Visitors to Warsaw's zoo are being greeted by two "Homo sapiens" peering out from a cage – humans in animal skins trying to spark interest in man's caveman ancestors.
Organiser Maria Mastalerz says the weeklong "performance" aims to attract interest in a play, "Caveman," showing in the Polish capital. But she says it also carries a message that humans today are not all that different from their prehistoric ancestors.
Dressed in furs and animal skins, the young woman and man smoked a fish over a fire Friday, poking it with a stick, or stared from behind bars at startled zoo visitors.
The display runs through Sunday.
