When a queen is removed from a jumping ant hive, for example, the worker ants "launch a vicious, fight-to-the-death campaign against one another -stinging, biting, sparring, lopping off limbs and heads"- until a few workers win and become, well, monarchical. Without any alteration in DNA structure, the physiology of a new queen changes; "she" now becomes fecund and dominant and will live longer than she would have in her previous worker incarnation.
