Researchers say they found birthplace of dog

A team of Swedish and Chinese researchers say they have pinpointed — at least more than it has been pinpointed up to now — the place where, 16,000 years ago, the wolf was tamed and evolved into the dog.
It was in China, on the southern shores of the Yangtze River, they say.
Their findings are contained in an article in the latest issue of scientific journal Molecular Biology and Evolution.
“For the first time … it is possible to provide a detailed picture of the dog, with its birthplace, point in time, and how many wolves were tamed,” says Peter Savolainen, a biologist and member of the research team at the Royal Institute of Technology (KTH) in Stockholm.
Together with Swedish colleagues and a Chinese research team, Savolainen has made a number of new discoveries about the history of the dog — including the most specific date and birthplace yet offered.
“Our earlier findings from 2002 have not been fully accepted, but with our new data there will be greater acceptance. The picture provides much more detail,” says Savolainen.
Savolainen said the research indicates that the dog has a single geographic origin but descends from a large “large number of animals – at least several hundred tamed wolves, probable even more,” according to Science Daily.
The theory that the domestic dog originated in East Asia was challenged earlier this month by an international group of researchers who say African dogs are just as genetically diverse.
That research, based on analyzing blood samples from dogs in Egypt, Uganda and Namibia, shows the DNA of dogs in African villages is just as varied, indicating it could have been where wolves made the transition to become dogs.
