Turkish archaeologists have found the oldest-yet evidence of body piercing in human remains dating back 11,000 years.
The findings, published in the journal Antiquity, suggests that the practice had a social significance.
The body ornaments were found next to the ears and chins of excavated human remains, suggesting they were worn like modern-day piercings.
The team observed that only adults had piercings, indicating that they were part of a rite of passage into adulthood.
The team unearthed more than 106 ornaments buried in the graves of individuals dating back 11,000 years at the Boncuklu Tarla, a Neolithic settlement in the present-day Mardin province in southeast Turkiye.
The ornamental pieces were crafted from raw materials like river pebbles, limestone, chlorite, flint, obsidian and copper.
Eighty-five of the ornaments found were complete. According to the paper, the sizes and shapes of the jewellery suggest the pieces were suited for ear and mouth decorations.
The ornaments were not found in child burials at the excavation site.
"It shows that traditions that are still very much part of our lives today were already developed at the important transitional time when people first started to settle in permanent villages in western Asia more than 10,000 years ago," said Dr. Emma Baysal, co-author of the paper "They had very complex ornamentation practices involving beads, bracelets, and pendants, including a highly developed symbolic world which was all expressed through the medium of the human body."
