An Australian Jurassic Park?

Rumors are circling that an Australian billionaire wants to create a Jurassic Park. Could it actually work?

One of the reasons Jurassic Park was so successful–as a novel and a blockbuster film–is that it presented a plausible way to bring dinosaurs back to life. The idea that viable dinosaur DNA might be retrieved from bloodsucking prehistoric insects seemed like a project that could actually succeed. Even though the actual methodology is hopelessly flawed and would never work, the premise was science-ish enough to let us suspend our disbelief and revel in the return of the dinosaurs.

Nevertheless, Jurassic Park brought up the tantalizing possibility that scientists might one day resurrect a Brachiosaurus, Velociraptor or Triceratops. And every once in a while, rumors arise about someone who might just give the project a try. According to the latest round of internet gossip, Australian billionaire Clive Palmer is hoping to clone a dinosaur for an exotic vacation retreat. Palmer has since denied the rumors, but, for a moment, let’s run with the assumption that someone is going to pour millions of dollars into a dinosaur cloning project. Would it actually work?

As Rob Desalle and David Lindley pointed out in The Science of Jurassic Park and the Lost World, there were a lot of steps that Michael Crichton glossed over in his dinosaur cloning regime. The novelist never explained how scientists overcame issues of genetic contamination, figured out what a complete dinosaur genome should look like and, most important of all, figured out how to actually translate all that DNA into a viable dinosaur embryo. It’s not simply a matter of accumulating DNA pieces until scientists have mapped every gene. A creature’s genetics must be read and interpreted within a biological system that will create an actual living organism. There are innumerable hurdles to any speculative dinosaur cloning project, starting with the effort to actually obtain unaltered dinosaur DNA–something that has never been done, and may never be.

If Palmer, or anyone else, wants to create a dinosaur park, it would be far easier to set up a reserve for living dinosaurs. The cassowary–a flightless, helmeted bird–is sufficiently prehistoric-looking to make it a draw for visitors. True, it’s not a Velociraptor, but a cassowary is most certainly a dinosaur that does pack a mean kick. There are plenty of living dinosaurs that could use a hand through conservation programs, so perhaps it would be better to try to save some avian dinosaurs rather than bring their non-avian cousins back from the dead.
