An international team of researchers, including scientists from Wits University, have substantially increased the age at which we can trace the emergence of modern culture, all thanks to the San people of Africa.
The research by the team, consisting of scientists from South Africa, France, Italy, Norway, the USA and Britain, will be published in two articles online in the prestigious journal, Proceedings of the National Academy of Sciences, today at 19:00 South African Standard Time.
The paper titled Early evidence of San material culture represented by organic artifacts from Border Cave, South Africa was authored by Francesco d'Errico, Lucinda Backwell, Paola Villa, Ilaria Degano, Jeannette Lucejko, Marion Bamford, Thomas Higham, Maria Perla Colombini, and Peter Beaumont.
Doctor Backwell is a senior researcher in palaeoanthropology, and Professor Bamford a palaeobotanist at the Bernard Price Institute for Paleontological Research at Wits University.
"The dating and analysis of archaeological material discovered at Border Cave in South Africa, has allowed us to demonstrate that many elements of material culture that characterise the lifestyle of San hunter-gatherers in southern Africa, were part of the culture and technology of the inhabitants of this site 44,000 years ago," says Backwell.
A key question in human evolution is when in prehistory human cultures similar to ours emerged? Until now, most archaeologists believed that the oldest traces of San hunter-gatherer culture in southern Africa dates back 10,000, or at most 20,000 years.
The international team of researchers, led by Francesco d'Errico, Director of Research at the French National Research Centre, dated and directly analysed objects from archaeological layers at Border Cave.
Located in the foothills of the Lebombo Mountains in KwaZulu-Natal, South Africa, the site has yielded exceptionally well-preserved organic material.
Backwell says their results have shown without a doubt that at around 44,000 years ago the people at Border Cave were using digging sticks weighted with perforated stones, like those traditionally used by the San.
"They adorned themselves with ostrich egg and marine shell beads, and notched bones for notational purposes. They fashioned fine bone points for use as awls and poisoned arrowheads. One point is decorated with a spiral groove filled with red ochre, which closely parallels similar marks that San make to identify their arrowheads when hunting," says Backwell.
