For dog lovers, comparative psychologists Friederike Range and Zsófia Virányi have an unsettling conclusion. Many researchers think that as humans domesticated wolves, they selected for a cooperative nature, resulting in animals keen to pitch in on tasks with humans.
But when the two scientists at the Messerli Research Institute at the University of Veterinary Medicine Vienna studied lab-raised dog and wolf packs, they found that wolves were the tolerant, cooperative ones. The dogs, in contrast, formed strict, linear dominance hierarchies that demand obedience from subordinates, Range explained last week at the Animal Behavior Society meeting at Princeton University. As wolves became dogs, she thinks, they were bred for the ability to follow orders and to be dependent on human masters.
Range and Virányi developed their new portrayal of dogs and wolves by giving a series of tests to socialized packs of mixed-breed dogs and wolves, four packs of each species, containing anywhere from two to six animals each. The scientists raised all the animals from about 10 days old at the Wolf Science Center in Game Park Ernstbrunn, Austria, living with them 24 hours a day until they were introduced to pack life, so that they were accustomed to humans.
