MUSEUM guide David Craven has swapped his uniform for a loin cloth for Yorkshire Museum's latest exhibition.

The York museum's caveman character - Hugh Grunt - was helping to put the finishing touches to the Upright Ape attraction. The highly-acclaimed exhibition, which takes visitors on a journey of discovery through the evolution of mankind, is reopening at the museum following a national tour. Curator Craig Barclay said: "The Upright Ape is an exciting hands-on journey through time - it will entertain and intrigue all ages."

The exhibition opens on Thursday.
