What sequence is observed when studying wild capuchin stone tool use traditions?
Answer
Selection, transportation to an anvil site, and forceful impact
Direct observation of contemporary white-faced capuchin groups confirms that their stone tool usage is a deliberate, multi-step process rather than a random action. Researchers document the entire sequence of this 'Stone Age' behavior: first, the accurate selection of an appropriate stone deemed suitable for use as a hammer. Second, the animal must transport this hammer, sometimes over a distance, to a designated location recognized as a stable anvil site. The final step involves applying the necessary force through repeated, accurate impacts onto the target food item resting on the anvil to successfully gain access to the meal.
