Is Every Dog A Working Breed?

In a sense, every dog has always been a Working breed. Every one of them performed a specific job. In the 19th century, that broad job description was abandoned in favor of increasingly precise purebred classifications. Today, Working breeds have become highly specialized and compartmentalized into very specific roles. That can lead us to overlook the fact that canine utility was the spark that drove the entire evolutionary process–and that extended far beyond the wolf-to-dog transformation. It is debatable whether our species would have survived or thrived to populate so many parts of the world without canine assistance.

A couple of papers recently published in the journal, Nature, have brought this idea into sharper focus. Although conducted by different teams, both studies arrived at similar conclusions, providing the first definitive genetic evidence of when the human/canine partnership commenced. Their findings kick the domestication timeline back several thousand years earlier than previously believed.

There’s never been any shortage of canid fossils to study. The problem has been trying to distinguish the dogs from their wolf ancestors. Skull shape and jaw size have been the primary indicators until now. Obviously, that method was less than reliable when examining ancient fragments of bone. More importantly, domestication occurs as an incremental process. Physically, there was very little physical difference between wolves, early domestic dogs, and all those hybrid types in between.

DNA technology has been a game changer for making those judgment calls. For the first time, it has become possible to identify that critical genetic tipping point in the fossil record. The underlying research in these studies was based on a combination of bioarcheology and DNA sequencing. This approach was utilized by two separate but parallel research teams. Their methodology was somewhat different. The surprising part is that they arrived at the same startling results.
