Archaeologists have found a 31,000-year-old skeleton of a man in a cave in Indonesia missing his left leg, reportedly proving that amputation or bone removal surgeries were known to Stone Age people.
It is also the oldest evidence of amputation known so far.
A study published in Nature.com on Wednesday reveals "the discovery of skeletal remains of a young individual from Borneo who had the distal third of their left lower leg surgically amputated, probably as a child, at least 31,000 years ago."
"The individual survived the procedure and lived for another 6–9 years," the research reads.

The remains were found in the Liang Tebo cave, located in East Kalimantan, Indonesian Borneo, which also has some of the world's oldest-dated rock art.
"Evidence of a successful limb amputation suggests that at least some modern human foraging groups in tropical Asia had developed sophisticated medical knowledge and skills long before the Neolithic farming transition (10,000 years ago)," the study reads.
"The remaining leg bone showed a clean, slanted cut that healed over," said Tim Maloney, an archaeologist at Griffith University in Australia and the study's lead researcher, adding that child could have been bitten by a creature like a crocodile.
This early surgery "rewrites the history of human medical knowledge and developments," Maloney added.
