The world's earliest limb amputation — dating back 31,000 years — has been discovered in Borneo.
It gives a fascinating insight into the medical abilities of people in the Stone Age.
Studies on the skeleton buried in a cave found that, after the surgery, they went on to live for six to nine years.
Previously, the earliest recorded amputation was carried out 7,000 years ago on a Neolithic farmer from France.
They explained that intensive post-operative care of the patient, including temperature regulation, bathing, wound care, and disinfection, would have been vital for the patient.
