Researcher explores close prehistoric relationship between humans and dogs
Man's best friend came about after generations of wolves scavenged So the history of dogs may involve three major stages including loosely. Descended from the grey wolf, domesticated dogs have been companions to humans for about years, a genetic study has shown. Facebook Dogs may be man's best friend, but new research on ancient canine remains shows about the changing nature of the relationship between humans and dogs.

Prof Savolainen, of the Royal Institute of Technology, Solna, Sweden, said this indicates "an ancient origin of domestic dogs in southern East Asia 33, years ago.

Davis, John, circa - Alamy Prof Savolainen said: Although this dispersal is believed to have been associated with the movement of humans, the first movement of man's best friend out of south-east Asia may have been self-initiated.
Alamy This may have been owing to environmental factors, such as the retreat of glaciers, which started about 19, years ago. Dogs from one of these groups then travelled back towards northern China, where they encountered Asian dogs that had migrated from south-east Asia. Perri says that she is excited that someone is looking at new techniques to solve the heated debate over the domestication of dogs.

Most researchers agree that by 20, years ago we almost certainly had domestic dogs and that domestication first occurred somewhere in Eurasia. But there is a lot of debate on whether this first happened in Asia and spread west or the opposite.The Real Life Wolf Man
Some researchers even believe domestication began much earlier. Perri was a coauthor on a paper which theorizes a dual origin, with domestic dogs appearing both in East Asia and Europe between 14, and 6, years ago. Part of the problem with distinguishing between wolves and dogs is that both types of bones turn up relatively frequently at archaeological sites across the board.
Perri says that in the glacial periods, evidence of skinning marks on bones discovered suggests humans would sometimes hunt wolves for the valuable insulation offered by their pelts. Interspecies competition which led to dead wolves also occurred, with humans stealing freshly killed meal from a pack and vice versa.
As a result, Perri believes that the diet of wolves would not have been that different from humans and the dogs that ate their scraps in the Paleolithic—which would make it difficult to use nitrogen or carbon isotope studies to mark any difference between wolves and their sellout cousins.
However, other isotopes—such as oxygen or strontium—could hold the key to separating wolf from dog, since their signatures can be traced to the subtly different environmental conditions.
Dog DNA study reveals the incredible journey of man's best friend
Scientists could see how far a canine moved and through which kinds of environments, knowing that domestic dogs would likely be less mobile and stick closer to humans. One of Losey's projects involves the excavation of dog remains between 5, and 8, years old at Lake Baikal, Siberia, the deepest freshwater lake in the world.
What's striking about the find is it reveals dogs were buried alongside humans in cemeteries, pointing not only to some of the earliest evidence of dog domestication but also suggesting dogs were held in the same high esteem as humans.
Dogs seem to have a very special place in human communities in the past.
As soon as we see skeletal remains that look like the modern dog—say 14, years ago—we see dogs being buried. Clearly, people long ago began breeding dogs for specific purposes.
The wolves likely foraged around human campsites, gradually growing less inhibited. Once their potential as companions and workmates became apparent, they were domesticated and selectively bred. Somewhere between 10, and 15, years ago, the wolf had evolved into an animal genetically indistinguishable from the modern dog.
