Dinosaur park is only in imagination

Australian scientists conclude that it is impossible to use DNA extracted from dinosaur fossils to regenerate dinosaurs, so dinosaur parks exist only in sci-fi movies.

Scientists at Murdoch University (Australia) say that DNA cannot survive more than 6.8 million years in fossils, so it is impossible to successfully carry out fossil DNA extraction experiments to recreate dinosaurs. , while they were extinct 65 million years ago, according to the Sydney Morning Herald on October 12.

Lead researcher Dr Mike Bunce said the team came to a conclusion after studying fossil bones of an extinct bird in New Zealand 521 years ago.

They extracted a piece of DNA from this fossil and stored it at 13.1 degrees Celsius, but when the temperature dropped to 5 degrees Celsius, the DNA completely disappeared.

Dr. Bunce said DNA could only last about one million years in dinosaur fossils if stored under ideal low temperature conditions.

Scientists around the world have long been trying to study whether DNA after dinosaur fossil extract can be used to recreate dinosaurs, like in literary and Terrible Park movies. long (Jurassic Park).

'In the early 19th century, many scientists were very curious about creating a dinosaur park. But creating a park with live dinosaurs recreated from fossil DNA is impossible in practice, 'said Dr. Bunce.

The study was published in the scientific journal Proceedings of the Royal Society B.
