smell is innate (an instinct) rather than learned. These scientists
presented 30 different scents to honeybees and monitored their
brain activity in order to see which part of the bee's brain became
active when they smelled each scent. They found that the different
brain patterns activated for each scent were identical within the
individuals of a species. This means that smells are not learned
individually, but are shared by the entire species. 1 MAY 1999, P. 27
