    We all want to believe that dinosaurs can one day roam the Earth once more, however how scientifically sound is this Hollywood sci-fi?

    Can science fiction become science fact?

     

    So lets back track a bit to 1993 when the first Jurassic Park was released. The science behind the first three Jurassic movies based on the book of the same name sake by Michael Crichton is completely inaccurate scientifically. Basically you take a mosquito trapped in amber (fossilized tree sap), extract the blood from its gut, assuming it has snacked on a dinosaur before becoming trapped in the amber, pull the DNA from the blood add in some frog DNA to make up for the loss in genetic material, and voilà you have a dinosaur. There are a few problems with this theory.

    Firstly, the DNA would not survive that long before decomposing, even if its incased in an amber preserve. DNA has a predicted life span of about a million years (depending on the environment of the fossil), dinosaurs became extinct 66 million years ago, so that’s a bust.

    Secondly, it would not be pure dinosaur DNA but more of a culmination of mosquito and dinosaur genetics.

    And thirdly, the use of a frog to complete the genetic code when any type of bird is the closest living relative today.

    Scientifically all this is not plausible, however there is some hope with the reboot of the franchise with Jurassic world and Jurassic World: Fallen Kingdom. Palaeontologists state that instead of trying to recreate the previous dinosaurs that roamed the Earth, it is probably easier to create genetic hybrids instead. Splicing genetics to create a completely new species like the franchise did with the Indominus Rex in the reboot Jurassic World.

    We, however, have a hurdle even with that, as we don’t have any base samples to use from dinosaurs, we only have bones in which the DNA had already degraded to a point where there are no traces of genetic material present within the bone.

     

    The fact of the matter is that we are no closer to changing the status of turning this science fiction into science fact, but we can still dream. And this new Hollywood blockbuster can keep those dreams alive, with belly clutching comedy, heart pounding action, a few tears shed and in true Jurassic Park fashion will leave you scared out of our wits, stuck between wishing it could never come true and secretly hoping that it might just become reality.
