Ancient bone tools found in Tanzania push back date of advanced craftsmanship by a million years.
Researchers have found 27 bone tools dating back 1.5 million years in Tanzania's Olduvai Gorge, pushing back the timeline for ancient bone tool use by about a million years.
Made from elephant and hippo bones, these tools were likely used for butchering animals, indicating that early humans had more complex tool kits than previously thought.
The discovery suggests that species like Homo erectus, Homo habilis, or Paranthropus boisei were capable of advanced craftsmanship, using bones similarly to how they used stones.
