Modern dog breeds genetically disconnected from ancient ancestors
Cross-breeding of dogs over thousands of years has made it extremely difficult to trace the ancient genetic roots of today’s pets, according to a new study led by Durham University. An international team of scientists analyzed data of the genetic make-up of modern-day dogs, alongside an assessment of the global archaeological record of dog remains, and found that modern breeds genetically have little in common with their ancient ancestors.
Dogs were the first domesticated animals and the researchers say their findings will ultimately lead to greater understanding of dogs’ origins and the development of early human civilization.
Although many modern breeds look like those depicted in ancient texts or in Egyptian pyramids, cross-breeding across thousands of years has meant that it is not accurate to label any modern breeds as “ancient,” the researchers said
