In a stunning revelation, scientists have unearthed a trove of stone tools on the Indonesian island of Sulawesi, hinting at the existence of early humans a staggering 1.5 million years ago. This groundbreaking find may challenge our understanding of human migrations between Asia and Australia.

A collaborative team of archaeologists from Australia and Indonesia discovered these ancient, chipped tools, which were likely used for cutting small animals and shaping rocks. Located beneath the soil in the Soppeng region of South Sulawesi, these artefacts are now dated using radioactive tracing methods.

Published in the journal *Nature* this past August, these findings are poised to reshape long-held beliefs about early human habitation in the Wallacea region. Previously, experts believed that Homo Erectus, the earliest known inhabitants, had settled only in Flores and the Philippines around one million years ago, with many thinking they lacked the seafaring skills necessary for vast ocean crossings.

Adam Brumm, the lead archaeologist from Griffith University in Queensland, emphasized the significance of these discoveries, stating, "These were artefacts made by ancient humans who lived long before Homo Sapiens appeared. We believe Homo Erectus successfully traversed the ocean from the Asian mainland to reach Sulawesi at least a million years ago."

The Wallacea region, an exotic tapestry of islands such as Sulawesi, Lombok, Flores, Timor, and Sumbawa, lies nestled between Borneo, Java, Australia, and New Guinea. Named after the pioneering naturalist Alfred Russel Wallace, this region offers a rich habitat for diverse flora and fauna and now, potentially, a deeper understanding of human ancestry.

This discovery not only adds to the intrigue of early human history but also opens new chapters in understanding how our ancestors adapted to and traveled across challenging landscapes. Stay tuned as more revelations about our ancient relatives emerge!
