Cheater Ants

Thursday, January 22, 2009

In ant society, workers give up reproducing in order to care for the queen’s offspring. When the workers cheat and try to have their own kids, their fellow workers attack them in order to stop them from reproducing. Dr. Juergen Liebig of Arizona State University, author of a new study in Current Biology, explains how cheating ants produce a chemical that is a dead giveaway to their peers.
