A prehistoric bone device “factory”
According to Peters and its fellow authors, bone tools were very few until about 500 500,000 years ago, making it difficult to identify a permanent approach to the formation and use of tools. It is now changing with the discovery of bone tool storage at the T69 complex of Oldovi Gorge, especially seven trenches excavated between 2015 and 2022. In addition to more than 10,000 stone tools, there were large fish, crocodiles and hippopotamuses, as well as elephants and grasses.
In all fossils and bone pieces, the authors identified 27 samples that were clearly bone tools, which is evidenced by deliberately removing, shape and edges of the bone edges to create a long shape. The authors have acknowledged that other non -intentional factors can cause such brightness, especially the rotation of the meat. But the meatic animal identified is less than 1 % of the time, and 27 samples do not show clear signs of such rotation.
It seems that bone tools were carefully chosen by the bones of the larger seeds, which usually selected elephants and hippopotamus. The authors wrote, “The exact physical knowledge and understanding of the shape of the bones is proposed, which is preferred to the bones of the thick organs and the repeated flicking method is used.” Large stone tools may have been replaced by these large bone tools, which may tell them why they became so rare after the appearance of a systematically manufactured lithing hand axis.
“From this discovery we are attracted to assuming that early humans significantly increased their technical powers, which was limited to the preparation of stone tools by then and now allows new raw materials to be included in the potential sample reservoir,” The co -author of the tower said Ignacio CSIC-Spanish National Research Council “At the same time, this expansion of technical abilities indicates the progress of the Hommes’ academic abilities and mental structures, who know that their stone functioning knowledge is to include technological innovations by molding bone manipulation.”
