"Changes can occur very quickly. Human beings are transforming the planet, and nobody knows whether it's a dangerous development or not. So these behavioral processes can happen faster than we usually think evolution occurs. In ten thousand years human beings have gone from hunting to farming to cities to cyberspace. Behavior is screaming forward, and it might be nonadaptive. Nobody knows. Although personally, I think cyberspace means the end of our species." "Yes? Why is that?" "Because it means the end of innovation," Malcolm said. "This idea that the whole world is wired together is mass death. Every biologist knows that small groups in isolation evolve fastest. You put a thousand birds on an ocean island and they'll evolve very fast. You put ten thousand on a big continent, and their evolution slows down. Now, for our own species, evolution occurs mostly through our behavior. We innovate new behavior to adapt. And everybody on earth knows that innovation only occurs in small groups."
