-----Mensagem original----- Assunto: [gl-L] Cockroaches Make Group Decisions By Jennifer Viegas, Discovery News March 30, 2006 Cockroaches govern themselves in a very simple democracy where each insect has equal standing and group consultations precede decisions that affect the entire group, indicates a new study. The research determined that cockroach decision-making follows a predictable pattern that could explain group dynamics of other insects and animals, such as ants, spiders, fish and even cows. Cockroaches, Blattella germanica, are silent creatures, save perhaps for the sound of them scurrying over a countertop. They therefore must communicate without vocalizing. "Cockroaches use chemical and tactile communication with each other," said José Halloy, who co-authored the research, which is outlined in this week's Proceedings of the National Academy of Sciences. "They can also use vision." Halloy, a scientist in the Department of Social Ecology at the Free University of Brussels in Belgium, added, "When they encounter each other they recognize if they belong to the same colony thanks to their antennas that are 'nooses,' that is, sophisticated olfactory organs that are very sensitive."
