Pre-existing capacity of wolves to learn from humans may have led to dogs' domestication

Washington, Dec. 4 : Wolves are able to learn from observing humans and pack members where food is hidden and recognize when humans only pretend to hide food, according to a study.


These findings imply that when our ancestors started to domesticate dogs, they could have built on a pre-existing ability of wolves to learn from others, not necessarily pack members.

The paper suggested that humans domesticated dogs about 18 thousand years ago, possibly from a European population of grey wolves that is now extinct.

But it remains unknown how much the ability of dogs to communicate with people derives from pre-existing social skills of their wolf ancestors, rather than from novel traits that arose during domestication.

In a recent study, Friederike Range and Zsofia Viranyi from the Messerli Research Institute at the University of Veterinary Medicine Vienna investigated if wolves and dogs can observe a familiar "demonstrator" - a human or a specially trained dog - to learn where to look for food within a meadow.

The subjects were 11 North American grey wolves and 14 mutts, all between 5 and 7 months old, born in captivity, bottle-fed, and hand-raised in packs at the Wolf Science Center of Game Park Ernstbrunn, Austria.

The wolves and dogs were two to four times more likely to find the snack after watching a human or dog demonstrator hide it, and this implies that they had learnt from the demonstration instead of only relying on their sense of smell. Moreover, they rarely looked for the food when the human demonstrator had only pretended to hide it, and this proves that they had watched very carefully.

The researchers conclude that the ability to learn from other species, including humans, is not unique to dogs but was already present in their wolf ancestors. Prehistoric humans and the ancestors of dogs could build on this ability to better coordinate their actions.

The study has been published in the journal Frontiers in Psychology.
