Dr. Malcolm warns that the park is doomed by "chaos theory" — a complex system like Jurassic Park cannot be perfectly controlled, and tiny errors will cascade into disaster.
During a tour, a powerful storm hits, and a disgruntled park employee (Dennis Nedry) shuts down the security system to steal dinosaur embryos for a rival company. With the fences off, the dinosaurs escape. Jurassic Park by Michael Crichton EPUB
Using their knowledge of dinosaur behavior and park systems, Grant and the children manage to contact the mainland and get the park's power back online. They reach the visitor center to escape via helicopter. With the fences off, the dinosaurs escape
The group soon discovers the fatal flaw: the dinosaurs have been breeding. The assumption that they are all female was wrong, as some frogs (used to fill DNA gaps) can change sex in a single-sex environment. The lysine contingency is also flawed; dinosaurs get lysine from eating other animals. The group soon discovers the fatal flaw: the
The dinosaurs are recreated from DNA extracted from prehistoric mosquitoes preserved in amber. To control the population, Hammond's scientists engineer all dinosaurs to be female and require the amino acid lysine from their food, making them theoretically dependent on humans.
In the end, Hammond's dream is destroyed. The park is abandoned, and the dinosaurs are left to die or be killed (via a contingency plan to poison their food). The survivors learn that life cannot be contained or controlled — it "finds a way."
