From chihuahuas to Saint Bernards, Swedish scientists say all modern dogs originate from a small number of female wolves living in East Asia some 15,000 years ago.
By analysing hair samples from more than 500 different breeds from all over the world, the scientists discovered all dogs share the same genetic pool but that East Asian dogs had a higher genetic variation.

"This makes it probable that dogs originated in East Asia and spread all over the world," a senior scientist at the Swedish Royal Institute of Technology, Peter Savolainen, said.

{didn't we just have some paleo-guys announcing the presence in North America of indigenes for at least 30K years? didn't the self-same indigenes have dogs?}
