Budweiser’s Clydesdales, Coca-Cola’s polar bears and CareerBuilder.com’s chimpanzees have all achieved fame through Super Bowl commercials. If Chicago’s Lincoln Park Zoo were in charge of casting, however, the suit-and-tie-clad chimps would be in danger of losing their starring role. The zoo is campaigning to stop CareerBuilder from airing its scheduled commercial Sunday, claiming that the anthropomorphized portrayal of the endangered species will make viewers less concerned about wildlife conservation. The company has been featuring chimps in Super Bowl ads since 2005, but a new Duke University study has added fuel to the critics’ fire. The study’s leader, assistant professor of evolutionary anthropology Brian Hare, is especially worried that Africans will be misled and attempt to capture and sell the wild primates to Westerners as pets. We’ll go out on a limb and say that television viewers around the world are highly evolved enough to recognize the entertainment value of a commercial without going bananas, unlike the researchers.
