Ant colonies that are highly specialized have lower chances of survival when sudden changes occur

A characteristic of insect societies such as ants is the way tasks are distributed among group members. Not only queens and worker ants have clearly defined responsibilities but the workers themselves also have particular jobs to do when, for example, it comes to the care of the young, defense, and nest building activities. It is widely assumed that this division of labor is an essential factor that determines the success of such social groups. According to this view, a high degree of specialization provides advantages because the individual tasks are performed better and more effectively. It seems, however, that this advantage may actually be a great disadvantage in special circumstances. As researchers have discovered, highly specialized ants lack the flexibility to adapt to new situations — with serious consequences for the entire colony. —> Read More
