Resurrect dinosaurs with DNA? Give Me A Break

From Jurassic Park to Jurassic World, these series of movies show us the ancient creatures we are most interested in – dinosaurs, and the recent Jurassic World 2 has ignited everyone’s interest in dinosaurs, again. In real life, many children may have thought: can we build a Jurassic theme park like the one in the movie? it would be great to see the real dinosaurs with your own eyes! So, it is possible to build such a Jurassic Theme Park in real life? Let’s take a look at these ancient bioscience sci-fi movies and check it out.

How the paleontology theme became popular

In many people’s opinion, the top movie of sci-fi movies of aerospace are likely to be “Star Wars” and “Star Trek” series, and the sci-fi movies of the ancient creatures are only the “Jurassic Park” and “Jurassic World” series. .

Since the release of the first Jurassic Park in 1993, four Jurassic Park films have met the reverie “dinosaurs resurrection” of dinosaur fans around the world, and have profoundly affected our real life. Even a piece of amber wrapped in insects from the Jurrasic era, or a dinosaur egg fossil with an unidentified paste inside, will lead to a lot of reports from various media, because people believe that it may be the “key” for the dinosaur to return to the earth. .In 1985, the United States proposed the “Human Genome Project”. After mastering the technologies of nuclear, space flight and landing on stars, scientists begin to use the biological and chemical achievements at the forefront of the time, trying to draw the human genetic map.

This great scientific research project comparable to the US military weapons program “Manhattan Project” and “Apollo Moon Landing Plan” during the Second World War, led to the development of many fields of life sciences.

Perhaps it was inspired by the development of life sciences, some forward-thinking people began to think about the possibility of “resurrection” of extinct animals and even artificial life. In 1990, Michael Clayton created “Jurassic Park” in this context. It also became a bestseller because of the “dinosaur fever” popular in American at that time. Then the film is also a matter of course.

Can the dinosaurs be resurrected?

Movies like this are so hot, they also give fans a lot of expectation, but regarding today’s life science knowledge, they have some hard-to-avoid issues when talking about the science truth. For example, according to the film Jurrasic Park, “The genetic material used in the dinosaur resurrection was derived from the dinosaur blood that remains in the body of a mosquito, and the ancient insect came from the amber produced in the Dominican area. In the Jurassic World’s visitor centers and research institutes, a large number of ambers are also set up to remind that the park operators “how did this start”.In fact, in the 1990s, many people believed that amber was the perfect “wrap film” that allowed the animal genetic material to reach modern times across tens of millions of years.

But the facet may let you down, because modern life science research has proven that the half-life of DNA is 521 years. That is to say, every 521 years, the chemical bond between deoxyribonucleotides is broken by half. Even if the genetic material is stored under the optimal conditions of minus 5 degrees Celsius, it can survive at least 7 million years. In fact, after only about 1.5 million years, these chemical bonds will be broken and completely unreadable. As we all know, the last batch of dinosaurs disappeared 65 million years ago. Therefore, it is impossible to resurrect dinosaurs in this way. According to the current life science knowledge, we can only see these lifelike dinosaurs in the film and television such as Jurassic World and Jurassic Park, or find the animatronic dinosaurs out in Jurassic theme parks or natural history museums.
