Recent research indicates that early humans utilized animal bones for tool-making over a million years earlier than previously believed, originating from the Acheulean period. Conducted by the Spanish National Research Council and Indiana University in East Africa, findings revealed 27 bone tools made mainly from elephants, hippos, and bovids. These discoveries, unearthed at Tanzania's Olduvai Gorge since 2015, push back the timeline for bone tool usage by human ancestors, indicating a shift in perception toward animals from competitors to resources. This challenges prior assumptions regarding the cognitive abilities of our ancestors.
"Now, we have a human species here that is able to innovate, to create an innovation by applying a knowledge they know they have or the working of stone."
"Earlier in time, things that preceded Homo sapiens were making large cutting tools out of bone and some other tools as well. But this shows that it's going much farther back in time."
