A group of scientists on their expedition to the Panamanian island of Jicaron has found out that white-faced capuchin monkeys have been using stones to crack open shellfish and nuts, just like humans did, centuries ago.
Back in 2004, the scientists observed the capuchin monkeys cleverly using stones but only returned in March in 2017 to catch these little guys on camera.

According to their research, the skill they developed was ‘by chance’ and don’t know when and how the inhabitants of the island of 6 million years began practicing such tactics.
White-faced capuchin monkeys are a medium-sized monkey species native to the jungles of the northern regions of South America and Central America. They are also known as the white-throated capuchin and the white-headed capuchin and are thought to be one of the most intelligent monkey species in the world.
Humans and capuchin monkeys go way back, they are best known as a companion for the ‘organ grinders’ and are also trained to assist individuals who are paraplegic.
No other local population of the island has proved to use such tactics in their daily lives. This marks the capuchin monkeys the non-human primates and the fourth observed group that has used stones as tools.
Other animal species who have demonstrated the use of stones in their day-to-day jungle lives include macaques in Thailand, West African Chimpanzees, and other species of capuchin monkeys in South America.
