"Of all the non-specialists, the monkeys and apes are perhaps the most opportunist. As a group, they have specialized in non-specialization. And among the monkeys and apes, the naked ape is the most supreme opportunist of them all. This is just another facet of his neotenous evolution. All young monkeys are inquisitive, but the intensity of their curiosity tends to fade as they become adult. With us, the infantile inquisitiveness is strengthened and stretched out into our mature years. We never stop investigating. We are never satisfied that we know enough to get by. Every question we answer leads on to another question. This has become the greatest survival trick of our species."
