For all kinds of creatures related to the blood of dinosaurs, it is a gauge of measure! Whether it is an ancient dinosaur or a modern creature. In general, the higher the brain quotient, the smarter the dinosaur.

Based on this data, paleontologists found that the brain quotient of carnivorous dinosaurs was generally higher than that of herbivorous dinosaurs, and that the brain quotient of small carnivorous dinosaurs was higher than that of large carnivorous dinosaurs!

The brain quotient of sauropod dinosaurs was only 0.2 to 0.35, the brain quotient of ankylosaurs was only about 0.52, the brain quotient of stegosaurus was about 0.56, and the brain quotient of ceratosaurus was about 0.7 to 0.9.

The IQ of the Wounded Tooth is the highest, reaching 5.3! This brain IQ level is many times that of the Tyrannosaurus Rex! Such a Wounded Tooth is already smarter than any living reptile or some mammals! This kind of IQ is nothing in the eyes of today's biological world.

However, 65 million years ago, it was the best of the best! At that time, the ancestor of mammals, the distant ancestor of mankind, had an IQ not much different from that of a mouse today. Far worse than the Wounded Tooth Dragon.

After all, in the era when the Toothless Saurus was in power, the ancestors of today's birds, such as the Archaeopteryx and the Golden Phoenix, had a negligible IQ in front of the Toothless Dragon.

Even, the golden phoenix bird is a kind of wounded tooth dragon.

But only birds, because of their small size and ability to fly, have escaped the catastrophe of heaven and earth six days and five million years ago and survived to this day. Therefore, through the study of the IQ of birds today, we can roughly judge how high the IQ of the Wounded Tooth Dragon would have been if it had not become extinct.

According to biologists, many birds, such as blackbirds, shrikes, and parrots, can mimic the calls of other birds or even human speech. And the most intelligent crow birds, such as crows and magpies, have good learning and memory skills, have complex social behaviors, can work together to forage for food, and they can even learn to use tools to obtain food.

Crows learn to put walnuts on the road for cars to crush, and then fly down to peck at walnut flesh when the red light is on. Magpies are able to recognize themselves in the mirror.

Over the course of their long evolutionary process, the brain-to-body ratio of these birds is similar to that of chimpanzees and only slightly smaller than humans. The African grey parrot is not only able to imitate human accents. Even be able to relate words to their meanings and organize short sentences on your own!

Once upon a time, there was an African grey parrot named Alex, who was able to distinguish between more than fifty things, seven colors, five shapes, and a value of six. And understand the difference between big and small, up and down!

This IQ is already better than that of many cats and dogs! It is similar to that of a child about five years old.

In the IQ ranking of creatures in nature, birds occupy three places!

If it weren't for the modern birds, they suffered too small a loss. Modern birds are the size of humans. Or almost. And maintain the body-to-brain ratio. In other words, the size and capacity of the brain are about the same as the size of a human being, and the ratio of the brain to the body is about the same as that of a human being.

So, how much less intelligent will such birds be born than humans? Or because of their sufficient intelligence, these birds can create their own language, their own civilization?

The IQ of an adult chimpanzee, which is comparable to that of a human-sized child, is already comparable to that of a mentally handicapped child in humans. The most intelligent individuals are capable of IQ as human children as they are ten years old. In other words, the upper limit of its IQ can already reach the lower limit of human IQ.

So, should such creatures be called animals or people?

If a bird with a completely different path of evolution from that of humans and mammals evolves to this extent, can it be called a birdman?

After 65 million years of evolution, the IQ of these birds will be inferior to that of humans who have only evolved for millions of years.

Or, because it has tens of millions of years of evolutionary process than humans, it will have a higher IQ?

Therefore, some paleontologists are confident that the odontosaurus would have evolved into intelligent life if it had not gone extinct. However, although this matter is supported by various rigorous scientific research data, the results of the research are convincing. However, the results of this research have no commercial use for human beings at all!

It has no impact on people's lives. Even if it was the 65 million-year-old Wounded Tooth Dragon, if it didn't die, it could evolve into an immortal, and it had nothing to do with ordinary human hair. Anyway, say a thousand ways and ten thousand, the existence of such a bull fork has become extinct.

Only those who are interested in paleontology, the billions of years of biological evolution on Earth, will pay attention to the results of these obscure studies.

Therefore, Yun Lei knows about this matter of fear, but Rao Ya does not know.

Yun Lei heard the leading tooth-wounded dragon, like a parrot, and felt a little funny in his heart. This is a distant ancestor of birds, which is related to the scarlet tooth, and its voice is really like a bird's call. However, it is different from the bird's call. In the seemingly unanimous sound, there are obviously many syllables! obviously, very rhythmic.

Yun Lei sighed slightly, it seems that although the remnants of these toothed dragons are trapped in this underground space, they have evolved very slowly. Although it was tens of millions of years earlier than the evolution of human beings, until now, the degree of evolution is only equivalent to the primitive civilization of human beings.

The gap between us and human civilization is at least 10,000 years! The difference in strength between us and human civilization is simply a world of difference. If human civilization wants to exterminate these terrorists, it only needs to find a few soldiers who are fully armed and equipped with modern equipment, and then these terrorists can be exterminated.

These terrorists still have a long way to go to catch up with human civilization. There will be no real threat to humanity at all!

However, Yun Lei did not dare to slack off. He didn't come to exterminate these horrific people! Instead, he lowered his head and took out some of the food he had stored on his private planet from the space gourd. In addition to grains such as rice and wheat, there are also a variety of delicious biscuits and pastries, as well as beef and mutton jerky.
