　　Collective intelligence: Ants and brains neurons

　　STANFORD - An individual ant is not very bright, but ants in a colony, operating as a collective, do remarkable things.

　　A single neuron in the human brain can respond only to what the neurons connected to it are doing, but all of them together can be Immanuel Kant.

　　For instance, an ant may have several job descriptions. When the colony discovers a new source of food, an ant doing housekeeping duty may suddenly become a forager. Or if the colonys territory size expands or contracts, patroller ants change the shape of their reconnaissance pattern to conform to the new realities.
