Bees can use tools to solve a problem, according to experiments that demonstrate their remarkably advanced cognitive abilities. The bees were given a customized version of an experiment that 100 years ago, showed for the first time that chimpanzees could figure out how to retrieve a banana they couldn't reach by stacking boxes.
Since then, several other primates, elephants and crows have joined an elite group of species known to be capable of this level of insight and spontaneous problem-solving. In the latest study, bees were shown to be able to roll a Styrofoam ball to a specific location and climb it to access an artificial flower if they can’t fly. The findings challenge the long-held assumption that insects operate solely on instinct.
