Come and Get Me

Self-sacrifice for the good of others has long been associated with certain religious doctrines.  People who exemplify such teachings are often heralded as the best that humanity has to offer.

Yet these heroes may be no match for the average ant.  Consider this: When a young ant catches an infection that could threaten the rest of the colony, it emits a chemical signal that essentially says, “Come and get me!”

Worker ants then come and do exactly that.  They proceed to “bite holes in the pupae and inject poison,” thus killing the ailing ant and disinfecting the nest.  Erika Dawson of Austria’s Institute of Science and Technology explained “that the sick pupae only produce the smell when worker ants are nearby, proving it is a deliberate signal for destruction.”  She therefore called this “an altruistic act.”
