In the rainforests of Borneo and Sumatra lives a creature local Dayak people call the "Orangutan" or "Old Man of the Forest". Orangutans are indeed one of our closest living relatives. We visit the exceptional Ganung Palung Reserve in Borneo, where we follow individual orangutans at key stages in their life to look at the trials they face and the kind of decisions they make in this taxing environment. The whole tapestry of orangutan life may be far richer than was previously thought. Like us, orangutans grow and reproduce slowly. We observe the infant and young orangutans and also observe their social structure and survival tactics.
