Ancient 'Hobbit' Humans Enigma Deepens with Stone Tool Findings Unveil

Ancient Stone Tools Discovered in Indonesia Reshape Early Human Migration Theories

In a groundbreaking discovery, archaeologists have unearthed stone tools dated between 1 million and 1.5 million years old on the Indonesian island of Sulawesi. This find, published in the prestigious journal Nature, provides the earliest direct evidence that hominins—likely Homo erectus or another early human relative—occupied this island much earlier than previously thought.

The tools, found by a team led by Budianto Hakim from the National Research and Innovation Agency, were discovered at a site in Calio, near an ancient river channel during the Early Pleistocene. The seven stone tools, including the oldest one found two feet deeper underground, are simple but deliberate flakes made by percussion flaking, with sharp edges suitable for cutting or scraping.

The discovery challenges existing theories about early human dispersal routes and capabilities. Until now, the earliest evidence for hominins in Wallacea, the transitional biogeographical zone between Asia and Australia, was around 1 million years ago on Flores and Luzon islands. The Sulawesi tools push back human presence in this island region, implying early hominins, possibly Homo erectus, reached these islands by crossing significant oceanic barriers, which was thought unlikely due to limited watercraft technology at the time.

Adam Brumm, a co-author of the study and a Professor of archaeology at Griffith University in Australia, stated that the discovery indicates that early hominins had the behavioral and technological means for maritime travel or island hopping far earlier than previously documented in Southeast Asia.

The ancient inhabitants of Sulawesi are believed to have been an earlier species, possibly related to the "hobbit" humans (Homo floresiensis) discovered on Flores. The "hobbit" species, who lived around 60,000 to 100,000 years ago, were very small, approximately 3 feet tall. Another small-sized ancient species, Homo luzonensis, was found on the island of Luzon in the Philippines. However, no earlier species have been identified as the creators of these ancient tools on Sulawesi.

The discovery of these ancient tools suggests a potential link between the ancient Flores and Sulawesi populations. Until now, the earliest evidence of hominin activity on Sulawesi was about 194,000 years ago. This new find, led by Gerrit van den Bergh from the University of Wollongong in Australia, reshapes our understanding of early human activity and migration in Southeast Asia, demonstrating early hominin presence on oceanic islands and suggesting more complex behaviors like early sea crossing during the Early Pleistocene.
