Zoo in Warsaw installed a cage with a ‘caveman’ which helps visitors learn about the lifestyle of people from prehistoric times, the authors of the project say.

Caged man and woman, dressed in animal skin, spend time picking fleas, keeping fire in the fireplace and observing people who walk in front of their dwellings.

The role of prehistoric people is played by two volunteers: one eighteen year old girl and twenty four year old man.

- Our cave people are very calm and polite. They do not bite, but they are worried about many unknown people who pass in front of their dwellings - said Ewa Zbornikowska, deputy director of the zoo in Warsaw.

- This is an interesting way to encourage visitors to reflect on the man's place in the universe - she said.

Exhibition, which will last until Sunday, is followed by series of presentations on the life of Flintstones family, their customs and their place in the contemporary culture.
