a huge increase in rhizome activity not only in the fire affected area but in the eastern pine forests, too, as if the regions stress was being felt or communicated several hundred miles away.

Coincidentally, or not, the eastern pines have dropped an inordinate  amount of seeds this year, as have the live oak trees with acorns - well documented - and these seeds are being carried to the fire-affected area by migrating grackles who flock in this region every year.

Why the increased rhizome activity hundreds of miles apart?  Why increased seed production?  Why have loblolly pines in the Bastrop forest recovered faster than other plant species?  Baldwin and Xu do not propose a mechanism but their research shows a high positive correlation with a 95% confidence interval that an undocumented interspecies symbiosis is occurring not only between species but between phyla.  I'll download a copy of this paper and, copyright restrictions permitting, will make it available.

But, for your model, you'll need to extend it to multiple bots with interacting parameters and feedback loops, positive and negative, that you can tinker with to simulate stress and reaction.  My thoughts.
