A easy hand stencil discovered on a cave wall in Indonesia has been recognized because the oldest recognized instance of rock artwork on Earth. It surpasses a earlier discovery in the identical area by not less than 15,000 years.
A world analysis crew led by Griffith College, Indonesia’s nationwide analysis and innovation company (BRIN), and Southern Cross College decided that these work on the island of Sulawesi had been created not less than 67,800 years in the past.
Researchers say this breakthrough helps make clear when and the way people first reached Australia. The individuals who made the Sulawesi artwork had been possible intently associated to the ancestors of Indigenous Australians.
Historical Handprint and Superior Relationship Methods
The paintings was preserved in limestone caves in southeastern Sulawesi, on the close by island of Muna. Scientists recognized a partial hand stencil surrounded by a lot youthful work.
To find out its age, the crew used uranium-series relationship, inspecting tiny mineral layers that had fashioned over and generally beneath the paintings in Liang Metanduno cave. This allowed them to ascertain when the work had been created.
The hand stencil dates again not less than 67,800 years, making it the oldest reliably dated cave artwork ever discovered. It’s considerably older than one other Sulawesi portray recognized by the identical crew in 2024.
The findings additionally present that individuals continued creating artwork on this cave for a remarkably very long time. Inventive exercise spanned not less than 35,000 years, lasting till round 20,000 years in the past.
“It’s now evident from our new part of analysis that Sulawesi was residence to one of many world’s richest and most longstanding creative cultures, one with origins within the earliest historical past of human occupation of the island not less than 67,800 years in the past,” mentioned Professor Maxime Aubert, an archaeologist and geochemist from the Griffith Centre for Social and Cultural Analysis (GCSCR), who co-led the examine.
A Distinctive Claw-Like Handprint
The crew famous that this hand stencil stands out as a novel variation of a standard motif.
After it was first created, the picture seems to have been deliberately modified. The outlines of the fingers had been narrowed, giving the hand a claw-like look.
Professor Adam Brumm of Griffith College’s Australian Analysis Centre for Human Evolution (ARCHE), a co-leader of the examine, mentioned the that means behind this alteration stays unsure.
“This artwork might symbolize the concept people and animals had been intently linked, one thing we already appear to see within the very early painted artwork of Sulawesi, with not less than one occasion of a scene portraying figures that we interpret as representations of part-human, part-animal beings,” Professor Brumm mentioned.
Clues to Early Human Migration to Australia
Dr. Adhi Agus Oktaviana, a rock artwork specialist at BRIN and a crew chief whose doctoral analysis at Griffith College contributed to the examine, mentioned the invention has main implications for understanding the deep historical past of Australian Aboriginal tradition.
“It is rather possible that the individuals who made these work in Sulawesi had been a part of the broader inhabitants that will later unfold by the area and finally attain Australia,” Dr. Oktaviana mentioned.
For years, archaeologists have debated when people first arrived on the traditional landmass generally known as Sahul, which as soon as linked present-day Australia, Tasmania and New Guinea.
Some researchers help a brief chronology, suggesting people arrived round 50,000 years in the past. Others favor an extended chronology, inserting their arrival not less than 65,000 years in the past.
“This discovery strongly helps the concept the ancestors of the First Australians had been in Sahul by 65,000 years in the past,” Dr. Oktaviana mentioned.
Migration Routes and Ongoing Analysis
Scientists have proposed two predominant pathways into Sahul. One is a northern route by Sulawesi and the ‘Spice Islands’ towards New Guinea. The opposite is a southern route that carried early seafarers extra on to Australia through Timor or close by islands.
Professor Renaud Joannes-Boyau of the Geoarchaeology and Archaeometry Analysis Group (GARG) at Southern Cross College mentioned the brand new proof strengthens the case for the northern route.
“With the relationship of this extraordinarily historic rock artwork in Sulawesi, we now have the oldest direct proof for the presence of recent people alongside this northern migration hall into Sahul,” Professor Joannes-Boyau mentioned.
“These discoveries underscore the archaeological significance of the numerous different Indonesian islands between Sulawesi and westernmost New Guinea,” mentioned Professor Aubert, who continues working with colleagues to uncover extra proof of early human exercise alongside this route with help from the Australian Analysis Council (ARC).
The ARC funding is a part of a broader effort to review human origins. This consists of the ARC Centre of Excellence for Remodeling Human Origins Analysis, led by Griffith College, and the ARC Coaching Centre for Advancing Archaeology within the Assets Sector at Southern Cross College. These initiatives goal to develop data of human evolution and assist defend cultural heritage.

The Sulawesi discoveries have additionally been featured in a documentary, ‘Sulawesi l’île des premières photographs,’ produced by ARTE and launched in Europe.
The examine, titled ‘Rock artwork from not less than 67,800 years in the past in Sulawesi,’ was printed in Nature.
