Jurassic Park proved 'impossible' by DNA research

'Jurassic Park' will never become a reality thanks to new DNA research, it has emerged.

Palaeogeneticists from the University of Copenhagen and the University of Perth in Australia have discovered that DNA has a half-life of 521 years, after studying the leg bones of giant extinct birds called moa in New Zealand.

The discovery means that the material would have degraded long before it could be sucked out of a blob of amber, as fictionalised in Steven Spielberg's film and Michael Crichton's book.

Even in perfect preservation conditions, DNA will become 'unreadable' after 1.5 million years, making hopes of a deadly tropical theme park a tragic impossibility.

“This confirms the widely held suspicion that claims of DNA from dinosaurs and ancient insects trapped in amber are incorrect,” said Simon Ho, a computational evolutionary biologist at the University of Sydney, to science journal Nature.

Advances in reading DNA would not help either, with every nucleotide bond in a DNA strand having broken down by 6.8 million years.

Sadly, the last of the dinosaurs died out around 65 million years ago.
