People in prehistoric times collected the tools of their ancestors

How were memories exchanged in prehistoric times? A study reveals that ancient Eastern humans reused ancient cut stones in a tool set they made to preserve the memory of their ancestors.

Flint napping plays an important role in Mesolithic society, in prehistoric times. It was during this time that she benefited from the advent of new technology using a soft striker. In this video from Intrap (National Institute for Preventive Archaeological Research) find out how the first humans designed their instruments.

The Patina Produces a chemical reaction that occurs specifically Tools used by prehistoric humans. This patina is formed over time under the influence of certain chemical and environmental conditions, and affects various materials such as metal, glass and various types of rocks. If the history of an instrument is not reconstructed, thanks to the fact that it is at least imaginable, the cut stones display this patina.

Paleolithic humans “recycled” stone tools made of patina, especially in the Near East.

The differences between freshly cut stones and old ones lie in their color and roughness. Previous archeological studies have already highlighted this fact Cut stone tools Men “recycled” with a patina PaleolithicEspecially in the Middle East.

Preserves the memory of older devices

A The study was recently published in the journal Scientific reports Patented material on the site of Revadim in Israel has been analyzed sinceUpper Achilles Especially between 500,000 and 300,000 years ago. Identified tools were used especially for scraping and cutting surfaces, which were found in contact with the remains of elephants with straight horns on both sides. The authors explain that the tools found on this site have two life cycles, separated by a long interval. The first wheel is about the design of the cut stone and the immediate use of the tool by the designers. The second was later left unused, which allowed one to own a pat.

The second cycle began when someone found the patina object, exposed the stone beneath the patina, and shaped and sharpened it. The authors are unable to explain whether these patinated stones were harvested by humans from their ancestral land or brought to the Revadim site by people from another region. However, selection and collection go hand in hand Recycling These stones were intentional. Such a recycling purpose may be motivated by financial reasons. The stone already has the shape of an instrument, which was functional, and may again be so. However, the authors suggest that the reuse of patina stones was inspired by other factors.

The authors point out that the shape of most of the recycled equipment has not changed significantly. The edges were sharpened, but most objects were used to scrape and scrape surfaces during their second life cycle, and some during their first life cycle, perhaps corpses, intended for cutting.

The authors interpret this as the will of the people who collected the patented objects, to preserve these objects as much as possible and to give them full functionality. This combination of ancient devices in the recent population may have been inspired by the technological power they would have acquired in their first life cycle. The collection and preservation of these ancient devices would have made it possible to create and maintain a connection of memory between them. Ancient human population And recently. The protection of these devices would make it possible to protect the root of an object through the way it works and the memory of the people who used it.
