I listened to a fascinating episode on NPR’s TED Radio Hour a few months back, Why ants don’t need a leader. The interview with biologist Deborah Gordon fascinated me.
Picture this: the world’s largest ant colony stretches over 3,700 miles and it has been completely constructed by ants who self-organize through the interaction of individuals. And, as Deborah suggests, it succeeds because no one is in charge.
No blueprint. No leader. Just self-organization and collaboration.
Ants are capable of creating incredible structures out of nothing more than dirt; structures that in comparison would be as high as a skyscraper. Bridges which allow them to go on expeditions and water rafts to escape from flooding.
Ant colonies are illustrated as super organisms. A collection of organisms, which behave as one single organism. The ants work through collective intelligence, even though they are incapable of conscious organization.
It’s astonishing and incredibly inspiring to think that these teeny tiny insects with equally teeny tiny brains, are able to create such marvellous things.
Scientists have been studying the behaviour of ants for decades. They are some way towards understanding the rules that apply in the ant world in terms of survival, but they are still searching for clues as to how they coordinate behaviour, without the presence of a leader.
What is understood is that ants follow the formula of a complex decentralized system. Everything they do is based on the interaction of many individual ants, rather than having one leader who delegates tasks down the hierarchy. And they follow a few simple rules to make that system a success.
One of those rules is the need to interact at a local level. When ants are constructing, they interact with other ants on a local level. The ants who are collecting the dirt collaborate; those that are creating a pile of dirt work together, and those who are forming the structure, also stick together. The structures they are working on emerge without any central coordination. Their organizational skills are phenomenal.
I found a quote from a National Geographic article on Swarm Theory, which summarizes their incredible ability to self-organize:
No ant sees a big picture. No ant tells another ant what to do. The bottom line is that no leadership is required. Even complex behaviour may be coordinated by relatively simple interactions.
Although scientists are far from fully understanding how ants self-organize the way they do. And it’s still not conclusive as to why ants are so focused without leadership pressure. Organizations and manufacturers have been studying their scientific theories to see how the coordination behaviour of ants can be applied to workers and to manufacturing processes.
