Behavioral Economics: Chimpanzees Will Travel Farther for Preferred Foods

Just as humans will travel to their favorite restaurant, chimpanzees will travel a farther distance for preferred food sources in non-wild habitats, according to a new study from scientists at Chicago's Lincoln Park Zoo that publishes on March 17 in the journal PeerJ ...
