In central Miami, birds have taken up residence in the empty apartment and office buildings. Chimpanzees that have escaped from Miami's zoos follow the birds into the apartment and office buildings to eat their eggs. The chimps realize that they need to let some of the eggs survive in order to increase the food supply. They also chase away predators that may harm the birds, like cats.

Chimps have spread all over the world. They have evolved into a Homo habilis- like creature. They have farmed the birds for their eggs and have discovored the art of breeding birds. Beacuse they still remember what humans did to them, they remain a primtive creature. They have evolved into Pan Homo. Pan Homo is a desendent of Chimpanzees that fills the niches of humans. It eats bird eggs, plants, and meat. It has a similar lifesyle to early human farmers.
