“The reason I ask,” Malcolm said, “is that I’m told large predators such as lions and tigers are not born man-eaters. Isn’t that true? These animals must learn somewhere along the way that human beings are easy to kill. Only afterward do they become man-killers.” “Yes, I believe that’s true,” Grant said. “Well, these dinosaurs must be even more reluctant than lions and tigers. After all, they come from a time before human beings—or even large mammals—existed at all. God knows what they think when they see us. So I wonder: have they learned, somewhere along the line, that humans are easy to kill?”
