Chimps on the hunt
David Attenborough watches a chimpanzee troop in the rainforestas they begin to organise a hunt. Each male chimp plays a specific role - driver, blocker, chaser and ambusher. David follows the chimps as they catch and kill a colobus monkey. They scream with excitement at the kill and share it the spoils. David comments on how this teamwork throws light on human ancestry.
