A team of researchers from Sweden has conducted a recent study which shows that the domestication of dogs occurred much earlier than previous studies suggested.
The researchers conducted a genetic study which indicated that dogs may have begun to separate from wolves approximately 27,000 years ago.
The recent discovery challenges previous theories that the domestication of dogs happened much more recently, about 15,000 years ago, during the time when humans changed their basic occupation from hunter gatherers to farmers.
Some scientists believe that the recent findings may explain the deep bond that exists between humans and dogs.
Other researchers believe that humans started to tame dogs around the time they discovered agriculture, when they settled and formed communities.
However, the new study, which was conducted by a team of scientists led by Dr. Love Dalen from the Swedish Museum of Natural History in Stockholm, wants to challenge previous theories.
Experts in dog evolutions believe the dog evolved from wolves and the transformation process had been a slow one.
It first began with subtle behavioral changes in the dogs.
Dr. Dalen said that one of the scenarios is that wolves started to follow humans wherever they went and domesticated themselves.
Another theory points to the fact that early humans caught wolves when they were cubs and kept them as pets, which led to the domestication of the wild wolves, eventually.
If this scenario is the right one, then it means that dogs were first domesticated by early humans who were hunter gatherers and led a somewhat nomadic lifestyle.
Peter Smith, a researcher and chief executive at Wildwood Trust in Kent, said that this could have been the beginning of the relationship between humans and dogs, a relationship that has developed and strengthen over tens of thousands of years.
Smith stated in an interview with the BBC News that this new study suggest that the profound connection that exists today between dogs and humans is a continuation of the relationship between early humans and wild wolves.
This relationship has evolved and became stronger and stronger over the millennia, which is why humans love dogs so much, and vice versa.
According to Smith, dogs are part of the human evolution and played an important part in the formation of modern societies.
The researchers detailed their findings in the journal Current Biology.
