 A new research in Britain has claimed that Man's relationship with his best friend, dog, has wiped out the dogs' history so much that it is impossible to tease out the details of their domestication.
According to researchers from the University of Durham in the UK, their complicated history involves being interbred, as well as transported around the world.
The researchers said, dogs were the first domesticated animal; however, many major questions about their domestication remain unanswered.
Lead study author Greger Larson, an evolutionary biologist at Durham said, using genetic data taken from modern breeds so far, it's not yet possible to look back more than about 150 years ago, past the time when Victorians began establishing the tightly defined breeds we know today.
He said for the previous 15,000 years or so, the genetic history of dogs is a big blurred mess Mr Mr Larson added that humans transported them around the world which even led to the disapperance of certain varieties. |
