My own dog seems far from a wild wolf

If you’re like me, a spoiled, cheese-loving bad dog, the fact that your inner predator is probably not true.

But the main major study shows their physical transformation from wolves to wide sofa-hogging began in the middle stone age, much earlier than we thought.

“When you see a Chihuahua – it’s a wolf that now lives with humans for a long time it has been changed,” Researcher measured Evin in the MonTPeler study, “Researcher in the MonT9 study in this study.

He and his colleagues discovered that the transfection of our champion pets by victoria from true breeding probably began more than 10,000 years ago.

C ahee picture shows two canine skulls used in archaeological studies. It is a photograph of a wild wild clove (top) and a modern dog skull (bottom) used for the photogrammetry reconstruction of the 3D model in the studydiarrhea

Researchers study more than 600 skulls spanning 50,000 years of dog and wolf evolution

In a paper that was validated in the Worktid community, this international team investigated the research of the attention of Prastryoric Previk. Over more than a decade, they were collected, published and skalnel that sank a year that was 50,000 dog years long.

They created a digital 3D model of each of more than 600 Skulls they studied, and compared the characteristics, with their wild relatives – and their big relatives.

This is so that, almost 11,000 years ago, only after the ice age, the dog’s skull began to change its shape. When there was still a Blender, a dog like a female dog, there were many shorter and shorter snouts, tulo stockdors.

Dr ameng aheng from the University of Exier, not the publisher who led this project, explained in the BBC that it remains in the dog population that we see in the dog population.

“It was really surprising,” he said. “And it’s starting to challenge the idea of ​​why it wasn’t Victoria – and the Kennel club – that built this.”

The researchers produced digital scans of each step of their skulls. The pink skull on the left in this image is a modern dog with a shorter snout and the green image on the right is a scan of a bull terrier.

Domestication: An ancient mystery

Dogs were the first animals to be domesticated. There is evidence that humans have been living with cans for at least 30,000 years. Where and why the close first will remain a puzzle.

This study has revealed some physical evidence that the very first dog changed into the river Chresta, becoming a friend today. And the digital study of the skull they are excited about will allow them to answer more questions about the issue of domestication.

Some researchers have suggested that humans and wolves come together almost without accident, when the attack moves to the edge and

Cater harvests will get food again, and the moran gradually comes to be dug up to clear the apier forest and nearby predators.

Again why ultimately change the physical appearance of the dog, dr eREE said there are probably several reasons. He did not carry out our ancestors oleences for the head of the writing box and cute, snub mose but he explained: “It is interested in some of the animals that we see, all tracing to the type of saying that we see.

“It’s hard to decide which is the most important.”

For tens of thousands of years, the story of our humans and that of our dogs has been olangress. In another paper in this issue of Suprovitas, this is outlined by scientists in the ancient Chan Sc who lived among the central colonia.

They concluded that the domestic movement in the region is often accompanied by the migration of people – speculators, farmers, and pastoralists, and pastoralists. So our dogs have traveled with us – and have been enshrined in myths – for thousands of years.

I can not say that my own stubbornness, the terrier did not give me and anything that has wolfor domesticated domested in our ancestors. But I’m sure, as research shows, once healthy appears for some tetevrik, no money will return.
