In a new study, published in the Journal of Experimental Biology, scientists in the Department of Biological Sciences at Vanderbilt report definitive evidence of a specific mechanism within ants that is responsible for unlocking aggressive behaviors toward other ants. The research—the first to pinpoint this mechanism and its precise role in ant biology—reports a social characteristic that could help account for their evolutionary success…"
