Review
In the long 4.6 billion years of Earth's history, there is a creature that has been at the top of the food chain for 160 million years, and is famous for its unique appearance and full dominance over other creatures, and many film and television literary works have been based on this creature, which is a dinosaur. Although these beasts have been extinct for 65 million years, they have undoubtedly spent a long time on Earth. The most impressive among the dinosaurs should be the ferocious Tyrannosaurus rex, and many modern people will also ask the question, if the earth is really like "Jurassic Park", suddenly 58 million Tyrannosaurus rex, what will happen to human beings?
The terrifying Tyrannosaurus Rex
Tyrannosaurus rex has been at the top of the food chain since its appearance, and its height can reach more than 4 meters, and its body length is more than ten meters. Such a size is undoubtedly very terrifying, now any kind of terrestrial creatures on the earth are not so huge size, the weight of the Tyrannosaurus rex can be as high as nearly 10 tons, their forelimbs are short, but the hind limbs are extremely developed, can support the Tyrannosaurus rex to run at a very fast speed, the bite force of the Tyrannosaurus rex has reached 6 tons, can effortlessly bite the human family car. In the era when the dinosaurs were not yet extinct, Tyrannosaurus rex was undoubtedly the master of all living things on earth.
However, Tyrannosaurus rex has a skill, but does not have the brain to evolve, so in the face of the meteorite attack 65 million years ago, Tyrannosaurus rex also disappeared into the long river of history like all other dinosaurs, leaving only some fossils for humans to study. At present, human beings can only study and investigate the biological characteristics of Tyrannosaurus rex through fossils, and there are no more Tyrannosaurus rex-like creatures in the world.
Interesting assumptions
Someone has put forward an interesting hypothesis based on T. rex, if there were 58 million Tyrannosaurus rex suddenly emerging in the world, what kind of impact would our human society be affected? After all, the Tyrannosaurus Rex was huge and destructive. Two or three-story bodies can easily destroy buildings and vehicles, and ordinary people seem helpless when facing tyrannosaurus rex. However, the truth is not so simple.
First of all, Tyrannosaurus rex is a prehistoric creature, their physical functions are unable to adapt to the current environment, in the period of life of the Tyrannosaurus rex, the oxygen content on the earth is extremely sufficient, the carbon dioxide content in the air is also high, and the climate is quite warm. So if Tyrannosaurus rex and former bodily functions appear in the current society, they will face a series of problems, such as insufficient oxygen supply, hypothermia, and even basic life cannot be maintained, let alone the destruction of human society.
And even if Tyrannosaurus rex can ignore the environmental conditions and maintain its original vitality in human society, we humans do not have to worry too much, because under the current social system, if a large number of tyrannosaurs suddenly appear on the earth, the armies and police of various countries will bear the brunt of hunting and capturing these creatures that may threaten the safety of residents. Although the T-Rex can reach a speed of nearly 40 kilometers per hour, the speed of any police car can easily break through 100. Therefore, in terms of speed, the Tyrannosaurus Rex is no better than humans with modern technology.
And human beings in the long process of development learned to use firearms, take the most famous Barrett sniper rifle, such sniper rifle is very powerful, can be a shot on the scrap of communication wires or ammunition depots and other military facilities, although the Tyrannosaurus rex is huge, the skeleton is harder, under such a powerful firearm, but there is no way. So if there really is a T-Rex on Earth, we ordinary people just need to hide in our homes and wait for the military personnel to take control of this dangerous creature.
The conquest of other creatures by humans
Since humans mastered the ability to use tools, they have been at the absolute top of the food chain, and more than 10,000 years ago, our ancestors were primitive people, and they could only use wooden or stone weapons to hunt other creatures. Under such conditions, we humans can catch a giant like a mammoth.
Then it is very simple to integrate the control or killing of Tyrannosaurus rex with the current human technological means and social system. Therefore, all kinds of evidence shows that even if tens of millions of Tyrannosaurus rexes do appear on the earth, human civilization will not be greatly affected, but if this kind of thing really happens, we should be able to see this amazing creature in the zoo or at the dinner table in the future.
Feasibility of dinosaur cloning
Ever since the advent of dolly the cloned sheep, people from all walks of life have been paying attention to human cloning of prehistoric animals, after all, this is an opportunity to make prehistoric creatures come to life. But it is a pity that human beings cannot clone such creatures as dinosaurs with current human technology. Because we lack the direct DNA of the dinosaurs, as a creature that has been extinct for 65 million years, the flesh and blood of the dinosaurs have disappeared on the earth, leaving only fossils without DNA.
This is because the DNA chain has a half-life, and the chemical chain of DNA is halved every 521 years, so when facing these prehistoric animals, it is impossible to extract any DNA with current human technology, and it is naturally impossible to successfully clone.
epilogue
Although dinosaurs are an animal that has been extinct for a long time, their former existence has also brought a lot of after-dinner talk to the current human beings. Perhaps one day in the future, science and technology will be further developed, and humans can overcome the barriers of cloning technology. By cloned millions of years ago fossils of these creatures that once dominated the earth, we modern humans can also understand the long history of the earth in a more intuitive way.
