Chimpanzees develop cultures in the wild which distinguish them from other groups, scientists have found.
A community of Sonso chimpanzees living in Uganda’s Budongo Forest was filmed using crushed leaves and moss to collect water.
During six days of continuous observation, zoologists discovered that the group left their leaf-sponges at their watering hole and picked them up the following day – in the same way a human leaves a cup near a sink.
The Alpha Male ‘Nick’ was also seen to use moss to collect water, and the new technique was quickly adopted by many of the chimpanzees.
