Animal behavior researchers captured Capuchin monkeys using stone tools in Brazil's Ubajara National Park to dig out food like spiders. Monkeys exhibited 'hands-only', 'stone-digging', 'stick-probing', and 'stone-stick' methods based on weather and tool efficiency.
Studies on capuchins using tools reveal a 'Monkey Stone Age' unfolding, highlighting their intelligence akin to larger primates. Initial observations in mid-2000s led to ongoing research on their tool-use behavior, initially sparked by botanist Alicia Ibañez's findings in Panama.
The discovery of capuchin monkeys using tools emerged gradually, with researchers focusing on specific populations like those in islands of Panama. These findings highlight the intricate behaviors and intelligence of these pint-sized primates.
Recent studies on capuchin monkeys in Brazil and Panama showcased their ability to use stone tools for foraging, similar to larger primate relatives. Researchers note gradual emergence of understanding these behaviors since the mid-2000s.
