     Ants have an amazing ability to communicate with each other and work together to accomplish(完成)

difficult tasks.Their specialized behavior due to chemical communication is so well developed, in fact, that

humans can learn a lot from them about how to work best in teams.

      British scientists at the University of Bristol are studying colonies(群体)of army ants to understand

how they organize themselves and share knowledge.These insects-which come in various sizes-are known for using their bodies as living plugs to cover holes on the uneven ground between their nest and their prey.When they meet a hole in their path, they can quickly determine which of them is the best fit.The

appropriate ant then lies across the gap, allowing the remainder of the group-as many as 200,000 other

ants-to step on its back.This important minority of ants makes the food collection of the entire colony in

the best possible way by "paving the way" for the others.

     The collective behavior that emerges from a group of social insects, such as ants, can be called

"swarm intelligence". Swarm intelligence consists of the selforganization of many individuals that work

collectively to find the best solution to a difficult problem.The concepts of swarm intelligence have been

used in a variety of human applications.It has been used as a method that improves the efficiency of

goods transfers on airplanes, and has even become a routing technique for moving data across

telecommunications networks more smoothly.You could say that our daily lives benefit from the tireless

work of ants.
