The ancestor of the dog is the wolf, which is a more accepted theory in the current academic community, and the origin of the wolf can be traced back to 5 million years ago, but what is the origin of the wolf?

One theory is that all of today's mammals may have descended from the same ancestor, a small insect-eating creature that looked like a rat during the Cretaceous period. Sixty-five million years ago, at the end of the age of dinosaurs, these animals had the opportunity to evolve and diverge into the mammals of today's world.

Carnivores appeared about 60 million years ago in the Paleocene. The oldest carnivore is the little archaic cat, which, although called cats, is the common ancestor of all animals in the family of cats, canines, bears, mustels, hyenas, civets, and pinnipeds (a class of seals and sea lions).

About 48 million years ago, there were two types of cat suborders, the cat suborder and the canine suborder.

Originating in the late Eocene, about 40 million years ago, the canines were the oldest group of carnivores, first differentiated from the little archaic cats. The evolution of canines has three main lines, namely the three subfamilies of the canidae: the modern canine subfamily, the ancient canine subfamily, and the Borophaginae subfamily (hyena-like canids).

The ancient canine subfamily is an ancient branch of the canine family, which originated and developed in North America 40 million years ago, and they seem to be a cross between a fox and a weasel. About 15 million years ago, this branch gradually became extinct, and the genus Tong survived by evolving into today's subfamily Borophaginae.

The subfamily Borophaginae, on the other hand, emerged 34 million years ago. Like the ancient canine subfamily, they are found only in North America. They are much larger than the ancient canine subfamily, and their appearance is somewhere between that of hyenas and dogs, and they are characterized by a large, powerful mouth. Two and a half million years ago, this branch also became extinct.

The last branch, the modern canine subfamily, evolved into all canines today. This one appeared almost at the same time as the other two, but it did not flourish until fifteen million years ago, when the other two began to decline, and then began to grow. This subfamily was also found only in North America until seven million years ago, in the late Miocene, when it came to Asia via a land bridge.

Those who crossed the land bridge became the direct ancestors of the current canines, who continued to cross the land bridge and migrate back and forth between the two continents. This is why the red fox and the gray wolf are found in Eurasia and North America.

However, in Miao Pu's view, the mutant xenomorph in front of him is obviously not a simple atavism.

As far as he knew, even Dire Wolf (Canisdirus), a dire wolf that appeared 400,000 years ago, was quite different from the mutant species in front of him.

For example, dire wolves are known for their powerful mouths, and fossils suggest that they have very developed jaw tissue and an amazing bite force, which is more powerful than modern wolves. But the one in front of me is a small mouth, and the shape of the head is more inclined to a fox, which actually determines its hunting object, which cannot cover large animals such as wildebeest like wolves, but can only be small animals such as badgers and ferrets.

Of course, because its overall size is much larger than that of a fox, its proportionally enlarged mouth still looks quite impressive.

But don't forget, it doesn't correspond to ordinary animals, but to the disaster area, a special zone with a unique topography and ecological environment just like Australia in the past.

Here, even at the edge of the new forest, the oxygen content is twice or more than that of other areas, which fundamentally provides a basic guarantee for the growth of animals and insects. Coupled with a series of other reasons, the increase in size is basically a common feature of the disaster area, although it has not been seen as outrageous as the existence of dinosaurs, and it can be concluded that the animals have become more robust and more lethal, which is a very typical example of the disaster area.

Although the mutant xenomorph in front of him is not as strong as the ancient dire wolf, the partial fox may also be as good as the partial fox, perhaps its brain domain is more developed, and its IQ is higher.

In addition, another special feature of this mutation is that the legs of the xenomorph are very robust, which is beyond the proportion of all known canids, and slightly higher than that of cats such as lions and leopards.

After some observations, Miao Pu came to the following conclusions:

This process of change does have a tendency to atavism, but there is also obvious intervention of human adjustment. Miao Pu can only attribute it to an improvement in the program of setting up the bone nucleus. In other words, one of the original intentions of the bone nucleus he obtained was to strengthen the brain and limbs, the former referring to IQ and the latter representing motor ability.

From this, it can be explained to a certain extent that there is a certain amount of wisdom in why those giants have such strong bodies and extraordinarily thick and powerful limbs.

In fact, Miao Pu's experiment was more to gain an in-depth understanding of the role and function of the bone nucleus, and he was not even sure whether the implantation method he tried was correct.

As for the result, Miao Pu had already prepared for the worst, and he had no luxury of hoping to transform a certain type of biochemical weapon.

It's not that he doesn't dare to think about it, but he has realized the imperfection and complexity of this system. Compared with the research body, those giants may just be the result of painting cats and tigers, and the use of black energy can be said to be the way to go off the beaten path, which is far inferior to the research body's ability system similar to the awakened in Miao Pu's opinion, which can be felt just by looking at the results of the use of the insect queen and the explosion after the eyebrows are just implanted.

In fact, to Miao Pu's surprise, his core energy "Heart of Nature", that is, the balance system (including silver, nourishment, and life), can successfully expel and replace the black energy in the bone nucleus, which makes him feel a little incredible. After all, in his mind, black energy was a force that could successfully suppress the violent nature of wild energy.

What he didn't expect was that his core energy was superior to the black energy at its essential level. Black energy can suppress wild energy, and the reason why it can be suppressed is also for another reason, not that its essential level is better.

Even if Miao Pu's balance system has not yet been activated, and the power of the heart of nature has correspondingly not shown all its power, but he has fused the yin body of the insect queen with the yang body, which is equivalent to completing the research project of the secret research institute of the Fencheng Pharmaceutical Factory, even if it is still slightly different from the research body, but it is also based on the completion body.

Miao Pu's level is naturally much stronger than the derivative projects that are even second best on the basis of the research of the project, the black energy series.

While pondering, Miao Pu, who was studying and observing the mutation of wild dogs, suddenly changed slightly, and his eyes showed surprise.
