Two slightly burnt, fat-covered sticks discovered inside an Australian cave are evidence of a healing ritual that was passed down unchanged by more than 500 generations of Indigenous people over the last 12,000 years, according to new research.

The wooden sticks, found poking out of tiny fireplaces, showed that the ritual documented in the 1880s had been shared via oral traditions since the end of the last ice age, a study in the journal Nature Human Behaviour said on Monday.

The discovery was made inside Cloggs Cave in the foothills of the Victorian Alps in Australia's southeast, in a region long inhabited by the Gunaikurnai people.

When the cave was first excavated in the 1970s, archaeologists discovered the remains of a long extinct giant kangaroo that had previously lived there.

But the Gunaikurnai people were not involved in those digs, "nor were they asked for permission to do research there", lead study author Bruno David of Monash University told AFP.

Further excavations starting from 2020 included members of the local Gunaikurnai Land and Waters Aboriginal Corporation (GLaWAC).

Carefully digging through the soil, the team found a small stick poking out—then they found another one. Both well-preserved sticks were made from the wood of casuarina trees.

Each one was found in a separate fireplace around the size of the palm of a hand—far too small to have been used for heat or cooking meat.

The slightly charred ends of the sticks had been cut specially to stick into the fire, and both were coated in human or animal fat.

One stick was 11,000 years old and the other 12,000 years old, radiocarbon dating found.

"They've been waiting here all this time for us to learn from them," said Gunaikurnai elder Russell Mullett, a co-author of the study and head of GLaWAC.

Mullett spent years trying to find out what they could have been used for, before discovering the accounts of Alfred Howitt, a 19th-century Australian anthropologist who studied Aboriginal culture.

Some of Howitt's notes had never been published, and Mullett said he spent a long time convincing a local museum to share them.

In the notes, Howitt describes in the late 1880s the rituals of Gunaikurnai medicine men and women called "mulla-mullung".

One ritual involved tying something that belonged to a sick person to the end of a throwing stick smeared in human or kangaroo fat. The stick was thrust into the ground before a small fire was lit underneath.

"The mulla-mullung would then chant the name of the sick person, and once the stick fell, the charm was complete," a Monash University statement said.

The sticks used in the ritual were made of casuarina wood, Howitt noted.

Jean-Jacques Delannoy, a French geomorphologist and study co-author, told AFP that "there is no other known gesture whose symbolism has been preserved for such a long time".

"Australia kept the memory of its first peoples alive thanks to a powerful oral tradition that enabled it to be passed on," Delannoy said.

"However in our societies, memory has changed since we switched to the written word, and we have lost this sense."

He lamented that the ancient animal paintings found in French caves would probably "never reveal their meaning" in a similar way.

Indigenous Australians are one of the oldest continuous living cultures, and Mullett said the discovery was a "unique opportunity to be able to read the memoirs of our ancestors".

It was "a reminder that we are a living culture still connected to our ancient past," he added.
