If the dinosaurs were to be resurrected, would it be a good thing or a disaster for humanity?

If the dinosaurs are resurrected, it is always said that there are advantages and disadvantages for us humans, the advantage is that we can see the real dinosaurs, and the disadvantage is that we have another threat outside, and if there are a large number of dinosaurs, it is not convenient to control.

01. The benefits of dinosaur resurrection. Dinosaur resurrection is a certain benefit, after the resurrection of dinosaurs, we can see living dinosaurs, no longer only see fossils, after we go out to play and have one more place to play, go out to see dinosaurs, I believe that seeing dinosaurs can give us a great shock, Tyrannosaurus rex.

Pterodactyl, Canglong.

All are resurrected, and the overlord who once ruled the earth for hundreds of millions of years is back.

02. The disadvantages of dinosaur resurrection. The resurrection of dinosaurs will also have a lot of disadvantages for us, first of all, how to manage these dinosaurs? If it is not managed well, it will be a disaster for humans, and the size of the dinosaur is nowhere to put it, so take the triceratops.

It is more than 20 meters long, this length is really terrible, a tail past a building is gone, and the dragon, the overlord of the ocean, when the ship with a small size is swallowed directly, these dinosaurs basically have no opponents on the earth, so the diversity of the earth's life will face a big problem.

03. The resurrection of dinosaurs does more harm than good. The resurrection of dinosaurs must do more harm than good, the current environment dinosaurs are no longer suitable for appearing, and people will not allow dinosaurs to appear, take a look at Jurassic Park

What a disaster the management of dinosaurs has caused, and now our cloning technology.

It's already very advanced, and if a dinosaur wants to be cloned, as long as it has DNA, it's not that difficult, so why not clone it? The main reason is what to do with cloned dinosaurs? There's nowhere to put it.

Summary: Dinosaurs are no longer suitable for this era, let's let them disappear with the times, sometimes disappearing is a good thing, after all, it is precisely because dinosaurs disappeared that we can have so much curiosity about them, with dinosaurs, it is not necessarily a good thing for us.

It was a disaster, because the size and strength of the dinosaurs would pose a huge threat to humans, and their feeding ability was also very terrifying.

Disaster. Dinosaurs were carnivores and much larger than humans, and if the dinosaurs were resurrected, then humans would be miserable.

Dinosaurs are the overlords of the past, human beings are the overlords of the present generation, the so-called one mountain does not tolerate two tigers, two tigers must fight for one injury, if it is resurrected, disaster will follow.

If the resurrection of the dinosaurs, the overlord of the earth, what will be the impact on us humans? Will humanity become extinct.

Dinosaurs have been extinct for too long, and there are no genes suitable for breeding, and there is no way to see dinosaurs resurrected in the future. The topic of resurrecting dinosaurs has never stopped, and even many people think that dinosaurs will really appear in the future, but scientists have actually explained that dinosaurs are difficult to resurrect; Dinosaurs have been extinct for a long time, and DNA loss is more serious, so it is difficult to truly resurrect dinosaurs without a suitable environment for breeding. Resurrected dinosaurs can only appear in movies, and resurrected dinosaurs will not be seen in the future.

1. Dinosaurs have been extinct for a long time, and the preserved DNA basically cannot be directly activated, and it is impossible to resurrect dinosaurs

Dinosaurs have been extinct for 65 million years, and although many amber-protected dinosaur bones have been found on the archaeological road, it is difficult for dinosaur DNA to reappear in the world; Genes have an expiration date, generally more than 500 years without much value, and there is almost no complete dinosaur gene in history, indicating that dinosaur genes are difficult to be truly activated. Some scientists once tried to clone dinosaur genes, but unfortunately there was no news after many years to prove that the genes could not be resurrected.

Second, even if DNA can be activated, it is impossible to find suitable genes for breeding, and the dream of resurrecting dinosaurs is actually difficult to realize

Even if scientists do succeed in replicating dinosaur genes one day, they will not be able to resurrect dinosaurs without suitable breeding genes; The resurrection of any animal requires two factors, genes and breeding genes, dinosaurs have long disappeared from the earth, and there is no similar breeding gene at all, even if their genes are activated, they cannot find a place and genes that can be cultivated. In the movie, eggs are used to breed dinosaurs, but can reality do it? No, because evolution has caused eggs to no longer adapt to dinosaur genes, and it is impossible to resurrect dinosaurs through eggs.

Humans can't resurrect dinosaurs, so we won't see dinosaurs breathing on Earth in the future.

If the resurrection of the dinosaurs, the overlord of the earth, what will be the impact on us humans? Will humanity become extinct.

With the development of technology, I think that humans can eventually resurrect dinosaurs, but it is obviously impossible to do this with recent technology.

It is estimated that the real resurrection is not possible, but it is possible to return some existing species to the state of the dinosaur period and achieve the effect of pseudo-resurrection.

In the near future, humans will not be able to resurrect dinosaurs, because dinosaurs are extinct, and no one knows if dinosaurs really have corpses.

1. No, you can't. 2. Dinosaurs are extinct: Dinosaurs suddenly disappeared at the end of the Cretaceous period 65 million years ago, becoming a mystery in the history of the evolution of life on earth, which is still unsolved.

All of the earth's past creatures are recorded in fossils. In the strata of the Mesozoic Era, many dinosaur fossils have been found in the god Zengpang. A large number of bones can be seen in a variety of shapes.

However, in the Cenozoic strata that followed, there were no fossils of non-avian dinosaurs at all, which suggests that non-avian dinosaurs became extinct together during the Mesozoic.

3. Can't be cloned: Scientists need DNA to clone dinosaurs, but DNA begins to decompose after the organism dies. This is the result of the action of enzymes (from soil microorganisms, somatic cells, and gastrointestinal cells).

Ultraviolet radiation also breaks down DNA. In addition, oxygen and water can also change the aging properties of DNA, causing the double helix chain to break. It breaks down the DNA into smaller, finer-fragmented fragments until eventually nothing is left.

If you can't extract DNA, you can't clone dinosaurs.

How did the dinosaurs that ruled the earth for hundreds of millions of years get rid of it?

The cause of the extinction of the dinosaurs was more than 100 theories, such as the theory of rock impact, acid rain, and climate change. One of the most favorable is the meteorite impact theory. It was a meteorite bigger than a city that crashed into Mexico, causing the air to turn into dust, the sun not visible, plants withered, herbivores starved, and carnivores died.

When the dust buried the dinosaurs in the ground, it also wiped out 75% of all living things on the planet. Scientists say it is impossible to resurrect dinosaurs because their genes have been damaged for hundreds of millions of years.

1. Reasons for the extinction of dinosaurs:

Causes of Dinosaur Extinction Dinosaurs disappeared 65 million years ago during the Cretaceous-Tertiary extinction event, along with the extinction of many other organisms, including ammonites, cangosauridae, plesiosaurs, pterosaurs, herbivorous turtles and crocodiles, most birds, and primitive mammals [11]. Since the 1970s, there have been many studies that have attempted to explore the causes of this extinction event and have developed several theories.

The usual explanation is that an impact event caused the extinction, with some scientists suggesting other reasons, or a combination of several events that led to the extinction.

The dinosaurs went extinct 65 million years ago. And at that time, not only were all the dinosaurs that had ruled the earth for more than 100 million years extinct, but the same tragic fate befell many other creatures living on the earth's land, sea, and sky.

2. Can dinosaurs be resurrected?

A: The current level of science and technology is really insufficient.

If you want to resurrect dinosaurs, you would theoretically need to extract dinosaur genes from fossils, and then inject some of the genes into the fertilized eggs of specific creatures, such as the fertilized eggs of some reptiles, through biological means. Then a class of creatures was cultivated, and some genes were added to the fertilized eggs of such creatures until they gradually approached the dinosaurs we know.

Again, the current level of science and technology is really not enough.

It may be that after decades or hundreds of years, the technology has reached and the dinosaurs will indeed be able to resurrect, but by that time, I am afraid that all kinds of strange creatures will have emerged one after another.

It can only be said that the future is bright, but the road is still bumpy.

The resurrection of the dinosaurs depends on whether we can recover the intact DNA of those lives that died more than 65 million years ago, which is probably impossible now. Although soft tissue has been found on the inside of the thigh bone in some dinosaur fossils, so far we have never succeeded in extracting DNA using this method, only protein. Although these proteins have been able to chemically prove that dinosaurs have a close relationship with species such as frogs and chickens, there is still a long way to go before reconstructing the genome of dinosaurs.

However, Dawkins said there are still possibilities. He proposed that we could genetically compare the genomes of various birds and reptiles, and then mathematically reconstruct the DNA order of "generalized dinosaurs". This, he notes, may induce a chicken's beak to grow a tooth root (or a snake to grow legs), as it is possible that ancient traits that have long since disappeared into the quicksand of time are still present in the genome.

His statement represents a perception among biologists today. In the long evolution of species, genes can be turned on or off. This means that the genes of the ancient traits may still be there, just dormant.

By opening these long-dormant genes, it may be possible to reclaim the characteristics of these ancient species. For example, in ancient times, chickens' feet used to be webbed. The genes associated with webbing have not disappeared, they have just turned off.

By turning on this gene, it is, in principle, possible to produce chickens with webbed feet. Similarly, people used to have hair on their bodies. However, when we start sweating in order to effectively regulate the body's body temperature, we lose our long hair.

Dogs have no sweat glands and can only be cooled down by panting. The genes associated with human hair are apparently still there, just turned off. However, if you open this gene, you may be able to breed people with long hair all over their bodies.

Some speculate that this may be the reason for the emergence of werewolf legends. They say, since birds are the only animals on the dinosaur tree that haven't gone extinct, why can't we flip some switches in the genetic code and let chickens recreate the glory of dinosaurs?

If we assume that some of the dinosaur genes were actually turned off for millions of years but still survive in the bird's genome, then it may be possible to restore the activity of these long-dormant genes and induce dinosaur traits in the bird. In this way, Dawkins's suggestion, while speculative, is not nonsense. In fact, as recently as early May 2015, scientists announced that they had modified the embryos of chickens to make their beaks resemble those of the ancestors of birds, dinosaurs.

Currently, Jack Horner, who is leading the project, and his colleagues are currently working on getting chickens to grow long tails – what some consider to be the most complex step in creating a "chicken dinosaur". They tried to find a genetic pathway that blocks tail development by performing genetic screening on mice. These findings can help them find ways to turn on the "switch" on tail growth.

Maybe when the day comes when the chickens grow their tails, we will not be far from the resurrection of the dinosaurs.

Scientists: Genetic information has been "invalidated" Dinosaur resurrection is impossible.

According to Singapore's Lianhe Zaobao14**, modern genetic and cloning technologies are developing rapidly, and even extinct prehistoric animals may be resurrected in the future. However, scientists point out that it is impossible to resurrect dinosaurs, which became extinct 65 million years ago.

According to the Sydney Morning Herald, the British magazine New Scientist has a list of ten prehistoric animals that are most likely to be resurrected through genetics and cloning. However, the magazine noted: "Dinosaurs have no chance of resurrection, and other extinct animals may reappear on Earth." ”

Because DNA begins to break down after the death of organisms and is destroyed by sunlight and bacteria, the only animals that may be resurrected using cloning technology are animals that have become extinct in the near future, the report said. "No genetic information could have been preserved for more than 1 million years, so it is impossible for the dinosaurs to be resurrected," the report noted.

Schuster, a molecular biologist at Pennsylvania State University in the United States, said: "What is really worth studying is the [genetic] sample that is less than 100,000 years old." ”

Some scholars disagree.

However, Archer, dean of the Faculty of Science at the University of New South Wales in Australia, was very unimpressed with the statement of "New Scientist". He argues that the magazine's view was too pessimistic and "completely missed the point" because the living dinosaur genes are all around us.

"I'm surprised that birds don't think of birds as dinosaurs, they carry dinosaur genomes," Archer said. He points out that in the course of evolution, many of the birds' genes, including those for the development of claws and scales, have changed or fallen asleep, so that they no longer look like the dinosaurs in the book.

"We need to understand how to turn on these genes, which are waiting to be activated," Archer said. He believes that the first resurrected dinosaur might look like a five-kilogram "chicken from hell."

Archer**, the first prehistoric animal to come back to life would be a mammoth. Scientists have deciphered most of the mammoth's genetic structure last year. "I would be very surprised if the mammoth hadn't been resurrected in 20 years," he said. ”
