Is there any clear evidence for a single origin of domesticated dogs? Given that dogs can be bred with wolves, I see no reason why what we have now couldn’t be a mix of the results of multiple domestication events.
Taking a quick glance at http://en.wikipedia.org/wiki/Origin_of_the_domestic_dog , it seems that wolves were domesticated several times but all extant dogs are descended (at least matrilineally) from those domesticated around 15,000 years ago in China.
