Dawn of artificial mummification pushed back 5,000 years

Archaeologists working in southeast Asia have lengthy been puzzled by pre-farming burials courting from about 12,000 to 4,000 years in the past. Unlike later Neolithic graves, the place folks had been usually laid flat, these older burials usually present our bodies tightly crouched or squatting, typically with patches of darkened bone. Such contorted postures are arduous to attain if a physique is buried quickly after demise.

Now, a research in Proceedings of the National Academy of Sciences by scientists from throughout Asia has reported that many of these communities gently heated and smoked their lifeless to protect them, very similar to practices recorded in current occasions within the New Guinea Highlands. The findings clarify the postures in addition to pushes back the earliest proof for artificial mummification by 5 millennia.

The group documented dozens of pre-Neolithic burials from 11 websites. Then they studied the bones utilizing X-ray diffraction and Fourier-transform infrared spectroscopy. The group additionally in contrast outcomes from completely different bones of the identical individual and used radiocarbon courting.

About 84% of the examined bones confirmed elevated crystallinity and almost a 3rd reached values typical of stronger heating. Diffraction recognized a number of samples heated to round 525º C or extra. Burn traces clustered on the brow, knees, and elbows whereas different components confirmed solely delicate or no modifications. Crucially, completely different bones from the identical particular person usually recorded completely different warmth ranges, which was proof towards results because of the soil. Together with the intense crouching, which left no empty house for comfortable tissue, the outcomes match a situation through which our bodies had been tightly sure and suspended over smoky, low fires for lengthy intervals, then saved for a time and eventually buried.

The follow appeared at the least 14,000 years in the past, sooner than the Chinchorro (~7,000 years in the past).

“Pushing back the earliest known case of artificial mummification by about 5,000 years shows that these early communities already had remarkable spiritual beliefs and technical skills,” Australian National University senior analysis fellow and the research’s first writer Hsiao-chun Hung instructed The Hindu.

“It highlights their deep concern for the dead and their willingness to devote great effort to preserving the body as part of community life. This discovery changes how we understand early human culture: it shows that long before we thought, people had developed symbolic thinking, strong social bonds, and rituals that kept the living closely connected with their ancestors.”
