Final answer:
At the World Science Festival, biologist Edward O. Wilson discussed the advanced chemical "vocabulary" used by ants to communicate and organize within their colonies.
Step-by-step explanation:
Biologist Edward O. Wilson has been pivotal in researching and understanding the complex behaviors and communication methods of social insects. At the World Science Festival, Wilson discussed the intricate chemical "vocabulary" that these insects use. While bees and wasps, for instance, are known for their various forms of communication, it is ants that stand out in terms of their chemical communication sophistication according to Wilson's work. Ants utilize a range of pheromones and other chemicals to convey information, organize their labor, navigate to and from their colonies, and more.
