One of the pillars of human technology is the creation of stone tools. However, a new study reveals that human beings are not the only creatures on Earth that could yield this tool. Archeologists in Brazil reveals that bearded capuchin monkeys make these tools too.
For the first time outside Asia and Africa, archaeologists have discovered that the capuchin monkeys in Brazil have used stone tools, such as hammers and anvils, for 700 years.
A new experiment revealed that capuchin monkeys will punish other monkeys who have been given more food. Yale researchers say this is the first evidence suggesting that the psychology of spite extends deeper into our evolutionary history than previously thought.
Researchers have discovered that humans and monkeys perceive – and misperceive – the world in similar ways.
Primates using tools isn't exactly a new trick. Researchers have long observed apes using sticks to dip for ants, monkeys using mirrors to investigate their own bodies, and even chimpanzees using 'spears' when hunting. Now, however, researcher have found the first evidence that not only do monkeys crack nuts with rocks, but they use various and changing techniques to do it.
