Tyrannosaurus rex was extinct tens of millions of years before we humans appeared on the earth. It is unlikely that we will see tyrannosaurus again in the foreseeable future. Unlike the basic idea of the movie, scientists are very sure that we cannot clone it yet. Dinosaur. The biggest reason is that dinosaur DNA has not been preserved.
There are many practical obstacles to cloning dinosaurs
Professor Barrett said: "As far as we know, DNA has not been preserved for a long time."
"The oldest DNA in the existing fossil record is about 2 million years old, and it is just DNA fragments from bacteria, soil, fungi, etc. As far as animals are concerned, the oldest existing animal genetic data is about 50,000 years ago. of."
"As far as ancient organisms go, we don't have DNA from any extinct animals or plants, so I don't think it can be done."
DiGiacmo agrees, saying that even if there is a major scientific breakthrough in dinosaur genetics, it does not mean that dinosaurs can be cloned. “There are so many uncertain variables involved in cloning a species that is so geologically distant that it is extremely complex.”
She also raised questions about potential ethical issues. "Movies like 'Jurassic Park' tell us not to do this, otherwise humanity will suffer, and what does it mean for them to bring distant ancient creatures into the modern world?"
