How did dogs evolve? Did dogs evolve from wolves?

The first step in the evolution of dogs was taken about 100,000 years ago, because some wolves discovered that there were often sporadic foods to eat around humans, and they could get something for free, which was far better than hunting for their own hard work. In this way, a fortuitous discovery determines the emergence of a population. Then a series of evolutionary procedures were initiated, among which scavenging was very crucial, because this part of the wolves ate the food waste and spoilage food discarded by humans, and did not compete with humans for food, so they were tolerated by humans, so the dogs began the long march of evolution.

The final step of evolution was completed about 12,000 years ago, coinciding with the entry of humans into an agrarian civilization. Farming has given humans a fixed place to live, and dogs have finally lost their wolf nature and entered a new stage of development hand in hand with humans. This is an evolutionary process of human-dog interaction, zoologists have found that primitive tribes actually rarely raise dogs, most dogs survive on the edge of man and nature, but do not infringe on the interests of humans, they don't even bite chickens, so people don't hate it, and can also provide alarm services for humans, dogs are slowly accepted, and gradually integrate into the human community, and even enter the house.

In this long process, dogs are not idle, they are very active, and in order to survive better, they have learned to please humans. Zoologists have found that dogs from childhood to old age are lively and cute, which is an evolved ability, through which they can obtain a lot of benefits and live a very nourishing life, so they are said to have ideas and "conspiracy".

Unlike the opposition between the ancestors wolves and humans, dogs choose to be close and cooperative with humans, they know that obedience will be rewarded, and disobedience will be punished, so they continue to evolve according to the will of humans. As a result, the population multiplied rapidly, far surpassing their ancestors, the wolf. There are gradually all kinds of dogs in the world, and ornamental dogs invite pets to sell cuteness, and functional dogs can help their owners do things.

Perhaps, it was the wolf that chose humans in the first place, and evolved into dogs along with humans. There is an active side to this, which is a process of "I chose you, you chose me", so the evolution from wolves to dogs is a process of interaction with humans, but the pull of humans is too strong, people and wolves dance together, and the result is still human; When a wolf dances with a man, it becomes a dog.

Dogs evolved from wolves. Scientists believe that dogs were made by early humans from gray wolves.

Domesticated, domesticated 40,000 years ago, 10,000 years ago. Dogs belong to the phylum Chordates.

Subphylum Vertebrates, Mammalia, Subclass Euzoa, Carnivora, Suborder Schizopoda, Canids. Also known as "dog" in Chinese, dogs are found all over the world. Dogs, horses, cows, sheep, pigs, and chickens are called the "six animals".

Origin of species: Dogs were domesticated by wolves. As early as the hunter-gatherer era, dogs were domesticated as hunting assistants.

Therefore, dogs are considered to be the earliest domesticated domestic animals of humans. Dog bones have been found in Cishan in Wu'an, Hebei, Pei Ligang in Xinzheng, Henan, and Hemudu in Yuyao, Zhejiang, which proves that it has a long history of domestication. Jiao County, Shandong.

The dog-shaped skull unearthed in Sanlihe is vivid and realistic, allowing us to see the Neolithic Age.

Morphological characteristics of domestic dogs. The dog bones unearthed from the Banpo site in Xi'an, Shaanxi Province, have a small skull, a prominent frontal bone, a small flesh crack tooth, and a curved horizontal edge of the mandible, which is very different from the North China wolf, indicating that the history of human domestication of dogs is indeed very early.

There is a consensus that dogs originated from wolves, but there are different opinions surrounding the exact origin and time. The earliest evidence of a dog fossil is a 14,000-year-old mandible fossil in Germany, and these archaeological evidence supports the fact that dogs originated in Southwest Asia or Europe, while on the other hand, the skeletal identification features of dogs suggest that dogs may have originated from wolves, thus proposing the East Asian origin theory of dogs.

Researchers say it is possible that dogs have self-domesticated by finding humans and eating human leftovers. Israeli fossil and genetic research has identified the domestication of dogs as about 10,000 years ago, coinciding with the Agricultural Revolution, when humans transitioned from nomadic hunters to farming and living in settlements. Some scientists believe that wolves were attracted to the dumps of these early settlements, where they fed on leftovers from vegetable and cereal cultivation.

Specifically, dogs carried extra copies of the amylase gene compared to their wolf counterparts. In addition, dogs produce 12-fold more maltase-glucoamylase, which is a tie-in because of several mutations in the enzyme gene. Mutations in the third gene, SGLT1, improve the absorption of proteins by intestinal sugar.

Dogs were domesticated from wolves. There is some evidence that domestic dogs evolved from multiple species of ancient wolves, and that dogs exhibited the characteristics of one or more ancient wolves through intentional or unintentional crossbreeding. Although all wolves belong to the species Canis lupus, many subspecies of the species, present or past, differ to a greater or lesser extent in appearance, social structure or other characteristics.

For example, the Japanese wolf, which became extinct in the early twentieth century, was smaller than other species of wolves, with gray fur and a red underbelly. Japanese wolves may be more sole-hunting; The North American wolf, which still lives in some areas, is much larger than the other subspecies of the species, with fur ranging in color from nearly white to pure black, and at the same time, they also have a complex social structure and hierarchical behavior patterns.
