David Attenborough's entertaining romp through the world of monkeys has a serious side: for when we look at monkeys we can see ourselves. From memory to morality, from 'crying wolf' to politics, monkeys are our basic blueprint. Pygmy marmosets 'farm' tree sap; bearded capuchins in Brazil develop a production line for extracting palm nuts; white-faced capuchins in Costa Rica tenderly nurse the victims of battle; and in the Ethiopian highlands a deposed gelada baboon has got the blues.

What makes us human may not be uniquely human after all! We share love, language, guilt, envy, generosity, secrets, lies, and a sophisticated society with our closest relatives the monkeys!

From tiny pygmy marmoset in South America to aggressive baboons of Africa and compassionate toque macaques in Sri Lanka, NATURE travels around the world to capture never-before-seen monkey behavior that challenges many ideas about what is purely human. Academy Award©-winner F. Murray Abraham narrates this fascinating program that immerses viewers in monkey culture to reveal how and what monkeys teach their young, and how they communicate with each other.

Who are the cleverest monkeys? How much of our human experience do they really share? Just how smart are monkeys? You will find the answers to these provocative questions only in NATURE!
