Macaques on a remote island are cracking the code of tool use
In short: Scientists discovered a population of long-tailed macaques using stone tools to open shellfish. This behavior challenges our understanding of animal intelligence and reveals how species adapt—and sometimes over-exploit—their environments.
On Piak Nam Yai Island in the Andaman Sea, researchers observed long-tailed macaques (Macaca fascicularis) employing sophisticated hammering techniques with stones to crack open molluscs. While tool use is traditionally associated with great apes like chimpanzees, these monkeys have developed their own distinct methods for harvesting coastal resources.
The study by primatologist Amanda Tan highlights a significant ecological concern: the monkeys may be harvesting shellfish so efficiently that they are exhausting their own food supply. Such a unique example of non-human species depleting resources illustrates how advanced cognition can influence ecological stability.
