The Lysine Controversy in Jurassic World: Fallen Kingdom

Introduction

The science in the Jurassic franchise has often been a subject of debate and scrutiny, particularly when it comes to the "lysine contingency." This genetic modification, designed to ensure that the dinosaurs, created in Jurassic Park, can survive only when fed with a lysine-rich diet, forms a crucial plot device in the original film. However, in the 2018 sequel, Jurassic World: Fallen Kingdom, the lysine contingency is brought back into question. In this analysis, we will explore the scientific and narrative basis of the "lysine contingency," and weigh whether dinosaurs, under proper conditions, should have succumbed to lysine deficiency at the end of the film.

The Lysine Contingency: A Scientific Overview

The "lysine contingency" is a method used to control the growth and survival of the dinosaurs created by genius geneticist Dr. Henry Wu. Lysine, an essential amino acid, is necessary for the proper development and survival of living organisms. Without lysine, the genetic code that ensures dinosaur traits will not function, causing them to die. This mechanism was initially presented as a means to prevent the dinosaurs from escaping and causing havoc when park maintenance was halted. However, this concept was called into question when it was discovered in The Lost World: Jurassic Park.

Scientific Explanations in The Lost World: Jurassic Park

In The Lost World: Jurassic Park, it is revealed that the lysine contingency does not hold throughout the entire timeline. The dinosaurs can still consume plant-based lysine, which they can obtain from the Cretaceous-period plants that still exist in the original park setting. Futhermore, the film introduces the concept of herbivorous dinosaurs consuming lysine-rich vegetation, which would then be assimilated by carnivorous dinosaurs. This development implies that the dinosaurs in the film are able to survive without the need for a continuous lysine supplement.

Implications for Jurassic World: Fallen Kingdom

When the mid-2010s see the resurgence of the dinosaurs, the restoration of the Isla Nublar park atmosphere, and the implementation of well-watered, lush flora, one might expect the "lysine contingency" to apply. Despite the return of the lysine contingency in Jurassic World: Fallen Kingdom, the dinosaurs are depicted to be thriving. This raises several questions: is the film's depiction scientifically plausible? And what does this imply about the scientific basis of the "lysine contingency"?

Survival Through Dietary Diversity

The survival of the dinosaurs in Jurassic World: Fallen Kingdom can be attributed to the natural cycle of the ecosystem. The film showcases a thriving ecosystem with a variety of plants that can serve as a lysine source. Lysine is naturally found in many plant species and has multiple sources in the Cretaceous ecosystem, including legumes and other nitrogen-rich plants. The dinosaurs, particularly the herbivores, would have had access to these resources, thereby maintaining their lysine levels without the need for continuous human intervention.

Narrative and Scientific Consistency

While the "lysine contingency" remains a pivotal plot device in the Jurassic series, its existence is often used more as a narrative tool than a strict scientific rule. The filmmakers use the lysine contingency to heighten tension and create a sense of urgency. The film's portrayal of the dinosaurs as adaptable and self-sustaining implies that the lysine-contingency is more of a temporary measure rather than an eternal constraint.

Conclusion

In summary, the scenario at the end of Jurassic World: Fallen Kingdom where the dinosaurs do not succumb to lysine deficiency is scientifically plausible under the conditions present in the film. The natural abundance of lysine-rich plants and the diverse dietary habits of the dinosaurs allow them to maintain their health and survival without the need for continual lysine supplementation. This conclusion is further supported by the narrative context of the film, which portrays the dinosaurs as hardy and resilient life forms capable of adapting to their environment.
