Abrading tool known to be the oldest one goes back 350,000 years

In the year 1960s, a round stone was excavated at the very famous Israel Tabun Cave tends to stand as a representation of the being the oldest known rubbing or grinding tool, and the researcher say that this tool was used a good 350,000 years back. A technological turn is marked on the specimen concerning the manipulation of the objects that have wide, flat as well as stone surfaces; this is said by the famous archeologist named Ron Shimelmitz. He is an archeologist who is in Israel at the University of Haifa along with his colleagues. In those times, the respective stones implemented such features of having sharp and pointed edges. The reason behind the microscopic polish as well as microscopic wear which developed on the worn section of the stone excavated in Tabun was because of the stone under-going processes such as rubbing as well as grinding, against the material which was relatively soft, examples of which include the hides od animals and plants. This report was concluded by the scientists in the month of January in the famous Journal of Human Evolution.

Around a good 200000 years ago, there were stones which are said to be very similar to this one and bear prominent signs of the same kind of abrasion. Although till date, it still remains as a mystery for people as to how and for what reason was the Tabun stone used in the old times and people are very curious about it. Almost around a good 50000 years back, the groups of humans were making use of grinding stones for the preparation of plants as well as other kinds of foods, this information has also been revealed by Shimelmitz. The process which was done by the team was that they made a comparison between the microscopic elements which were found on the famous Tabun stone with the ones that were produced during experiments by making use of nine similar types of stones which were also collected quite near the cave.
