The culture in primates and their learning ability

Primates have culture, a fact that has been accepted for years. An example is the groups of orangutans that inhabit the banks of the Kapuas River in Borneo (Indonesia). Although within each society they eat practically the same things, when comparing the riverbanks, the foods vary by 60%. These cultural habits can be transmitted from generation to generation. In Panin, Ivory Coast, archaeological evidence has been found that chimpanzees in that region used stones as nutcrackers 4,000 years ago, the same ones their descendants use today.
