In this episode, a new BBC series exploring primates. The world of monkeys is much larger than you might think. So many species populate the planet, and it's surprising to see how each has developed different abilities, based on the needs of its environment. We'll begin this wonderful journey in Brazil, to see the bearded capuchin, then move to the coast of West Africa, home to the drill monkey, and on to India, where we'll encounter the cunning macaques, before continuing on to Nepal and the Congo.
