Human Animal Displayed by Zoo

COPENHAGEN -- In one cage, a baboon swings from vine to vine.

In another, a lion roars.

In a third, a human being types away at a computer.

The Copenhagen Zoo has placed two tame humans in a plexiglass cage beside the baboon exhibit -- as part of an experiment to make visitors think about their ties to nature.

The Danish homo sapiens couple, Henrik Lehmann and Malene Botoft, moved into their new, see-through home last Sunday.

"It's all about trying to behave, to act naturally with people staring at us," said Lehmann, a 35-year-old acrobat who came up with the idea.

"We get the weirdest feeling when people look at how we live; what books we read; what we cook; what records we play," Lehmann said through the plexiglass on Thursday. "It can be really hard to be on show on all day."

Like the zoo's 250 other species, the human couple has a sign outside its 30-square meter habitat: one describing homo sapiens, including main characteristics, life expectancy, average number of young, and distribution on earth.

The human cage also has a kitchen and bedroom where the couple sleeps.

But some of their activities they keep private: showering and visiting the bathroom.

Lehmann said they are more tired of giving interviews than of being watched by fellow human beings.

"We don't notice visitors any longer. If I want to pick my nose or my toes now I do it," he said.

Lehmann's pregnant girlfriend, Botoft, is not new to displaying how she lives.

At last year's United Nations Social Summit in Copenhagen, she and her brother, Rasmus, lived for a week in the same makeshift plexiglass house to show thousands of delegates how typical Danes live.
