It is not known exactly if it is a dog or a wolf. Or an ancestor of either or both.
The body of a puppy found frozen in Siberia with approximately 18,000 years old has puzzled scientists, who still cannot establish whether the specimen found belonged to either of the two animal breeds.
For now it is known that DNA sequencing has not been able to determine the species of the animal and therefore the researchers are conducting more studies of the surprising finding.
It is estimated that the canine was two months old when he died and his body has been preserved almost perfectly in the permafrost of the eastern Siberian region, with his fur, nose and teeth virtually intact.
Scientists believe that the recent discovery may represent an evolutionary link between wolves and modern dogs.
Radiocarbon dating was able to determine the puppy's age when he died and how long he has been frozen.
Genome analyzes showed that he was male.
The researcher Dave Stanton, from the Center for Paleogenetics of Sweden, told international media that, since the exhaustive DNA studies carried out failed to establish to which species the animal belongs, it is possible to think that the puppy comes from a breed that would be an ancestor Common dogs and wolves.
"We already have a lot of data, and with that amount of data, one would expect to know if it was one or the other (dog or wolf)," said the expert.
Another researcher from the Swedish entity, Love Dalen, published on Twitter that the specimen found may be a wolf cub or "the oldest dog ever found" and highlighted the surprising finding.
The scientists in charge of analyzing the animal's body announced that they will continue with DNA studies and anticipated that their findings could reveal a lot about the evolution of dogs.
The puppy has been baptized Dogor, which means "friend" in the Yakut language, and you can translate it as "Dog or ...".
It is believed that modern dogs are descendants of wolves, but there is a debate about when they began to be domesticated.
A study published in 2017 suggested that this process may have occurred 20,000 to 40,000 years ago.
