Rare gene reveal the secret of dog friendship with humans

A new study revealed the gene that differentiates between dogs and
wolves with regard to human interaction, according to the British Daily Mail, the study indicated that the dogs were genetically infected when they were inclined to make them very social.

According to researchers this gene appears in people suffering from the "Williams Bjorn" syndrome, a condition that causes the patient's love for all people.

In a study supervised by the biologist Bridget von hold at Princeton University, the search team used 18 domesticated dogs and 10 wolves raised in captivity to test ways to solve problems.

The animals were given a gas cube containing sausages and must be opened within two minutes with the presence of humans and the researchers found that the dogs were more inclined to abandon the task and stare at the human, while the wolves have persisted and eventually solve the puzzle regardless of the person's presence.

In a second test, the human participant was asked to sit within a circle before calling the animal by name and encouraging him to approach and communicate with him without leaving the circle, and then the dogs approached and wolves of the circle of man but after only a few seconds the Wolves lost interest and subsided while the dogs remained for long periods of time with familiar and unfamiliar persons.

After the experiments, the team analyzed animal blood samples and discovered that the dogs possessed similar genes for someone with Williams syndrome. Bjorn, a human condition that includes distinctive facial features, cognitive disabilities and excessive social tendencies.

"The dogs were thought to have developed their social behavior of learning during life with humans," said Monique O'Dell, an animal scientist at Oregon State University, and but this new evidence suggests that dogs have a genetic condition that produces a strong motivation for social contact compared to wolves.
