>> How man's best friend became domesticated is more complicated than first thought. New research suggesting wild wolves and ancient man teamed up on more than one occasion, according to Reuters Science correspondent Ben Hirschler.>> So, until now, people thought that dogs were domesticated just once in one place at one time.
00:00:20
But this latest evidence suggest it must have happened twice in two separate places, several thousand miles apart.>> The research used genetics to unravel canine evolutionary history, putting man and dogs together 15,000 years ago. That's 5,000 years before cows, goats and pigs arrived. The team from Oxford University say a DNA map of ancient canines shows two separate populations of dogs, thousands of miles apart, in Europe and Asia and none in the middle.

They used the DNA of a 5,000 year old dog found in Ireland, a technique becoming ever easier, according to Professor Gregor Larson.>> The speed with which and the ease with which we can now generate ancient genomes is staggering. We just go, well, I don't wanna wonder, I don't wanna to suppose, I don't wanna speculate about what happened.
00:01:11
I just wanna watch the movie. So we get the genomic data, we get the shape data, and we can actually see what happened over the last 15,000 years. And that takes all the guesswork out of it. And we can just say, look what we've got! And now we're just telling a story.

>> Work yet to show us exactly how grey wolves became today's Yorkshire terriers.
