In Oryx and Crake the lead scientist Crake has made his own people from scratch, called The Crakers, which he sees as an improved human species. Crake sees the human being as a ‘faulty’ model and so creates the Crakers as his version of the perfect human to survive in place of Homo sapiens. He and his team of scientists have decided what the Crakers should look like, what kind of biological features they should have and how they should act.
The Crakers are a genetically engineered species designed by Crake to take the humans place in the world after Crake destroyed human kind with a special disease called Blyssplus Pill. Besides, Crake created them as humans but removed everything he disliked as his goal was to make a species which wouldn’t destroy our earth or destroy themselves, something he thinks the humans do. In addition to these basic factors, Crake redesigned the human mating ritual by removing monogamy to go into heat at a certain time and that the males would court the women in hope that she would choose him to reproduce with. To eliminate any emotional attachment, a female’s genitalia turned a dark shade of blue once every three years which attracted the males of the community, whose penises acclimated to the same color to show their interest in mating.
