The Dani radical of New Guinea behaviour akin rituals today. (Hirofumi Matsumura and Hsiao-chun Hung)
Mummifying the dormant is simply a funerary rite that has been practiced for thousands of years successful galore locations crossed the world.
A caller find reveals that we whitethorn person been underestimating precisely however wide the signifier has been. Bones that amusement signs of deliberate mummification person been recovered crossed Southeast Asia and confederate China, with ages dating backmost to the pre-Neolithic play up to 12,000 years ago.
That's respective thousands of years older than the cultures champion known for mummification, the Chinchorro radical of Chile, who were mummifying their dormant 7,000 years ago, and the past Egyptians, who were practicing the trade 5,600 years ago.

A middle-aged pistillate from confederate China who was smoke-mummified anterior to burial. (Zhen Li)The crushed we mightiness person missed it? The method utilized by the earlier Asian cultures is rather antithetic from the much well-known mummification practices. According to a squad led by archaeologist Hsiao-chun Hung of the Australian National University, the individuals successful their survey were dilatory smoked implicit an unfastened occurrence for agelong stretches of time.
This signifier is akin to burials seen successful Australia and New Guinea astatine a somewhat aboriginal date, suggesting a taste nexus via shared funerary rites.
"Our burial samples from Southeastern Asia item a remarkably enduring acceptable of taste beliefs and mortuary practices that persisted for implicit 10,000 years among hunter-gatherer communities who were related done their craniofacial attributes and genomic affinities to Indigenous New Guinea Highland and Australian populations," the researchers constitute successful their paper.
Early and Middle Holocene quality burials from confederate China. (Hung et al., PNAS, 2025)Archaeologists had antecedently noticed that a ample fig of pre-Neolithic burials crossed a wide geographical portion that includes Southeast Asia and confederate China person a batch successful common. In many, the idiosyncratic is curled successful a crouching oregon fetal position, tightly bound successful place. Moreover, galore of these burials amusement immoderate burning of the bones.
How these cultures processed their dormant for burial, and however they achieved the distinctive burial postures, person been unfastened questions. Hung and her colleagues postulated that the remains were smoke-dried, successful a akin mode to however immoderate New Guinea Highlands cultures process their dormant to this day.
The probe team's introspection progressive 69 bony samples from 54 pre-Neolithic burials, dating betwixt 4,000 and 12,000 years ago, from 11 antithetic sites crossed confederate China, bluish Vietnam, and Indonesia.
A smoke-mummified antheral who died successful mediate age, immoderate 9,000 years ago. (Yousuke Kaifu and Hirofumi Matsumura)These bones were subjected to X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). XRD is peculiarly effectual astatine detecting changes to the operation of the bony that hap nether temperatures higher than 500 degrees Celsius (932 Fahrenheit). FTIR is amended for detecting bony changes induced by vulnerability to little temperatures.
Five of the samples did not instrumentality reliable FTIR results, which near 64 samples. Most of these – astir 84 percent – showed grounds of vigor exposure. Some of the bones besides had soot deposits, portion antithetic bones taken from the aforesaid idiosyncratic returned antithetic values, suggesting that the heating was applied selectively. There were besides chopped marks connected immoderate of the bones.
Based connected their findings, the researchers judge that the process was akin to the modern-day rites of the Dani people successful New Guinea. The deceased idiosyncratic is tightly bound earlier being suspended implicit low, smoky fires for periods of weeks to months. Cuts connected the bones could bespeak cuts made for drainage oregon disarticulation purposes.
Smoke-mummified individuals from New Guinea, photographed successful January 2019. Both are kept successful backstage households. (Hung et al., PNAS, 2025)Once the idiosyncratic is sufficiently mummified, the burial rites tin continue. For the Dani people, that involves open-air displays; for pre-Neolithic cultures, it appears to person been burial.
These findings suggest that deliberate mummification is acold much wide astir the world, much analyzable and varied, and older than we thought.
"The contented of smoked mummification serves arsenic compelling grounds of semipermanent taste persistence betwixt past Southeastern Asian and ethnographic Papuan and Australian mortuary practices. Furthermore, archaeological findings suggest that this contented whitethorn person been known among hunter-gatherer societies crossed a immense region, for galore millennia, extending from northeastern Asia and Jomon Japan to occidental Oceania and Australia, and perchance farther," the researchers write.
"Through this practice, the smoked and preserved remains of the deceased allowed radical to prolong carnal and spiritual connections with their ancestors, bridging clip and memory."
The probe has been published successful The Proceedings of the National Academy of Sciences.
