The motions of the ants confirm the existence of a collective.
A colony is analogous to a brain where there are lots of neurons, each of which can only do something very simple, but together the whole brain can think. None of the neurons can think ant, but the brain can think ant, though nothing in the brain told that neuron to think ant.
For instance, ants scout for food in a precise pattern. What happens when that pattern no longer fits the circumstances, such as when Gordon moves the walls?
Ants communicate by chemicals, she said. Thats how they mostly perceive the world; they dont see very well. They use their antennae to smell. So to smell something, they have to get very close to it.
The best possible way for ants to find everything - if you think of the colony as an individual that is trying to do this - is to have an ant everywhere all the time, because if it doesnt happen close to an ant, theyre not going to know about it. Of course, there are not enough ants in the colony to do that, so somehow the ants have to move around in a pattern that allows them to cover space efficiently.
Keeping in mind that no one is in charge of a colony and that there is no central plan, how do the ants adjust their reconnaissance if their territory expands or shrinks?
No ant told them, OK, guys, if the arena is 20 by 20. . . . Somehow there has to be some rule that individual ants use in deciding to change the shape of their paths so they cover the areas effectively. I think that that rule is the rate in which they bump into each other.
