Oxford researchers were among a team of archaeologists who discovered shell beads
believed to be 82,000 years old – making them the oldest dated human
decorations. These finds of handmade beads, in a limestone cave in Morocco,
suggest that humans were fashioning purely symbolic objects in Africa 40,000
years before they did it in Europe. A paper on the discovery is published in
this month’s Proceedings of the National Academy of Sciences.
The discovery of beads at the Grotte des
Pigeons, Taforalt, in Eastern Morocco was made by an international team of
archaeologists from the UK, Morocco,France and Germany.Twelve Nassarius shells were
perforated in their centres, and showed signs of being suspended.They
also appeared to have been covered in red ochre, like other less well-dated
African beads. These symbolic, decorative objects are considered early signs of
modern human behaviour and mark shifts in human development. Similar beads have
been found at sites from Algeria, Israel, and South Africa, which probably date
back to about the same time or slightly after the finds from Taforalt.
Lead author Professor Nick Barton, Director of
Oxford’s Institute of Archaeology, said: ‘ Bead making in Africa was a
widespread practice at the time, which was spread between cultures with
different stone technology by exchange, or by long-distance social
networks.
‘A major question in evolutionary studies
today is “how early did humans begin to think and behave in ways we would see
as fundamentally modern?”. The appearance of ornaments such as these may be
linked to a growing sense of self-awareness and identity among humans, and
cultural innovations must have played a large role in human development.’
Preliminary work by the team has also shown that
these Nassarius shells are not isolated occurrences, but are present
at various other sites in Morocco. The researchers are waiting for the dating
results for these, but they may turn out to be even older than the discovery at
Taforalt.
Professor Nick Barton from Oxford University and Dr Abdeljalil Bouzouggar, from the Institut National des Sciences de l'Archéologie et du Patrimoine, Rabat, Morocco, were lead authors of the paper ‘82,000-year-old shell beads from North Africa and implications for the origins of modern Africa’. The research project was supported by the Moroccan Ministry of Culture.
