The 65,000-year-old knife reveals a big secret

Tools found across Africa show that the ancestors of Homo sapiens also shared their knowledge. For the first time, researchers have come across objects that have exactly the same shape, so they may have been based on a template.

The study showed that the finds, also known as the “Swiss knife” of prehistoric history, were made in areas very far apart, according to a similar model. Knives were produced in huge quantities in South Africa about 60-65 thousand years ago – Writes The Guardian.

Knowledge is shared by individual groups of people

Since the tools also look the same, the researchers found that this is a sign that each community is connected to each other.

“What’s really exciting about this discovery is that it provides evidence of a long-term relationship between people before the Great Migration from Africa that affected all of our ancestors,” said Amy Way, the lead archaeologist on the research.

Researchers are really wondering why this large withdrawal, which occurred 60-70 thousand years ago, succeeded, while previous attempts failed.

“The main theory is that connections between people were stronger at this time,” Wai said. “This analysis shows for the first time that these were present in South Africa even before the Great Withdrawal.”

The Swiss Army Knife could be used in a number of ways: it was just as convenient for skinning as it was for cutting or drilling holes. Previous research has shown that in South Africa, these objects were also used as arrowheads, and in Australia as tip for spears, for shaping bones and skin, and for piercing and shaping wooden objects. In Africa, such objects were also found at a distance of 1200 km, which indicates that the relationship between each group was vivid, since the knowledge gained was transmitted to each other by neighboring groups. Wai says it’s also unique to use the same device in many parts of the world.

Sharing information could also be a key to the ancestor of modern humans, said Paloma de la Peña, a senior researcher at the McDonald’s Institute of Archeology at the University of Cambridge.

“The leading theory as to why modern humans replaced all other people outside Africa 60 to 70,000 years ago is that our ancestors

They were much better at building social networks,

Like other species, such as Neanderthals, who may have been more intelligent and stronger than individuals, but they weren’t very good at sharing information. Abundant discoveries show that these social connections were already in place at this time,” said de la Peña.
