Unlike Dinosaurs and Prehistoric Beasts, Cavemen combines CGI with actors to portray the characters in the story of man. Initially this seems to make it far less technically impressive than the earlier programs--memories of Stanley Kubrick's 2001 are inevitable--but fortunately the acting is superb and the viewer soon forgets that these are people in monkey suits. The series also makes use of a special effect called "deep time-lapse", which shows in a matter of dramatic seconds the thousands of years of geological changes that sped up our ancestors' evolution. Wilson himself takes part in the action as if he is a modern-day naturalist following lions across the Serengeti rather than creatures long extinct. This approach makes for a more immediate as well as poignant interpretation of history: the result is an enlightening and moving tribute to the human journey. --Kristen Bowditch
