Primates are just like us - intelligent, quarrelsome, family-centred. Huge armies of Hamadryas baboons, 400 strong, battle on the plains of Ethiopia to steal females and settle old scores. Japanese macaques beat the cold by lounging in thermal springs - but only if they come from the right family. An orang-utan baby fails in its struggle to make an umbrella out of leaves to keep off the rain and young capuchins can't quite get the hang of smashing nuts with a large rock, while chimpanzees, our closest relatives, have created an entire tool kit to get their food.
