After analyzing the DNA of hundreds of dogs from Europe, Asia, Africa and North America, scientists found that all the dogs in the world had similar genetic sequences, so they concluded that all the world's domestic dogs evolved from East Asian wolves about 10,000 years ago. The ancestors of these dogs and the earliest settlers of the Americas crossed Asia and Europe together through the Bering Strait to reach the Americas. Scientists in Sweden and China studied the genes of 654 dogs and found that East Asian dogs have a strong genetic diversity, suggesting that East Asians were the first to tame wolves into dogs.
The findings, published in the latest journal Science, led the study, Peter Savoreen of the Royal Swedish Institute of Technology, said that humans initially speculated that the dog's ancestors came from the Middle East based on little evidence, because some archaeological finds in the Middle East prove that many animals were tamed in the region. Researchers from the United States, Latin America and Sweden have found that dogs with genes similar to those of East Asian wolves appeared in the Americas before European settlers arrived in the 15th century. This suggests that the first settlers who arrived in the Americas through the Bering Strait 10,000 years ago came to the Americas with tamed dogs.
Karls Vera, a researcher at Opsala University in the United States, said the presence of dogs could explain why settlers on the American continent dispersed relatively quickly. The two studies disagree on when dogs were domesticated from wolves, with the dog's mandible, originally found in Germany about 10,000 years old, and a team of Swedish and Chinese scientists arguing that DNA analysis and archaeological findings combined to suggest that dogs were domesticated 10,000 years ago.

A long, long time ago, somebody thought it would be great if wolves could help us hunt, so we organized people to hunt wild wolves, and wild wolves were very wary of people and very afraid of people. Since wolves are carnivores, people give the meat they hunt to wolves, and because hunting is not very easy, sometimes there will be very little meat, so the ancients wondered: if you put some grains in the meat, the wolf will also eat.
So the ancients put some grain in the meat. The hungry wolf ate happily. Slowly, as time passed, wolves became less wary of people.
The she-wolf gave birth to a baby wolf, and the baby wolf was not wary of people because she had seen people all the time. The ancients took the wolf out to hunt, and the wolf cooperated very well to hunt the target, and the man and the wolf got better and better, and the relationship became better and better, and the food they could get more and more, and so they cooperated from generation to generation, because the wolf ate meat with grain for a long time, and the stomach changed from generation to generation, and it became omnivorous. Well written.

The wolf is wild, and the dog is a dog breed that slowly evolved after the wolf was domesticated by humans, and like other poultry and domestic animals, it became what it is now after being domesticated by humans.

The wolf eats meat for thousands of miles, and the wolf can't walk anymore, and the piece is caught. He fled, but the meat was eaten by the wolf that went ahead. So he had to eat, but he didn't want to.
I can't help but come back and take refuge with people. for they gave him meat to eat. But at the cost of having to help people do something.
He agreed. He thought he was still a wolf. In fact, he is already a dog.
-
Because dogs evolved from wolves.
Remember.

Quite simply, it's the same as why pigs are your ancestors!!

The ancestor of the wolf was a small ancient cat. The little ancient cat, also known as the ancient cat, is considered to be a modern carnivore feline.
Canidae, bears, weasels, hyenas.
Civetidae, mongoose.
The common ancestor of other animals. Because the place where the little ancient cat lived changed, it eventually became a different animal, and as the species evolved, it became many different, and finally became famous for its dog and wolf shapes.
The evolution of the little ancient catThe small ancient cat lived 40 million to 50 million years ago, and the fossils were found in the Lower Eocene to the Upper Eocene in North America, and the Upper Eocene in Europe and Asia. In the long years that followed, the little ancient cat evolved into a lot of forms and species, and in the direction of the wolf, some individuals of the little ancient cat evolved into the dusk dog of the caninian suborder more than 30 million years ago. The Dusk Dog is about 80 centimeters long and looks like a civet or a tiny raccoon.
Its body and tail are long and flexible, and its limbs are weak and short. Like modern wolves, they preferred to live in packs.

The ancestor of the dog was the wolf.
Dogs are bred and domesticated by wolves for more than 10,000 years, and although they have been domesticated and raised for a long time, they still retain the habits of primitive wolves in their nature.
Nowadays, some dogs still retain the habits of wolves, such as leaving their own scent to divide territory, bury food, etc., but they are already very docile and loyal to humans by humans, and some breeds are not aggressive.
Difference Between Dog and Wolf
1. Physical differences
Although dogs and wolves have the same number and location of teeth, wolves have larger and stronger teeth. The reason may be because wolves need to hunt in the wild for things like bitten bones, but dogs' teeth have evolved to be more like scavengers of human garbage.
Compared to wolves, dogs have rounder faces and larger eyes. They also evolved floppy ears and curly tails. But the tail of a wolf is pointed, longer than that of a dog, and sickle-shaped.
2. The dependence on human beings is different
Without the help of humans, dogs can barely survive in the wild. Although there are some wild dogs, they usually don't do well because their genes have been domesticated to the point where it is almost difficult to survive fully in the wild.
3. Wolves mature faster than dogs
This makes sense, as the young wolf must mature as quickly as possible to survive in the wild, while the domestic puppy does not need to worry about survival, and the latter enjoy an easier life.
The tail of a dog is short and thin. The wolf's tail is long and thick, and the wolf relies on the tail to maintain balance when running. You can compare the earth dog with the wolf dog, and you can see it. >>>More
There are many reasons for changing the surname. Plug the door upside down, commemorate someone, a certain dynasty or something, avoid trouble, and give the royal family a surname... >>>More
Wolves move in packs or alone. In small groups during the breeding season, wolves often form large groups to prey on ungulates in the Taiga region of North America in winter, with the largest pack reaching 36 in Alaska, but generally no more than 20 wolves. >>>More
Feelings can be cultivated, in fact, dogs are also afraid of people. To overcome this fear on your own, in fact, many animals have their cute side. Truth be told, sometimes dogs are more loyal than people.
In fact, this kind of grass-eating behavior often occurs in dogs and cats, and it is called "pica". Common in young dogs, the possible causes are diverse. There are many problems with abnormal behavior, nutrition, and lack of vitamins and minerals (trace elements). >>>More
