Jurassic World 3 Explains John Hammond's Mosquito Luck

Jurassic World: Dominion's opening scene is an ingenious retcon that explains John Hammond's amazing luck and Jurassic Park's dinosaur creation myth.

Warning: SPOILERS for Jurassic World: Dominion.

Jurassic World: Dominion's opening sequence explains how John Hammond (Richard Attenborough) was so lucky to find a fly preserved in amber that contained the DNA he needed to clone dinosaurs in Jurassic Park. Although director Colin Trevorrow's conclusion to his Jurassic World trilogy doesn't hit movie theaters until June 2022, fans can get a preview of Jurassic World: Dominion footage attached to IMAX screenings of Fast & Furious 9.

The pseudo-science Hammond and his genetics company, InGen, used to breed cloned dinosaurs in Steven Spielberg's blockbuster 1993 film was derived from the Jurassic Park novel by Michael Crichton. Hammond and his chief geneticist, Dr. Henry Wu (B.D. Wong) achieved this miracle of science by extracting dinosaur DNA from the blood sucked by flies in the Cretaceous era. The insects were found preserved in amber with the dino DNA in their blood intact. InGen's geneticists were then able to clone dinosaurs from the blood and the used amphibian DNA to fill the holes in the dinos' genetic code. Hammond's company cloned 15 dinosaur species in the original Jurassic Park. By 2015, when the theme park was rebuilt and successfully operated as Jurassic World, Dr. Wu was able to add hybrid monster dinosaurs like the Indominus Rex to InGen's menagerie.

Jurassic World: Dominion's opening scene shows the mosquito sucking the blood of a Brachiosaurus. Then, a battle between a Tyrannosaurus Rex and an even bigger apex predator the film introduces, the Gigantosaurus, commences, with the mighty T-Rex being killed by the Gigantosaurus. The fly then sucks the blood of the T-Rex from its corpse before it finds itself consumed by the amber, which preserves it and the dino blood it's carrying perfectly for the next 65-million years. Because John Hammond "spared no expense", InGen eventually finds this fly and extracts the DNA within it to clone Jurassic Park's original dinosaurs. Thus, in an ingenious retcon, the T-Rex in Jurassic Park is the clone of the T-Rex that died at the start of Jurassic World: Dominion, in a profound circle of life moment.

Colin Trevorrow decided to open Jurassic World: Dominion in the Cretaceous era to show the dinosaurs in their natural time and environment, which is something fans have seen yet in the five previous films. Not only did this move allow Trevorrow to integrate 7 new dinosaur species that also haven't appeared in the Jurassic movies before, including the Gigantosaurus, but it gave the director the chance to answer a question that the entire franchise hinges on: How did John Hammond get so lucky to find a mosquito that was able to suck the blood he needed to clone his dinosaurs 65 million years later? Jurassic World: Dominion's prologue ingenuously answers that question with a violent Cretaceous conflict and the fateful, blood-sucking insect that would provide the means for dinosaurs to live again in the 20th and 21st centuries.

Jurassic Park briefly touched upon the dinosaur cloning origin with the entertaining animated short film Hammond showed Dr. Alan Grant (Sam Neill), Dr. Ellie Sattler (Laura Dern), and Dr. Ian Malcolm (Jeff Goldblum), all of whom reprise their roles in Jurassic World: Dominion. Amusingly, Hammond's cartoon shows a fly sucking the blood from a Brachiosaurus' leg before it's trapped in amber. Jurassic World: Dominion's prologue embellishes the creation myth and links the fan-favorite T-Rex's death and resurrection via cloning to the origin story. This brings the Jurassic franchise full circle and cleverly explains John Hammond's one-in-a-million stroke of luck that enabled him to clone his dinosaurs.
