Modern dog lost its roots

British researchers say that breeding dogs for thousands of years has made this animal in modern times "isolated" with its ancient ancestors, according to UPI news agency.

An analysis of the genetic structure of modern dogs shows that the current breeds have little in common with their ancient ancestors.

That makes it difficult to trace the ancient genetic origins of pets today, researchers from the University of Durham (UK) admit.

The results of genetic studies show that breeds like Akita, Afghan Hound and Chinese Shar-Pei, which are often classified as 'ancient', are not much closer to the first domestic dogs than most other breeds.

This has hindered the initial history of dog domestication including the place, the time and the number of times it took place, the team said.

'This lovely animal has accompanied us through every time, continent. Ironically, however, the ubiquitous presence of dogs along with their mysterious history has made the origin of this animal vague and makes it difficult for us to know if the dog has become my best friend. people like that, ' said evolutionary biologist Gregor Larsen.

'All the dogs have gone through so many hybrids that we cannot trace back to their original ancestors , ' Larsen emphasized.
