Superorganisms are hives of organisms that work together to function as a whole. The most notable cases are ants and bees, but other organisms work together as superorganisms as well. Superorganisms are fascinating due to the emergent intelligence that arises from the sum of unintelligent parts. We would not call one ant intelligent, yet a hive functioning together can complete remarkable feats, such as building a bridge or creating a complex social hierarchy.
The world of humans is moving towards a global superorganism. Telecommunications, cell phones and highway systems allow information to go from one side of the world to the other at the speed of light.
