An international group of scientists from Brazil and the UK found that monkeys-Capuchins used the tools three thousand years ago. About it reported in a press release on Phys.org.

The researchers studied the behavior of monkeys in the Brazilian national Park Serra da Capivara. Scientists noticed that the Capuchins used stones from quartz to break up the cashews. They put the nuts on a large rock used as an anvil or solid tree root, and then hit it with a small piece of rock. After such attacks are characteristic traces on the stone tool, and the “anvil”, including brown spots from broken cashew fruit.

Experts then excavated the area in search of a similar fossil traces and found artifacts with notches aged up to three thousand years. The ancient stone was the tool, the less was its size. About 560 years ago, animals began to use tools larger, and 300 years ago, monkeys were switched to stones of such a size that they are now widely used.

It is known that instruments of labor are also chimpanzees (for more than four thousand years), and among other animals — birds, who break off branches in order to get their help insects out of tree bark.
