A 31,000-year-old skeleton missing its lower left leg and found in a remote Indonesian cave is believed to be the earliest known evidence of surgery, according to a peer-reviewed study that experts say rewrites understanding of human history.

An expedition team led by Australian and Indonesian archaeologists stumbled upon the skeletal remains while excavating a limestone cave in East Kalimantan, Borneo looking for ancient rock art in 2020.

The finding turned out to be evidence of the earliest known surgical amputation, pre-dating other discoveries of complex medical procedures across Eurasia by tens of thousands of years.
