“…Homo sapiens doesn’t seem able to cut himself off at the supply end. He’s one of the few species that doesn’t limit reproduction in the face of dwindling resources. In other words - and up to a point, of course - the less we eat, the more we fuck.’‘How do you account for that?’ said Jimmy.‘Imagination,’ said Crake, ‘Men can imagine their own deaths, they can see them coming, and the mere thought of impending death acts like an aphrodisiac. A dog or a rabbit doesn’t behave like that. Take birds - in a lean season they cut down on the eggs, or they don’t mate at all. They put their energy into staying alive themselves until times get better. But human beings hope they can stick their souls into someone else, some new version of themselves, and live on forever.’‘As a species we’re doomed by hope then?’ ‘You could call it hope. That, or desperation.’ ‘But we’re doomed without hope, as well,’ said Jimmy.‘Only as individuals,’ said Crake cheerfully.‘Well, it sucks.’‘Jimmy, grow up.’Crake wasn’t the first person who ever said that to Jimmy.”

“Jimmy, look at it realistically. You can't couple a minimum access to food with an expanding population indefinitely. Homo sapiens doesn't seem to be able to cut himself off at the supply end. He's one of the few species that doesn't limit reproduction in the face of dwindling resources. In other words - and up to a point, of course - the less we eat, the more we fuck.""How to do you account for that?" said Jimmy"Imagination," said Crake. "Men can imagine their own deaths...human beings hope they can stick their souls into someone else...and live on forever.”

“The male frog, in mating season," said Crake, "makes as much noise as it can. The females are attracted to the male frog with the biggest, deepest voice because it suggests a more powerful frog, one with superior genes. Small male frogs - it's been documented - discover that if they position themselves in empty drainpipes, the pipe acts as a voice amplifier, and the small frog appears much larger than it really is.""So?""So that's what art is, for the artist," said Crake. "An empty drainpipe. An amplifier. A stab at getting laid.""Your analogy falls down when it comes to female artists," said Jimmy. "They're not in it to get laid. They'd gain no biological advantage from amplifying themselves, since potential mates would be deterred rather than attracted by this sort of amplification. Men aren't frogs, they don't want women who are ten times bigger than them.""Female artists are biologically confused," said Crake.”

“Jimmy found himself wishing to make a dent in Crake, get a reaction; it was one of his weaknesses, to care what other people thought of him.”
