The zoo in Adelaide has put a group of humans on display to raise awareness about primate conservation. The humans will be locked in an unused orang-utan cage for a month, in pretty warm weather conditions with bananas for food. They will be monitored by a psychologist who hopes to use the findings to improve conditions for real apes in captivity. Audiences are encouraged to vote for their favourite “ape” via mobile phone text messages, in the style of reality television shows, and at the end of the month, a “super human” will be selected to represent the zoo.
