Ancient humans crafted bone tools 1.5 million years ago

Recent discoveries at Tanzania's Olduvai Gorge have revealed that early human ancestors were crafting tools from animal bones as far back as 1.5 million years ago, significantly earlier than previously believed. This collection of 27 carved bones, primarily from elephants and hippos, indicates a systematic approach to tool-making that involved techniques similar to those used for stone tools, suggesting advanced cognitive skills and cultural transmission among early hominins. Researchers assert that these bone tools, likely used for butchering, reflect a broader understanding of raw materials and technology, marking a pivotal moment in human evolution. The findings challenge the long-held view that bone tools were used opportunistically rather than through deliberate crafting. The study emphasizes the importance of these tools in expanding the toolkit of early humans, showcasing their ability to adapt techniques across different materials. The implications of this research may lead to further discoveries regarding early human technological development and behavior.
