These Monkeys Are 3,000 Years Into Their Own ‘Stone Age’
For capuchin monkeys at Brazil’s Serra da Capivara National Park, tool use is a tradition going back millennia: A new study finds that these primates have used stone tools to process their food for the past 3,000 years, making it the oldest non-human site of its kind outside of Africa. But before early hominins intentionally flaked off pieces of stone to use as tools, it’s thought they used unmodified stone cobbles to process foods, much like the Serra da Capivara capuchins do today. After all, not all groups of capuchins use stone tools—so why do the ones at Serra da Capivara and at sites in Panama?
