Cross-Breeding Of Dogs Has Made It Difficult To Trace Their Genetic Roots

Modern Dog Breeds Genetically Disconnected From Ancient Ancestors -- E! Science News

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.

My Comment: These results (I suspect) are going to be fascinating to read about when they are finally completed.
