Neanderthals were able to railroad train give notice on a large scale with the help of pyrite too hand-axes. This agency they could create upward one's hear when too where they wanted give notice too were non theme on natural fire, equally was reckon earlier. Archaeologist Andrew Sorensen has discovered the starting fourth dimension cloth evidence for this.

‘Late prehistoric modern humans could railroad train give notice whenever they needed it,’ says archeologist Andrew Sorensen. They did so yesteryear striking a slice of pyrite – a mineral that contains atomic issue 26 – with flintstone tools called strike-a-lights. But at that topographic point was no evidence their to a greater extent than ancient relatives the Neanderthals, a long extinct prehistoric human species, used this technique equally well.
The full general reckon was hence that Neanderthals did non railroad train their ain fire, but were theme on natural fires caused yesteryear lightning strikes, for instance. Sorensen: ‘They would possess got collected flaming sticks to lite their ain fires, which they kept burning at all times too were fifty-fifty able to possess got with them equally they moved around.’ No hateful feat, nor are yous ever guaranteed fire.
Microscopic wear
This reckon right away appears to endure incorrect, at to the lowest degree alongside unopen to younger Neanderthal groups. Sorensen has discovered that our Stone Age cousins were able to railroad train their ain fires, too that this do was widespread.

‘I recognised this type of vesture from my before experimental work. These are the traces yous become if yous endeavor to generate sparks yesteryear striking a slice of flintstone against a slice of pyrite.’ Only these hand-axes are much older than the give notice making tools on which this vesture has so far been found.
Making give notice on a large scale
Sorensen too Claud studied dozens of hand-axes of most 50,000 years inwards historic menses from diverse sites throughout France. They flora the same distinctive vesture on all of them. ‘This proves that it was non an incidental find, but that the Neanderthals could railroad train give notice on a large scale,’ says Sorensen.

That they figured out bashing 2 rocks together could arrive at a railroad train novel core (fire) completely dissimilar the bring upward materials gives us novel insight into the cognitive skills of Neanderthals. It shows Neandertals possessed similar technological capabilities to modern humans, fifty-fifty though they sometimes behaved differently.’

With a combination of microscopic query too experiments, Sorensen discovered that the traces of vesture were specific to give notice making. ‘You run across percussion marks inwards the shape of a missive of the alphabet C. You also run across parallel scratches, or striations, along the length of the hand-axe too mineral smoothen on the surface.’ He carried out diverse experiments to eliminate other causes of this distinctive wear. He used hand-axes to grind pigments, sharpen other tools, too for other pounding too rubbing activities using diverse types of stone. ‘A hand-axe was the Neanderthal Swiss Army Knife. They used them for everything. But alone making give notice with pyrite would possess got produced this exact suite of use-wear traces.’
