Archaeologists have discovered a magnanimous draw of dispose   cutting tools and animal bone in Ain Boucherit , Algeria , some date to 2.4 million age ago . Not only does this find contribute considerably to the collecting of prehistorical stone tools from this period , but it undermines some of the   current theories we have   on the stock of humans .

Up until lately , the oldest Harlan Fisk Stone tools found in North Africa were 1.8 million years old   – again ,   in Algeria . It ’s thought that the utilization of such putz step by step spread around the continent from culture in East Africa ( the " garden of Eden " ) , where they were originally develop .

This theory hinge on the Oldowan tools of Gona in Ethiopia , which are 2.6 million years erstwhile and the very oldest Harlan Fisk Stone tools we know of to date . These Oldowan stone artifacts ( and those come up afterwards ) display distinctive markings , or flakes , that give the tools a sharp boundary that can be used for cutting .

The tools found in Ain Boucherit stop exchangeable marking and were get alongside 19 animal bones that look to show indentation marks   – an ancient hominin endeavour at shambles . But , according to a study put out inScience , what make them   really remarkable is their age . If what the investigator say is right   – and some experts not involved in the study haveexpressed doubts – the oldest in the collection are   only 200,000 years younger than the   old Lucy Stone tools in the globe .

This would mean the utilization of   Oldowan - elan tools spread more than 4,800 kilometers   ( 3,000 miles ) in a period of just 200,000 years . And while that might   seem like an extraordinarily long time , it is nothing evolutionarily mouth .

To escort the putz , Mohamed Sahnouni , lead source and   an archeologist at Spain ’s National Research Center for Human Evolution , and his squad used three methods . These includemagnetostratigraphyandElectron Spin Resonance ( ESR ) geological dating . They also break down   the animal bones found alongside the putz , identifying mintage of now extinct elephants , mastodons , horses , and pigs as well as antelope , rhinoceros , hyenas ,   and crocodile .

The results of the psychoanalysis reveal the putz in the ingathering are between   1.9 and 2.4 million class old .

Sahnouni proposes two explanation . Either this proves there was a speedy dissemination of stone tools from East Africa to place   outside the areaorit shows that   early hominins developed the habit of Harlan Fiske Stone tool in multiple locations severally – a finish that is not entirely discrepant withprevious studiessuggesting hominidsmigrated   further and earlierthan conventional theories put onward .

But there is something else to believe . In 2010 , at a land site in Dikika , Ethiopia , a squad of archeologist discovered3.4 - million - yr - old bonesthey say contain indentations created by stone pecker . Others have gainsay the call but if they are veracious , it pushes the timeline back once again . It would mean the original possibility – that East Africa was the hub of tool innovation   – holds genuine , it ’s just that it was taking lieu earlier than we thought .

In both casing , more enquiry is necessitate to substantiate these fresh claim .
