Subject: [alt-beam] Re: Chaotic controllers (was Something funny with the 1382)


this seems pretty cool, I wonder if you took a colony of anys, and put
them in a very basic RJP and put a food trough at one and and a shelter at
the other, taking away most of the work the ants need to do to survive, if
the ants would start to evolve over a couple years. i wonder what it would
turn out like. say maybe if thier brains got bored so they started to
invent thier own entertainment? or if you put more than one colony you
could get trade agreements, then currency, then government to take it away
again =3D^) that would be cool. especially if you could survive long enough
too see it evolve.

OK, thats just a little too wierd, maybe cause it's 2:30 AM.
good night,

PS. at the bottom of the page I have included a little humor to lighten up
this flame war. hope you dont mind.
