Discovered: An outline of a hand that’s at least 67,800 years old

The faded hand stencil, along with other spectacular cave paintings on the island of Sulawesi, were likely made by early humans who were part of a population that spread into a lost continent known as Sahul, which today encompasses Australia, Papua New Guinea and parts of Indonesia. "They're made with ochre. They put their hand there, and then they sprayed pigment. We can't tell which technique they used. They could have put pigment in their mouth and sprayed it. They could have used some sort of instrument," said Maxime Aubert, an archaeologist and geochemist from Griffith University in Australia. Aubert, who was the senior author of a study on the findings that published on Wednesday in the journal Nature, described the discovery as "thrilling and humbling." The minimum age of the hand stencil, which was modified at some point to create distinctive narrowed fingers, is older than dozens of other examples of prehistoric art found preserved in the region's intriguing limestone caves. Another example is a scene involving part human and part animal figures hunting a warty pig, the oldest evidence of storytelling in art history. "What we are seeing in Indonesia is probably not a series of isolated surprises, but the gradual revealing of a much deeper and older cultural tradition that has simply been invisible to us until recently," said Aubert.

The team found the oldest hand stencil in Metanduno cave on Muna island. The cave also features much fresher images of horses, deer and pigs that were painted perhaps 3500 to 4000 years ago, the study said. These paintings have long been a draw for tourists. Dating cave art is tricky and the team used a technique that analysed chemical traces in mineral crusts that form on top of the paintings, sometimes called cave popcorn, to provide a minimum age for the art. The rock art in Sulawesi is also older than Europe's famed cave art, such as Lascaux in France, and a hand stencil suspected to have been made by Neanderthals in a Spanish cave. Prehistoric Picassos The prehistoric people who made the hand stencils were most likely early members of our own species, Homo sapiens, who lived in Southeast Asia during the ice age. At that time, sea levels were much lower, and the region looked very different, the study noted. Aubert said that after the humans made the hand stencils, they narrowed the fingers, making them look like claws. He regarded the negative imprints of hands as examples of art that reveal complex behaviour- even though the stencils aren't figurative or narrative like the captivating scene of a warty pig hunt. For example, he said the hands were marking places that mattered to the artists. "This was not a casual activity. It required planning, shared knowledge and cultural meaning." The hand stencils were materially different from a 73,000 year-old stone flake uncovered in a South African cave that featured lines, which some had called the oldest known drawing. Aubert noted the lines were abstract and might not have been an intentional image. Paul Pettitt, a professor of palaeolithic archaeology who studies prehistoric art at the University of Durham in the United Kingdom, said that the date given to the hand stencil was a minimum age. It could be much older, he said, and it shouldn't be assumed that the hand stencil was made by Homo sapiens. Other human species, such as the poorly understood Denisovans, likely lived in the region, explained Pettitt, who wasn't involved in the study. "It's certainly unclear whether the narrow/pointy fingered hand stencils were deliberately modified or simply the result of moving the finger, but to call this complex is rather overinterpreting the hand stencil," he said via email. "Before writing grand narratives about the complexity and success of Homo sapiens we really should consider other, potentially more interesting explanations of this fascinating phenomenon." A perilous journey The presence of extremely old cave art in Sulawesi is also helping archaeologists answer hotly debated questions about how and when early humans reached a lost land known as Sahul. The land once connected Australia with the island of New Guinea, which today is divided into Papua New Guinea and Indonesian Papua. Some scholars think humans arrived in Sahul about 50,000 years ago, but others hypothesize they arrived at least 65,000 years ago. They also debate the route they likely took. The age of the Sulawesi cave art suggests that the ancestors of the first Australians were potentially in Sahul...
