Archaeologists and geneticists have found specimens of the oldest known dogs, and the discovery is history

Two genetic studies shatter the old idea of ​​domestication, revealing that dogs coexisted with human groups thousands of years before agriculture.

Long before cattle, villages and the first grain fields, there was something with human groups in Europe and western Asia.It's not a stone tool or a new technology for surviving the last Ice Age winter.It is an animal.

For decades, the big question has always been the same: When did the wolf stop being a wolf?The answer was uncertain because the boundary between the two animals is not always visible in the bones.Many remains that were presented for years as "first dogs" turned out to be something else: extinct wolves, dark creatures or simple cases of archaeological curiosity in the face of evidence.

Now, two studies published in Nature have changed this panorama with extraordinary force.As the two works reveal, the relationship between humans and dogs is not only older than thought with genetic rigor, but also more complex and geographically extensive.News is not just about date.It is located at the end of the Paleolithic period indicating this date for the human world.

So far, the strongest genetic evidence for domesticated dogs dates back to about 10,900 years ago, in northwestern Russia.This has already been a remarkable chronology, but we are still in the throes of major changes with the emergence of many complex societies.For example, farming starts later.However, new research crosses the threshold of several thousand years and forces us to imagine a different scenario: at the end of the Ice Age, groups of hunter-gatherers crossed a hard, divided and changing continent... Already accompanied by dogs.

One of the works, led by Anders Bergström and Pontus Skoglund, analyzed 216 canid remains from European and Southwest Asian sites.To solve a huge technical problem – the very low preservation of DNA in many Paleolithic remains – the team developed a genetic capture system that made it possible to more precisely distinguish between the wolf and the dog.The result was conclusive: a specimen from Kesslerloch, Switzerland, dating back 14,200 years, was a dog.And not an isolated or strange animal, but an animal related to other dogs later from different regions.

The most interesting thing is not only his age, but also his relationship.

The details change a lot more than they seem.If the Swiss animal shared an ancestor with dogs from other parts of the world, we are not dealing with an independent and unsuccessful European domestication, but rather an early branch of the species that gave rise to modern dogs.In other words: the dog was then no longer a local experience.It was already part of a larger story.

The second study, led by William Marsh, Lachie Scarsbrook and Laurent Frantz, expanded the map even further.Using nuclear and mitochondrial genomes from remains found in Turkey, Britain and Serbia, the team identified Paleolithic dogs in Pınarbaşı, in Anatolia, dating back to about 15,800 years ago, and in Gough's Cave, in England, from about 14,300 years ago.The really surprising thing is that both were close together.related to each other, despite being separated by thousands of miles.

And this is where the story gets really interesting.Because these dogs do not seem to be connected to any single human culture.On the contrary: they arise in contexts belonging to very different groups, such as Magdalenian, Epigrebetan and Anatolian hunter-gatherers.That is, societies with different traditions, regions and possibly languages.However, from a genetic perspective the dogs were very similar to each other.

This shows something powerful: that the dog circulates among human groups.It is exchanged, sent or accompanied by contacts between communities.Just like a technique, a valuable raw material or an object of prestige, the dog can be a desirable, useful and recognized social innovation.It not only helps to live;It can also help connect very different human worlds.

The discovery isn't just about animals: it's also about how humans organize themselves

There are other important facts that help to understand the purpose of this paper.As both papers show, dogs appear to have arrived in Europe long before agriculture, and moreover, they survived the great transformations of the Neolithic.When the first farmers from Southwest Asia entered Europe about 9,000 years ago, they brought their own domesticated animals with them.But European hunter-gatherer dogs did not disappear.On the contrary: they made a significant contribution to the genetic background of later dogs, and perhaps also to many of today's European dogs.

It contrasts with what happened to the people.In many parts of Europe, the arrival of farmers meant a very deep genetic replacement of previous populations.The same did not happen with dogs.It was about mixing, staying and living together.The difference, apparently secondary, says a lot about the social flexibility of the communities and the practical and symbolic role that the dog already had.

What did those first dogs do?The knowledge of the world still exists.We don't know if they hunted, guarded, transported, scavenged remains, or simply bypassed human settlements using useful connections.But there are some signs: in some places, dogs look like people when they die;everything indicates a close, permanent and intimate relationship.

And perhaps therein lies the true importance of this revelation.Not to find the absolute "first dog" - the question remains open - but to be sure of the time when dogs were already part of the West Eurasian world.Not as a novelty, but as a known and widespread presence.

The house of the dog continues to keep a secret: exactly where it started, with the crowd and under what conditions.But now we know what is important.Before the wheat, before the sheep and before the lamb, there was a covenant there.And he left his mark on ice, bones and history.
