Not only humans, many monkeys have entered the Stone Age from 3000 years ago

Is that the ability they think of themselves, or do they look at humans and imitate them?

To be as successful as it is today, people have undergone an evolutionary process lasting millions of years, originating in the Stone Age from 3.6 million years ago.

But humans are not the only primate species to go through this period. In July 2016, scientists confirmed that capuchin monkey species know how to use stone to make tools. In 2018, another species, the white-faced cape monkey in Panama, showed similar behavior.

Most recently is the case of bearded capuchin monkey in Serra da Capivara (Brazil) national park. Science has previously observed how this monkey uses stone as a tool to separate seeds , dig up soil, process fruits and seeds, even to express the desire to " do it". However, they recently confirmed that they have done so since . 3000 years ago - the period when Egyptian civilization was still prospering.

Monkeys use stones as a tool to separate seeds.

The question is whether this monkey learns to use stones from humans. If so, it is very likely that capuchin capuchins have defeated humans and chimpanzees in terms of their ability to discover stone use.

To get the answer, the research team of Dr. Tomos Proffitt from University College London tried to discover where the monkeys often took stone bricks to crush cashew shells. They found nearly 1700 stones that were likely used by them, scattered throughout the area. Some are buried underground. In it, 122 is confirmed by the traces of monkeys on the surface.

The chronology of these stones is also different. In it, the deepest and oldest pill is 3000 years ago - that is, more than 450 monkey generations have passed.

However, there is a historical gap between the dates of the stones, which fell to 640 - 565 years ago. Experts are not sure if this is because the monkeys stopped using stones, or because they left the area.

According to Dr. Michael Haslam, people have also appeared in this area for thousands of years, bringing with them advanced tools. But it is also difficult to conclude that this monkey learns of humans, because history recognizes that humans recognize the taste of cashew nuts because of the monkey's eating them.
