Blombos Cave in South Africa may have shield a group of early humans whose tool - take a shit techniques outpaced those of other groups by many thousands of years . Today scientist announced the discovery of more advanced tools from this unusually innovative civilization .
Previously , research worker have found grounds that people who lived in Blombos Cave 75,000 twelvemonth ago produced jewelry and shell beads that only became common among other groups of human beings roughly 30,000 to 20,000 year ago . And now a inquiry squad led by Vincent Mourre has more grounds that the the great unwashed of Blombos were the in high spirits - tech civilization of the former human humankind . Apparently these mass invented a tool - make proficiency call “ atmospheric pressure flaking , ” a means of creating very knifelike tongue , about 55,000 years before humans elsewhere in the world did it .
grant to a liberation about the enquiry , published today in Science :
The tool - making technique , called pressure flaking , involves using an animal bone or some other object to exercise pressure near the boundary of a stone piece and carve out a relatively small chip . A tool - maker would typically first strike a stone with hammer - like tools to give the piece its initial figure ; then they would apply pressure - flaking to refine the blade ’s edge and shape its bakshish . The technique has been see a fairly late innovation , arising about 20,000 class ago .
It ’s unknown how these people came upon such a modern proficiency so many thousand of years before others did . It ’s potential , however , that their ideas about jewellery and putz - making gave the an advantage when they and their progeny transmigrate out of Africa 60,000 years ago . Their ideas may have spread to peoples in Asia and Europe , and mathematical group with this technology may have come to dominate other parts of the world because of their superior abilities to hunt and give themselves .
It ’s very possible that the multitude of Blombos Cave were the very first technical innovators , and that we have them to thank for all the machines and sophisticated tools we take for granted today .
