Ants and humans share a rare ability: each can work together in groups to mobilize oversized objects. In a new study, Prof. Ofer Feinerman's team from the Weizmann Institute of Science, led by Tabea Dreyer, drew upon this unique trait to conduct a fascinating evolutionary competition: Who is better at maneuvering a large load through a maze? The surprising results, published today, shed new light on group decision-making and the pros and cons of cooperation versus going it alone.
