Bacteria “R” Us
There is a domain of creatures that diffusively encircles an entire planet. There are so many of them that they occupy every conceivable ecological niche. Yet, despite their countless numbers they are so in tune with their local ecology that they have become an intrinsic part of it. Those that live in rural locations greatly outnumber those that inhabit strange cites, which are gregarious, smart and even have their own personalities. The cities consider themselves as being independent from their inhabitants, yet share their nutrition with them. They have a diurnal waste cycle that removes debris and also makes room for a new influx of city dwellers. Mature cities can even reproduce to make new ones that are immediately available for the city inhabitants to colonize.
Modern biotechnology has recently revealed that humans are immersed in a bacterial world. So much so, that an alien naturalist might consider humans as little more than smart city housing for bacterial colonies. While we think we are at the top of an evolutionary tree, it appears that our evolution is closely linked to, if not entirely dependent on bacteria. They have collectively made it possible for complex life forms to exist as they have produced our breathable atmosphere, our soil and even our rainfall. Although they have not been proven to possess a collective ‘mind’ they do have extremely sophisticated methods of communicating using linguistic qualities . They encircle the planet like a chemical Internet and hold incessant conversations using physics and chemistry.
