Study: Dog has been man's best friend for 33,000 years

Dogs became self-domesticated as they slowly evolved from wolves who joined humans in the hunt, according to the first study of dog genomes.

And it shows that the first domesticated dogs came about 33,000 years ago and migrated to Europe, rather than descending from domesticated European wolves 10,000 years ago as had previously been thought.

Scientists have long puzzled over how man’s best friend came into existence but there is conflicting evidence on when and where wild wolves were first tamed.
