40,000-Year-Old Indonesian Symbols Discovered
Archaeologists have uncovered a "lost chapter of human history" in 40,000-year-old symbols found in Indonesia, sparking debates about early symbolic communication and rewriting timelines of human cognitive development. The discovery suggests sophisticated symbolic thinking emerged thousands of years earlier than previously documented in this region.
- The symbols are part of a larger collection of ancient rock art discovered in the limestone caves of Sulawesi, Indonesia. This art includes the world's oldest known hand stencil, dated to be at least 67,800 years old, found in the Liang Metanduno cave on Muna Island. - Research in the Maros-Pangkep region of South Sulawesi has also uncovered some of the earliest known figurative art. This includes a painting of a Sulawesi warty pig in Leang Tedongnge cave, which is at least 45,500 years old, and a narrative scene of human-like figures hunting animals in Leang Bulu' Sipong 4, dated to at least 50,200 years old. - The discoveries were made by a team of researchers including Maxime Aubert from Griffith University in Australia and Indonesian archaeologist Adhi Agus Oktaviana. Their work has been instrumental in overturning the long-held Eurocentric view that complex symbolic art first emerged in Europe. - To determine the age of the art, scientists used a technique called uranium-series dating on mineral deposits that formed over the paintings. This method analyzes the decay of uranium into thorium in the calcite layers, providing a minimum age for the artwork underneath. - The symbols and figurative paintings were created using red ochre pigment. The hand stencils were likely made by pressing a hand against the cave wall and spraying it with a mouthful of ochre mixed with water. - These findings suggest that the ancestors of the first people to arrive in Australia, who would have passed through this region, already possessed sophisticated artistic and symbolic traditions. The presence of this complex art provides crucial context for understanding the cognitive abilities required for the sea-faring journeys to the continent of Sahul (present-day Australia and New Guinea). - The art often depicts animals endemic to Sulawesi, such as the babirusa ('pig-deer') and the bear cuscus, indicating a deep connection between the early inhabitants and their new environment. This focus on local fauna suggests a process of "symbolic negotiation" with the unfamiliar species they encountered.
