A 4,800-year-old dog has made a pawscovery at Newgrange monument in Co Meath which has helped to explain how our little furry friends became man’s best friend.
New studies has shown that the domestication of dogs from wolves has actually twice on opposite sides of the planet, proving that the relationship between dogs and humans was set in stone from the beginning.
This study proves that wolves became pets more than 12,000 years ago in both Europe as well as the Far East.
From this they started looking through bones of the canine fossil originally excavated from the Newgrange passage graves decades ago.
“We were actually primarily looking for cattle bones, but we came across a dog bone,” he said. “It occurred to me, ‘Why don’t we look at the genetics of this dog?’”
It turned out the sample was in perfect condition and his PhD researcher and joint first-author of the paper Victoria Mullin was able to sequence the dog’s whole genome despite the amount of time passed.
Prof Bradley said he knew Oxford had a project running on dog ancestry and his group joined them, bringing their Newgrange dog data with them.
“We found that the [Newgrange] dog was like European dogs and shared modern dog ancestry, but there was something extra. It was like a ghost ancestry with something else.”
A large research team at the university had recovered DNA from 59 ancient dogs living between 3,000 and 14,000 years ago.
The team also looked at the DNA of 2,500 previously studied modern dogs to solidify their findings.
“The theory that fitted best was you had a European domestication in parallel as an Asian domestication,” Prof Bradley said.
This would have happened more than 12,000 years ago.
“But then subsequently there was a migration of these Asian dogs into Europe, where they mixed with the European dogs to bring what we have today.”
Prof Bradley’s human and animal DNA studies convinced him these dogs were brought into the West by the first farmers who migrated into Europe from the Near East.
People say ‘time will tell’, well it has and mans best friend is here to stay. Her’s to the next 12,000 years!
