In Margaret Atwood's dystopian novel MaddAddam, the genetically engineered humanoid species is called the Crakers.
The Crakers were created by the scientist Crake as part of an attempt to redesign humanity after the destructive failures of modern civilization. They are engineered to have traits intended to reduce aggression, hierarchy, disease, and environmental damage. Their biology and behavior are central to Atwood's speculative vision of a post-pandemic world.
MaddAddam is the third novel in Atwood's speculative trilogy, following Oryx and Crake and The Year of the Flood. The Crakers appear across the trilogy, so readers may encounter them before reaching the final volume.
They should not be confused with pigoons, genetically modified pigs designed for organs, or wolvogs, engineered creatures resembling wolves. MaddAddam was published in 2013 and combines ecological catastrophe, biotechnology, religion, and survival.
