|"Evolution happens gradually as the eco-system changes. This doesn't just happen overnight."|
|— Astrid "The Genius" Ellison in Gone|
During Sam, Astrid, Quinn, and Edilio searched for Little Pete in the beginning of Gone, Astrid discovers a dead seagull on the pavement. After further observation she notes that the seagull has undergone some type of mutation, as it appeared to have grown talons, a trait commonly found in birds of prey. Seagulls are the first animals in the novels that appear to have mutated in the FAYZ .
