Jack Horner is co-author of the bookHow to Build a Dinosaur. However, he is most famous for his role as consultant(顾问) on all four Jurassic Park films, including the new filmJurassic World.
The original filmJurassic Parktells the story of a theme park where dinosaurs live. In that movie, scientists used DNA collected by ancient mosquitoes that had been trapped in amber shortly after they drank dinosaur blood. The scientists used this dinosaur DNA to create baby dinosaurs. The scientists inJurassic Parkcreated various types of dinosaurs, but in the real world there is one big problem with the story. It turns out that DNA could not possibly survive the 65 million years since the death of the dinosaurs.
The new movie creates the Indominus Rex. This idea of creating a hybrid species is something Horner has explored before. In 2011, he gave a speech in which he discussed producing a dinosaur by working with the genes of a bird. Modern birds are the closest living relative of dinosaurs.
The concept of using the genes of different animals to create new animals is called transgenic science. And this type of science has already produced some interesting results — goats that produce spider silk in their milk, cows that produce proteins for medicines that can treat diseases, and a pig that produces less-polluting waste thanks to a bit of mouse DNA. However, none of these examples are close to the dinosaurs inJurassic World. And for a good reason — genetics is a very complex science. Producing a new species is not as simple as just exchanging a few genes around.
In the end,Jurassic Worldis all about fun.
