For at least 10,000 years, humans across South-East Asia were being carefully preserved after death by being smoke-dried – a tradition that continues to this day in some cultures

Human bodies carefully preserved by smoking up to 14,000 years ago have been found at archaeological sites in South-East Asia, making them the oldest known mummies in the world.
A similar practice continues today among the Dani people in West Papua, Indonesia. The Dani mummify their deceased relatives by exposing the bodies to smoke, then keep and revere them as part of the household. Many of their mummies are tightly bound in crouching poses.

Similar “hyper-flexed” ancient human remains have also been found in Australia, China, the Philippines, Laos, Thailand, Malaysia, South Korea and Japan.
Hsiao-chun Hung, at the Australian National University in Canberra, says that while she was working on ancient skeletons in Vietnam in 2017, she was struck by the similarity of the burial remains they were excavating to the Dani’s tradition.
Hung and her colleagues studied 54 hunter-gatherer burials from 11 archaeological sites located across South-East Asia, dating from 12,000 to 4000 years ago, to look for evidence of the skeletons having been slowly smoked. Most of the sites were in northern Vietnam and southern China.
