A 2.6-million-year-old Paranthropus fossil has been discovered in Ethiopia, which may indicate that these early hominins had a wider range than previously thought. The fossil, a jawbone, is significant for understanding human history and the development of early hominins. However, the discovery of 2.9-million-year-old stone tools at a nearby butchery site has raised questions about who actually made the first stone tools, with some outlets suggesting it may not have been the ancestors of modern humans.
