 At the visitor center, the group learns that the cloning was accomplished by extracting dinosaur DNA from mosquitoes that had been preserved in amber. DNA from frogs was used to fill in gaps in the dinosaur genomes. To prevent breeding, all the dinosaurs were made female. Malcolm scoffs at the idea of such controlled breeding, declaring it impossible. The crew witness the birth of a baby raptor and visit the raptor enclosure. Grant, Sattler, and Malcolm have reservations about the idea of resurrecting dinosaurs, but Hammond and Gennaro dismiss their fears.
