Archaeologists have proved that a thin cord was found in the Parking lot of Neanderthal in France, is manufactured by spinning — he twisted of the three wood fibers. This gave scientists reason to believe that Neanderthals, in addition, knew how to count to three, and to distinguish between right and left. Their paper published in the journal Scientific Reports.
Known until now the oldest surviving samples of the yarn 17-19 date back to thousands years ago and are associated with Homo sapiens (Groaned in Israel and the cave of Lascaux in France).
Described in the new work, the cord found on the Neanderthal Parking Abri-du-Mar in the valley of the ardèche river in the South-East of France. The context in which it is discovered dated by other finds by the method of electron paramagnetic resonance and uranium-thorium method from 41±2 thousand years ago to 52±2 thousand years ago. Fragments of the cords at this location was found before, but they were too small. This same finding has a length of 6.2 mm, which allowed examining it under a microscope to find out exactly how the cable was manufactured.
The researchers, led by anthropologist Bruce hardy (B. L. Hardy) from the American Kenyon College found that it is made of fibres obtained from the inner side of the bark of some tree, presumed to be the pine, but not the breed that is now found in the vicinity of Abri-du-Mar. The fibers were twisted into yarn clockwise and then three strands in the cord counter — clockwise.
Cord found adhering to otdau size of about 6 inches. Scientists are not sure if it turned out accidentally or cord and otshchep were part of a single instrument (for example, cord otshchep could be attached to the arm). It is also possible that the cord — the rest of the handbag-type shopping bags, which otshchep transferred.
As emphasized by hardy and his colleagues to produce such a cord, the Neanderthals had to have, among other things, some arithmetic skills and your spatial reasoning skills: to distinguish between three and two, twist clockwise and counterclockwise, i.e. right and left. According to them, this is another indication that Neanderthals in their cognitive abilities differed from anatomically modern humans is not as strong as commonly believed.
Previously, scientists found that Neanderthals knew how to paint, to tar, to handle the wooden weapon with fire and use flint.
