>> 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 that it must have happen twice in two separate places, several thousand miles apart.>> The research use genetics to unravel Canine evolution re-history, putting man and dogs together 15,000 years ago, that's 5,000 years before cows, goats and pigs arrived. A team from Oxford University said, DNA map of ancient dogs shows two separate populations of wolves, thousands of miles apart in Europe and Asia and none in the middle.
00:00:51
They used the DNA of a 5,000 year old dog found in Ireland, a technique becoming ever easier, according to professor Greger Larson.>> The speed with which and the ease with which we can now generate ancient genomes is staggering. We just go, I don't wanna wonder, I don't wanna suppose, I don't wanna speculate about what happened, I just wanna watch the movie.
00:01:12
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 out all the guess work 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 gray wolves became today's Yorkshire Terriers.
