Recent research has identified rock art in Sulawesi, Indonesia, as the oldest known example, dated at over 67,000 years. This discovery provides significant insights into early human migrations, particularly as it may relate to the movement of populations toward Australia. The findings, published in the journal Nature, suggest that this art, consisting of a human hand stencil, represents a crucial link to our ancestors who likely embarked on one of the first migrations to Sahul, the ancient landmass connecting Australia, New Guinea, and Tasmania.
The stencil, discovered in the Liang Metanduno cave, features a faint outline of a human hand, which has been described as claw-like. According to study author Maxime Aubert from the Griffith Centre for Social and Cultural Research, this art form is evidence of a rich artistic culture that has persisted on the island for tens of thousands of years. Aubert stated, “It is now evident from our new phase of research that Sulawesi was home to one of the world’s richest and most longstanding artistic cultures.”
Sulawesi is a critical site in the narrative of human history, serving not only as a canvas for artistic expression but also as a likely staging ground for early migrations of Homo sapiens. The recent study builds on earlier research that indicated the island might have played a substantial role in the movement of populations from Asia to Sahul. The findings underscore the significance of Sulawesi in understanding human evolution and migration patterns.
In this latest research, the team utilized various dating techniques, including uranium-series dating and mineral deposit analysis, to establish that the stencil was created approximately 67,800 years ago. This timeline predates previously known rock art in the region by about 16,600 years. The hands depicted in the art are believed to belong to artists who were likely ancestors of modern Aboriginal Australians.
Adhi Agus Oktaviana, a study author from the National Research and Innovation Agency in Indonesia, emphasized the broader implications of the discovery. “It is very likely that the people who made these paintings in Sulawesi were part of the broader population that would later spread through the region and ultimately reach Australia,” he stated. This assertion aligns with theories suggesting that the ancestors of the First Australians were in Sahul by around 65,000 years ago.
Prior research has proposed two main timelines for when modern humans arrived in Sahul: the “long chronology” around 65,000 years ago and the “short chronology” around 50,000 years ago. These studies have also suggested that migration occurred via two primary routes: a northern path through Sulawesi and a southern path through Timor, which led to New Guinea and Australia.
The Liang Metanduno cave also contains younger artworks, indicating a significant period of habitation lasting at least 35,000 years. “With the dating of this extremely ancient rock art in Sulawesi, we now have the oldest direct evidence for the presence of modern humans along this northern migration corridor into Sahul,” said Renaud Joannes-Boyau, a researcher from the Geoarchaeology and Archaeometry Research Group at Southern Cross University in Australia.
As the research team looks ahead, their focus will expand to include further investigation into the rock art and migration patterns across the Indonesian archipelago, particularly the islands between Sulawesi and New Guinea. Aubert noted the archaeological importance of these regions, suggesting that they could yield additional insights into the early movements of humans.
This groundbreaking study not only sheds light on the ancient artistic expressions of our ancestors but also reinforces the notion that the islands of Indonesia were crucial in shaping the migration narratives of early human populations. The implications of this research extend beyond art history, offering a deeper understanding of human evolution and settlement patterns in the Asia-Pacific region.
