Some ant colonies consist of a queen, who performs all reproductive duties for the colony, and worker ants, who perform all the labor that the colony needs to gather food, expand and defend territory, and survive. The worker ants are also able to—but do not—contribute reproductively to the colony. In a colony like this, the worker ants will give their lives to defend the queen. Why is the worker ant considered altruistic?
