According to a new study, a submerged puppy found in Siberia is not a dog. Instead, a cute and cuddly dog is a little wolf.
In a new study aimed at understanding dog breeding, researchers analyzed the genome of a puppy and the genes of 72 ancient wolves. The puppy, discovered in the Siberian permafrost in 2018 and whose list has been debated since then, was named “Dogor” and was perfect, with short hair and an unbroken beard. Initially, scientists could not say whether the 18,000-year-old puppy was a wolf or a dog, but new analysis reveals that it was a wolf and was not closely related to the original dogs.
“We know that dogs were the first animal to be bred long ago during the winter,” said Anders Bergström, a postdoctoral fellow in ancient genomics at the Francis Crick Institute in London. But some aspects of domestication are some of the great mysteries of human prehistory; he told Live Science. “We do not know where the world is,” Bergström said. “We do not know which group of people is involved, and we do not know if it happened once or many times.”
The wolf is crying
The doctor’s genome was one of 66 previously unexplored species of wolves studied by Bergström and his colleagues. They also traced the genes of five consecutive ancient wolves and one ancient cave, another wild dog species that still exist in parts today. of Asia.
Researchers were seeking advice on the origin of the pet dogs (Canis lupus familiaris). Dogs were bred from wolves (Canis lupus), but the genetic makeup of modern wolves has changed dramatically over the years to reveal which wolves have abandoned their wild ways to meet humans. Bergström said it is essential to look at wolves from when the dogs were bred – between 30,000 years ago and 14,000 years ago, to identify the closest ancestors of the first dog breeds.
The 72 samples cover 100,000 years of prehistory in Europe, Siberia, and northwestern North America. Genomes have shown that wolves thrived during the ice age, with the number of people connected worldwide. However, the most exciting results were related to the wolf to dog. Researchers have found that dogs are more closely associated with the ancient wolves from eastern Eurasia than the ancient wolves from western Eurasia.
“This suggests that domestic farming may have occurred somewhere in the East, somewhere in Asia, and probably not in Europe,” Bergström said. “However, Asia is too big; we can’t diminish with more precision where it happens.”
Northeastern Siberia, where Dogor is located, does not appear to be the basis for genetic mutation, says Bergström, as the region’s wolves are not closely related to older dogs. But there are many other places in Asia where the DNA of the ancient wolf has not yet been collected and studied, so it is possible that pre-dog wolves came from an undeveloped area.
