Wolves could be man's best friend too, a new study reveals.

Scientists proved that wolves can distinguish between strangers and people they know, and show much more affection to those familiar to them.

What's more, the familiar person can help calm them down in stressful situations.

Their reactions show that an an attachment prior to domestication 15,000 years ago could have led to the dogs we have today.

Scientists tested 10 wolves and 12 dogs to see how they behaved in strange and stressful situations.

The wolves showed the person they knew more affection by getting closer to them and spending a longer time greeting them.

This finding contradicts the idea that dog's attachment to humans only developed after humans domesticated them.

The study, published in the journal, Ecology and Evolution, shows that this connection to humans did not evolve specifically in dogs.

“It was very clear that the wolves, as the dogs, preferred the familiar person over the stranger," said Dr. Hansen Wheat, a behavioral ecologist from Stockholm University, Sweden, and lead author of the study.

"But what was perhaps even more interesting was that while the dogs were not particularly affected by the test situation, the wolves were. They were pacing the test room.

"However, the remarkable thing was that when the familiar person, a hand-raiser that had been with the wolves all their lives, re-entered the test room the pacing behavior stopped, indicating that the familiar person acted as a social stress buffer for the wolves.

"I do not believe that this has ever been shown to be the case for wolves before and this also complements the existence of a strong bond between the animals and the familiar person.”

The team have been raising the wolf and dog puppies from the age of ten days.

This test took place when they were 23-weeks-old.

"We felt that there was a need to thoroughly test this," Wheat said.

"Together with earlier studies making important contributions to this question, I think it is now appropriate to entertain the idea that if variation in human-directed attachment behavior exists in wolves, this behavior could have been a potential target for early selective pressures exerted during dog domestication."

The similarities between dogs and wolves can tell us something about where the behavior we see in our dogs come from.

"Wolves showing human-directed attachment could have had a selective advantage in early stages of dog domestication," Wheat said.

Wheat and her team at Stockholm University are continuing their work to learn even more about the behavioral similarities and differences between wolves and dogs.
