Jurassic Park-Science Fact or Hollywood Science Fiction?
Steven Spielberg’s successful sci-fi adventure film tells two dinosaur experts—Allen and Dr. Ellie Sutler—at the invitation of the eccentric millionaire John Hammond to visit The story of his new playground on the outer islands of Costa Rica that is not yet open to the public. By cloning DNA extracted from prehistoric mosquitoes, Hammond created a living dinosaur for his new Jurassic Park.
Accompanied by Hammond's two grandsons, they were sent to a computer-controlled car for a trip around Jurassic Park. But a tropical storm hit the island, destroyed the electricity supply, and an employee breached the security system in order to steal the dinosaur embryos to sell, and the dinosaurs began to get out of control...
In this way, since sheep can be cloned, is it possible to clone dinosaurs? Or is this just a Hollywood science fiction movie? First, any DNA taken from a preserved mosquito is only 40 million years old. Dinosaurs are at least 60 million years old, so even if any DNA is found, mosquitoes need to be older, and as far as we know, mosquitoes that are so old do not exist.
Second, even though it is possible to find a preserved mosquito, only one male mosquito was found. In fact, only female mosquitoes can absorb the DNA of another organism. Moreover, it is impossible to know whether this DNA comes from dinosaurs. Since there are no previously discovered dinosaurs, they cannot be compared with new samples.
Third, after being extinct for so long, the DNA of dinosaurs will not be intact. When life is over, DNA breaks down and cannot repair itself.
Many problems also arise in the process of cloning dinosaurs. Some questions are: What needs to be done to successfully raise a small dinosaur? What conditions do dinosaurs need to survive? What do dinosaurs eat? What kind of care do dinosaurs need in adult life? What should be done to protect humans from dinosaurs or to protect dinosaurs from humans? What kind of moral and human rights issues will cloning bring?
Therefore, cloning dinosaurs seems impossible in a scientific sense. The world is unprepared for this, and the required material materials are not available. Even if it is really possible to bring dinosaurs back to life, they may not be able to survive in the current environment. The current temperature, air, diseases and plants are also completely different from those of the dinosaur era. Dinosaurs are used to a world completely different from here, and will find it difficult to survive here. Today, the only place where dinosaurs can survive seems to be Hollywood.
I saw this article in high school English textbooks, and it feels quite interesting. share.
