Submission + - Tracking whole colonies shows ants make career moves (nature.com)

The biologists have found that the workers fall into three social groups that perform different roles: nursing the queen and young; cleaning the colony; and foraging for food. The insects, they found, tend to graduate from one group to another as they age.
