In one of the early scenes in Jurassic Park , the 2 scientists nervously ask John, the park’s creator, how he could prevent the velociraptors from reproducing. Easy, he says, all the dinosaurs are female.
Despite his reassurances, the orientation video for visitors at the park reveals the fatal flaw in his plan – frog DNA. Later, when Jeff Goldblum discovers hatched dinosaur eggs, he remembers that some frogs, in the absence of males, spontaneously change gender in order to perpetuate the species. He deduces that the same thing must have happened here, enabling baby dinosaurs (and crappy sequels). Life finds a way.
In few places on earth is that more evident than at today’s destination – Mt. St. Helens . Just over 30 years ago, all life within a 17.5 mile radius of the volcano was annihilated and scientists feared it would take hundreds of years for the ecosystem present before the blast to rebuild itself. Today, only 31 years later, the state of life around the volcano has surprised nearly everyone.
