Did you know that chimpanzees and humans have 98 percent of their DNA in common? You will after watching this absorbing 75-minute (including extras) documentary, featuring and partially narrated by renowned researcher Jane Goodall, who's been on the chimps' case for more than four decades. We see these African apes on the ground and in trees, playing, grooming, teaching, even killing one another. The scenes of them "fishing" for termites and ants using a stick for a pole make for extraordinary viewing; indeed, the film's principal message is that they and we are very much alike. And while the small screen can't capture the full majesty of what began as an IMAX film, one can sense the almost palpable three-dimensionality of the original. The DVD is also loaded with bonus features, including a 15-minute behind-the-scenes look at the filmmaking process and more. This is great stuff. --Sam Graham
