(5 points, 1 point each) Have you ever looked at an ant and 1 how such a small creature was able to do so much? Ants travel long distances, build huge structures to live in, and sometimes even catch much larger animals to eat. For such a tiny insect, they seem quite 2 . But according to scientists, individual ants aren’t smart; ant colonies are. A group of ants can solve problems individual ants can’t, such as finding food quickly or protecting their home from other insects. In a colony, no single ant knows what’s best for the group, and though there is a queen, her only role is to lay eggs; there is no group 3 telling the others what to do. How is it possible, then, for the colony to get anything done? According to scientists who study ants, the colony’s success is a result of self-organizing—each ant looking 4 , seeing what has to be done, and then doing its part. Perhaps this is finding food, or caring for the 5 , or many other tasks. Each ant has no idea that many others are doing the same thing at the same time to help the group, but it doesn’t matter because the work gets done. And there’s a lot, say scientists, that humans can learn from this kind of behavior.
