Ball-rolling bees reveal complex learning

March 28, 2017

Bumblebees can be trained to score goals using a mini-ball, revealing unprecedented learning abilities, according to scientists at Queen Mary University of London (QMUL). Their study, published in the journal Science, suggests that species whose lifestyle demands advanced learning abilities could learn entirely new behaviours if there is ecological pressure. Project supervisor and co-author Professor … More Ball-rolling bees reveal complex learning
