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.

It could be said that the advance of civilization has not so much moulded modern sexual behaviour, as that sexual behaviour has moulded the shape of civilization.

She only ovulates at one point during the cycle, so that mating at all other times can have no procreative function. The vast bulk of copulation in our species is obviously concerned, not with producing offspring, but with cementing the pair-bond by providing mutual rewards for the sexual partners. The repeated attainment of sexual consummation for a mated pair is clearly, then, not some kind of sophisticated, decadent outgrowth of modern civilization, but a deep-rooted, biologically based, and evolutionarily sound tendency of our species.
