Today’s Dogs Genetically Distinct From Ancient Breeds
Salukis appear genetically different because they were geographically isolated and were not part of the 19th century Victorian-initiated Kennel Clubs that blended lineages to create most of the breeds we keep as pets today. Saluki-like animals appear on ancient Egyptian tombs but the modern-day breed is not the same. (Keith Dobney)
Modern-day man’s best friend has little in common genetically with the dogs domesticated thousands of years ago by our ancestors, according to a new international study.
Led by the U.K.’s Durham University, the research team studied the genetics of 35 living dog breeds compared with wolves and what is known about ancient dogs from archaeological records.
Despite superficial similarities in appearance, cross-breeding over thousands of intervening generations means that it is incorrect to classify breeds like the Afghan Hound as ancient.
Canine genetic diversity has also been impacted by human migration patterns and major events like world wars.
Study lead author Greger Larson at Durham University noted that the results show how little we know about dog domestication, such as where and how often it occurred during the last 15,000 years.
“We really love our dogs and they have accompanied us across every continent,” he said in a press release. “Ironically, the ubiquity of dogs combined with their deep history has obscured their origins and made it difficult for us to know how dogs became man’s best friend.
“All dogs have undergone significant amounts of cross-breeding to the point that we have not yet been able to trace all the way back to their very first ancestors.”
