It may be one of the doggone doggiest things a doggy can do, chasing down a stick or a ball and then

bringing it back.

But when it comes to playing fetch, perhaps the apple doesn't fall all that far from the evolutionary tree.

Because a new study shows that some wolfpups demonstrate the same innate fetching skill.

A finding that suggests that an ability to playfully interact with people might have been around in ancient wolves before they transitioned into domesticated dogs some 15,000 years ago.

The work is in the journal I science. Researchers were interested in

understanding how domestication affected canine behavior. So they raised

several litters of both wolf and dog puppies and ran the little fur balls through a standard series of behavioral tests.

In one of those tests, a puppy assessor, someone the animals never before met, would toss a tennis ball across the room and encourage the pup to retrieve it.

Wolf pups in the first two liters tested showed little interest in playing ball.

But three of the six pups in the third letter caught on quickly.

Two wolves named Elvis and Lenny brought the ball back in two out of three throws, while the

intrepid little sting knocked it out of the park and carried the ball back all three times.

These results were actually unexpected.

The researchers had thought that the ability to socially engage with unfamiliar humans was something that likely arose after dogs were

domesticated. The fact that a few of the wolfpups were up for some fun

suggests that the potential for a connection between canines and people could have been present from the get-go,
