In the spring and early summer of 1998, the City of Edinburgh Museums and Galleries brought a landmark exhibition to the capital's City Art Centre as part of the International Science Festival's tenth anniversary.

In the course of the last few years, the Danish-based United Exhibits Group has perfected and applied the latest exhibition technology to the oldest question of all, by literally breathing life into the debate around human evolution. The result is Missing Links - Alive! - an exhibition tracing the human journey from the Rift Valleys of Africa to the stars.

The core of the exhibition is a series of dramatic, life-sized, animated tableaux, or dioramas, each depicting a key stage in the human story.
