November 23, Researchers at Sweden's KTH Royal Institute of Technology say they have found further proof that the wolf ancestors of today's domesticated dogs can be traced to southern East Asia -- findings that run counter to theories placing the cradle of the canine line in the Middle East. Data on genetics, morphology and behaviour show clearly that dogs are descended from wolves, but there's never been scientific consensus on where in the world the domestication process began. The Y data supports previous evidence from mitochondrial DNA.

When the Wild Wolf was Tamed

The domestic dog is one of the most genetically diverse species on the planet, but how and when and where they evolved has been up for debate amongst canine geneticists, perhaps until very recently. Fifty-eight canine genomes from around the world were sequenced, from wolves to wild dogs to huskies. Southeast Asian dogs had the most diverse genome compared to other dog populations and were the most genetically similar to grey wolves, indicating that they were the most ancient evolutionary branch of the domesticated dog. They evolved from wolves who, like cats, ate our scraps, before we even learned to grow our own food 10, years ago.

The dhole is a highly social animal, living in large clans without rigid dominance hierarchies [11] and containing multiple breeding females. It is listed as Endangered by the IUCN as populations are decreasing and are estimated at fewer than 2, adults.

The love affair between humans and dogs has been going on for thousands of years. But when and where dogs first branched off from wolves is the source of scientific debate. Over the past decade, various groups have posited different locations as the birthplace of the dog, including Europe and the Middle East. Now, an international group of researchers presents another possibility.
