What is intelligence, exactly? Maybe that sounds like a simple question. We know—or think we know—what our own kind of intelligence is like. After all, we experience it on a daily basis.
But there are other kinds of intelligence. There is the intelligence of the hive—the complex behavior that arises from individually unintelligent organisms following a few simple behavioral rules in response to cues from the environment. And there is a kind of intelligence that inheres in the ecosystem as a whole. Evolution, over time, has created entities as diverse as crinoids and mushrooms and harbor seals and howler monkeys, all without a predetermined goal and without devoting even a moment of thought to the subject. You might even conclude that this kind of thoughtless intelligence is more powerful and patient than our own.
