While the T. rex ruled the dinosaur food chain in the original Jurassic Park, the new genetically altered Indominous Rex appears to be on top in Jurassic World. The dinosaur with hybrid DNA is meant to be more powerful, faster, and more gruesome than its predecessors, which is unfortunate because the Indominous is also more scientifically a possible creature than its fellow dinosaurs.

Speaking to the BBC, paleontologist Jack Horner, who has served as an advisor to all four Jurassic films, said that the science behind the Indominous is actually “scientifically more plausible” than the science behind the original creation of the dinosaurs in Jurassic Park.

“The cool thing about making a hybrid is that we can take a whole bunch of genes from other animals and mix them together to make a new animal, which is actually more plausible than bringing them back,” Horner said.

And even though hybrid genetics already exist, the same problem that prevented Jurassic Park‘s dinosaurs from becoming a reality is the same one plaguing Jurassic World (though probably saving humanity).

“We don’t have dinosaur DNA but we can make transgenic animals,” Horner said, putting any fears to rest that the (clearly fiscally irresponsible) creation of a dinosaur park is not on the horizon.

That hasn’t necessarily stopped Horner, though, as the paleontologist has worked to create a small dinosaur using chicken DNA, which stems from a theory he explained in his book How to Build a Dinosaur.

While a reverse-engineered dinosaur is likely not to arrive before Jurassic World hits theaters on June 12, hear more about the Indominous Rex from the film’s director, Colin Trevorrow.
