So much so that the characteristics of humans and chimpanzees were thought to be 'special', it was now seen in the wild macaw species of monkeys. Today, researchers said Wednesday that they saw the learning of using the various instruments or methods of the wild macaw monkeys. Using small tools, they can break nut shells or smell the soft part of the oyster.
Researchers from the UK and Thailand researched the long tailed Macac. These monkeys eat nuts, palm leaves and special types of marine mussels. Researchers observe how monkeys use two different functions of stone. They see, Maccross monkeys use hammers to break the two kilograms or more weights of nuts. On the other hand, they use sharp stones like knives and they use them to eat mussels.
The Royal Society published in the Open Science magazine, this article on research.
Prior to the study of Thailand's Piak Nam Yai Island, only wild chimpanzees used to be used in stone.
