Sept. 9, 2022 A 31,000-year-old skeleton discovered in a cave in Borneo could be the earliest proof a surgical amputation in humans.
The skeleton within 2020 in Liang Tebo, a limestone cave in Indonesian Borneo, was missing its left foot and section of its left leg, in accordance with a report published in the journal Nature.
The leg bone had a clean cut, unlike a bone that were crushed, leading researchers to summarize it had been removed through deliberate surgical amputation at the positioning of the distal tibia and fibula shafts, Nature reported.
There have been no signs of infection, ruling out an animal attack and showing the individual received community care following the treatment. The surgery happened once the person was a kid, and they continued to call home 6 to 9 more years being an amputee.
The finding has scientists rethinking the theory that medical knowledge advanced when people switched from foraging to farming societies by the end of the Ice Age. Individuals who lived in Borneo 31,000 years back were foragers.
Previously, the initial known proof amputation have been within France in the 7,000-year-old skeleton of a Stone Age farmer whose left forearm was amputated above the elbow, in accordance with a news release from Griffith University in Australia. (The university done the project with Indonesias Centre for Archaeology, Language and History.)
What the brand new finding in Borneo demonstrates is that humans already had the opportunity to successfully amputate diseased or damaged limbs a long time before we began farming and surviving in permanent settlements, Maxime Aubert, PhD, an archaeologist with Griffith University and co-leader of the project, said in the news headlines release.
The finding shows that at the very least some modern human foraging groups in tropical Asia had developed sophisticated medical knowledge and skills a long time before the Neolithic farming transition, Nature reported.
Researchers determined the skeleton was 31,000 yrs . old by comparing teeth and burial sediment using radioisotope dating. The region where in fact the skeleton was found has a number of the earliest recognised human rock art.
