In order to study the many facets of primate behaviour, scientists have populated a small island near Puerto Rico with a thousand rhesus monkeys. Access to the island—dubbed ‘Monkey Island’—is granted only for research purposes, creating a vast and unusual outdoor lab.
As the researcher interviewed for the National Geographic video on the island says, because the monkeys are wild and are free to populate the island, “the concept here is different: we are in cages, and the monkeys are free.”
