"How do dogs come from? Dogs are domesticated by wolves, that's for sure." Chen Kan said that dogs are domesticated by wolves, and there is no doubt about this. The biggest evidence is that dogs and wolves are biologically the same species because their reproductive offspring does not have reproductive disorders, unlike mules.

The question now is, how do wolves become dogs?

"Didn't it mean that the wolf cannot be domesticated?" Teacher Chen Mei had not turned around yet.

"Yes, then in this case, how did the wolf turn into a dog?" Chen Kan asked back.

"This..." She was stunned when she heard Chen Kan say it. Yes, how could it become a dog? An animal like dog is not a species that nature itself has. This can be proved from the fossils that dogs are domesticated by wolves.

But wolves cannot be domesticated, or it is difficult. The ancients have known this long ago. The so-called "unfamiliar ungrateful wolf" means this, but in this way, isn't it a contradiction?

How did the dog come from?

Some people may say that according to current technology, some wolves can also be domesticated. This is indeed true. With current technology, many animals can be domesticated, but this is now, not ancient.

Let’s not talk about whether ancient humans had the ability to tame wolves. Even if they really encountered wolves that could be tameeded, would people at that time really take the initiative to tame wolves?

The answer is yes-no.

First of all, the risk of domesticating wolves is too high. If you are not careful and give you a mouthful at night while you are sleeping, it will be over. What's more, wolves are social animals. If you call friends, the entire tribe may suffer heavy losses. The ancient ancestors would not take such risks.

Even if one or two of them were lucky enough to be domesticated and they were really obedient, their bloodlines were difficult to reproduce because they were too small to form a population.

Secondly, wolves have no practical use to humans. Dogs are loyal friends of humans, but what are the uses of wolves? They cannot provide food for humans. Raise a wolf and then kill it as food. To be honest, the meat they pay for raising a wolf is much greater than the meat they get from a wolf. This is a loss-making business.

Finally, and most importantly, the wolf's recipes overlap with human's recipes. You can tell this just by looking at other domesticated livestock. The recipes of those domesticated animals are basically different from those of humans. For example, cattle and sheep eat grass, chickens eat insects, and they will not snatch food from humans.

Wolves are carnivores, and humans are also carnivores. Carnivore can provide people with a lot of fat and energy, and are an extremely important source of food. Humans cannot share it with wolves.

Dog recipes and human recipes are also staggered.

"Domestication is impossible, but dogs are indeed domesticated by wolves. What's going on?" After hearing Chen Kan's explanation, Teacher Chen Mei became even more dizzy.

"There is only one possibility left." Chen Kan shrugged.

"What?"

"Although dogs are domesticated by wolves, they are not domesticated by humans, but by wolves themselves." Chen Kan said with a smile.

"Tabulate yourself?" After hearing Chen Kan's words, she was stunned. She looked at Chen Kan as if she was looking at a mentally retarded. Can you still talk a little?

"Of course, this is just my guess. I have no evidence to prove it now, but as Holmes said, after excluding everything impossible, the remaining answer is strange, that is the truth." Chen Kan said dissatisfiedly. Chen Kan's view had also been discussed with several of his classmates. Their first reaction was the same as that of Teacher Chen Mei.

It sounds unreliable to tame yourself.

"It makes sense if you say this." Teacher Chen Mei thought about it carefully, and this conclusion seemed to be completely unacceptable.

"There will always be some elderly, weak, sick and disabled people in the wolf tribe. These wolves cannot adapt to group life and will be expelled from the group."

This situation does not only happen to wolves, but also occurs in many animal populations. Even if they are not expelled from the group, they will be unable to grab food due to their physical weakness, which will eventually lead to death.

The same is true for humans. In ancient times, when the elderly were old, they would take the initiative to leave the group and find a place to live and fend for themselves. What would promote "filial piety" in culture? The fundamental reason is that there was no such thing as it was. If there was this culture, why should it be promoted? If there was no corruption, why should it be anti-corruption and integrity?

"You mean, dogs are domesticated by these old, weak, sick and disabled wolves?"

"These wolves cannot hunt because of their own problems. If they want to survive, they must find new food sources to maintain their lives. In nature, what is the best food source for them?"

"The tribe of humanity."

"That's right." Chen Kan nodded.

Why do dogs eat bones? Because the structure of human teeth means that it is impossible for humans to really gnaw all the bones, and those wolves just eat these bones that were discarded by humans.

Of course, bones alone are not enough. First, the nutrition is limited, and second, the quantity is rare. After all, ancient humans could not have big fish and meat every day. Therefore, these wolves also need other sources of food. They need "food" that is both nutritious and abandoned by humans. This is obvious...

That's why Chen Kan said that dogs are actually wolfs that are domesticated themselves. In order to survive, it is entirely possible that in order to obtain a stable source of food, or not to be driven away by humans, those wolves take the initiative to become sentinels of humans, forming a relationship similar to symbiosis in the animal world.

Over time, if passed down from generation to generation, these wolves will lose their original wolf nature and dogs will appear.

Of course, this is not just Chen Kan's pure logical reasoning, but there is also some evidence to support Chen Kan's guess. There is a lot of evidence, and the best evidence is archaeological discoveries.

As mentioned before, if wolves want to find "food" abandoned by humans around human camps, then there must be a prerequisite, that is, humans have entered a relatively stable tribe settlement life, because only in this way can they provide wolves with a relatively stable source of food.

The earliest dog was discovered about 14,000 years ago. It was a dog's jaw bone. Of course, this is not a fossil, because there is not enough time and it cannot form a fossil. 14,000 years ago, it just corresponds to the period when human settlement life gradually formed.
