Because they are close relatives, great apes - particularly chimpanzees and bonobos - can help humans understand hominization, the evolutionary process that led to the appearance of man. Filmed in Nigeria, Tanzania and a Dutch zoo, this documentary explores the differences and similarities between apes and humans. Despite those who place man at the pinnacle of creation, all these species, from the same stock, have reproduced with each other several times over the course of history.
