A team of researchers from the University of Arizona's Accelerator Mass Spectrometry Laboratory has recently revealed that dogs have been man’s best friends since early human history. The team said that they have proved to be the only loyal buddies of humans since more than 30,000 years.

The report reveals that the team of scientists has found skulls of dogs that were exhumed in two separate digs, one in Siberia and the other one in Belgium. These skulls have been found to be ancient and are known to be 33000 years old.

One of the authors of the study, Greg Hodgins, told reporters that the skulls are having short snouts along with wider jaws and crowded teeth. He told that these are unlike those had by wolves as they have longer snouts and narrower jaws that help them in hunting.

To find out the age of the unearthed skulls, the team of researchers used carbon dating and studied their bone structures. After the research, they concluded that domesticated dogs were solid enough. Also, they were found to have morphological characteristics.

Also, it is being said that the skulls of dogs found are no less than evidence of dog domestication since then, even before the domestication of any other animal such as cows or goats. “The interesting thing is that typically we think of domestication as being cows, sheep and goats, things that produce food through meat or secondary agricultural products such as milk, cheese and wool and things like that”, said Dr. Hodgins.

It was then concluded by the team that dogs are being kept by humans since ancient times, not only for protection but for companionship as well. Along with this, the most interesting part of the findings is the evidence that dogs were chosen the first to have a strong relationship with mankind amongst all other animals.
