The Crakers are the result of Crake’s project “Paradice.” He pitches them as “floor models”—or examples of all of the various genetic modifications that could be sold separately to parents who were willing to pay for more genetically perfect children. But it eventually becomes clear that the Crakers are Crake’s solution to what he sees as human imperfection, and that his plan had been to eradicate humanity as we know it and leave the Crakers in its place. They are strikingly beautiful, with perfect features and flawless skin that is immune to UV damage. They have a digestive system similar to that of a rabbit, so they can survive on a wide variety of simple vegetation, so food is not scarce. Romantic love has been bred out of them entirely: sex occurs as a purely reproductive act, once every three years per female. When a female Crake is ovulating, she gives off a pheromone scent and her backside turns blue (this trait is borrowed from baboons). Then males know they can pursue her sexually, but if a male is not chosen he does not feel any disappointment or anger. The rest of the time, the Crakes are basically sexless, and sexual or romantic frustration is completely absent in them. Crake also tried to breed religion, history, and art out of the Crakers, but it appears he has been unsuccessful. The Crakers ask many questions about where they came from, and with Snowman’s guidance they build a kind of mythology for themselves, where Crake is (ironically, because he would hate any kind of mythology) their god. They also begin, towards the end of the novel, to make art—they build a likeness of Snowman in the hopes that it will help him to return safely from his trip. It is unclear whether or not we should consider the Crakers “human,” but their interest in art and history is distinctly humanistic, and suggests they are more like us than they may seem at first.
