The bond between dog and man has ancient roots and, as research suggests, it really seems written in the DNAThe dog is probably the first animal to be domesticated, when humanity still consisted of hunter-gatherer groups: the most widely accepted hypothesis is that ancient wolves approached our settlements attracted by food scraps, initiating a coexistence that transformed into cooperation and, finally, domestication.
One of the most discussed models comes from a study published in Science and led by Laurent Frantz of Oxford University: the theory of double domesticationAccording to this hypothesis, the transformation from wolf to dog occurred in two distinct areas, in Asia and between Europe and the Near East. Subsequently, the canine populations met and intermingled, explaining why many modern dogs show traces of both Eastern and Western genetics.
The analyzes of Ancient DNA and the archaeological finds published in recent years in journals such as Science e Nature outline a complex picture. A part of the scientific community is inclined towards aonly domestication occurred at least 15–23 years ago in Eurasia, followed by expansions, human movements, and interbreeding with local wolf populations. Other data, however, continue to support multiple scenarios. There is no definitive consensus, but the evidence agrees on some key points: the dog descends from a common ancestor of the gray wolf, domestication is very ancient, and subsequent genetic mixing made the origins more nuanced than previously thought.
Understanding how the human-dog relationship was born also helps those who travel with a pet in tow: the long coevolution explains the extraordinary sociality of the dog, its ability to adapt to new contexts, and its constant search for collaboration with us. All this makes it an ideal travel companion, provided its ethological and well-being needs are respected.
The most widely cited estimates point to at least 15–23 years ago. New findings and ancient DNA analysis may further refine these dates.
Yes, from a common ancestor of the gray wolf. Dogs don't descend directly from modern wolves, but they share an ancient origin and, at some stages, there has been interbreeding.
It depends on the samples analyzed (fossils and ancient genomes from different areas), statistical methods and the fact that over time there have been human movements e genetic mixingThe result is a rich and complex story, in which multiple hypotheses can explain different parts of the picture.
In short, whether it is a single or double origin, the evolutionary history of the dog confirms why it is today a traveling companion so special: he understands us, he trusts us and he has built a relationship with us that is unique in the world.
