 The researchers concluded that the difference does not stem from a difference in understanding of the task (their cognitive capabilities are largely the same), nor from a difference in social aspects (for both species, aggressive behavior by dominant animals was rare, as was submissive behavior by lower ranked ones).More likely is that dogs avoid potential conflict over a resource more than wolves do, something which has been observed in other studies as well.The wolves, but not the dogs, were then tested in pairs in a set-up with two identical apparatus 10 meters (39 ft) apart, requiring them to coordinate in time and space.
