Sad news for fans of Jurassic Park - to recreate a park with prehistoric animals in real life is impossible due to the impossibility of cloning dinosaurs and other prehistoric creatures.
As the world media report today, Australian scientists have come to the conclusion that it is impossible to clone dinosaurs, since there is no material for obtaining DNA suitable for cloning and is unlikely to appear. Bone tissue (bones are a common find in such cases) has lost DNA for such a long time, from which cloning can be performed.
The withdrawal of scientists from Australia carries a strong blow to those who believed that their clones could be reproduced from the DNA of the discovered bones of prehistoric creatures in the future. At least not with dinosaurs. Perhaps scientists will have better luck with mammoths, because mammoth bodies are found in permafrost in a more complete form than dinosaur bones. But after all, mammoths that already live at the time of the appearance of man are not dinosaurs.
Through research, Australian scientists have found that the half-life of DNA molecules is 521 years - after this time, at a temperature of plus 13 degrees Celsius, the usable genetic material is halved. If the "material" is stored at a temperature of minus 5 degrees Celsius, then for 6 million 800 thousand years it completely becomes unusable, if we talk about the possibility of cloning, the media quotes the words of paleontologist Mike Bams.
As you know, dinosaurs became extinct 65 million years ago, so scientists have no doubt that their bones no longer contain genetic material suitable for cloning.
