Of course Ian is awed by the fact that they actually made dinosaurs. It's hard not to be impressed. They are big and breathing and smelly and real. They're eating tree tops and shaking the ground as the walk and the paleontologists are ready to keel over from shock. Ian can appreciate this – it's brilliant. Wonderful. But he sees the business side of things and knows that dinosaurs aren't the only ones with scales – snakes are too.
The scientists are proud that they cracked the code. Thrilled that they can play God. Eager to please Hammond. Pleased that they can render the paleontologists speechless with facts and fall easily in love with the hatching eggs. They are confident in their numbers, the lysine contingency, the single sex environment. They are irritated with Ian's inability to trust their numbers.
Of course he doesn't trust their numbers. They're faulty. The world is not the same greenhouse it was millions of years ago. Just because you can make them doesn't mean it's a good idea. Just because you say they're all females out there doesn't mean they all are. Ian remembers his high school biology class and knows that the human species has continually evolved to meet the demands of its environment. Things constantly change – it's the only thing that stays the same.
As he sits in the car waiting for them to come back from looking for Grant and the kids, Ian laughs at the scientists who loved their computer schemes and electricity. He told them, he told them that you can't hold back life. It doesn't work. And now half of them are dead, the power is loose and fences down. The dinosaurs are probably breeding like crazy and what little remains of the humans are scrambling to get back to home base. This is life, he thinks as the game warden and Ellie run back to the car, move or be eaten.
