“It's like the control insects at the Laboratory. Di d I ever tell you about them? Well, we keep a lot of insect colonies in big glass jars out there. Some of them have been breeding for twenty-five years. That's a thousand generations. All they know about life is what goes on inside their Jar. They haven't been exposed to pesticides or pollution, so they haven't developed immunities or evolved in any way. They stay the same, generation after generation. If we released them into the outside world, they'd die. I think something like that happens after seven generations in Savannah. Savannah gets to be the only place you can live. We're like bugs in a jar.”
