Here's evidence that humans are the only animals intelligent enough to desire demotion to an evolutionary chain...
Caged and barely clothed, eight men and women monkeyed around for thecrowds Friday in an exhibit labeled "Humans" at the London Zoo.
Visitors stopped to point and laugh, and several children could be heard asking, "Why are there people in there?"
London Zoo spokeswoman Polly Wills says that's exactly the question the zoo wants to answer.
"Seeing people in a different environment, among other animals ... teaches members of the public that the human is just another primate," Wills said.
"A lot of people think humans are above other animals," he told The Associated Press. "When they see humans as animals, here, it kind of reminds us that we're not that special."
