在坦桑尼亚发现的古老的骨骼工具 将先进手工艺的时代推后一百万年 Ancient bone tools found in Tanzania push back date of advanced craftsmanship by a million years.

研究人员在坦桑尼亚的奥杜瓦伊峡谷发现27个可追溯到150万年前的骨骼工具,将古老骨骼工具的使用时间推后约100万年。 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. 这些工具可能是用大象和河马骨制成的, 用来屠宰动物, 这表明早期人类拥有比先前想象的 更复杂的工具箱。 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. 这一发现表明，像 Homo erectus、Homo habilis 或 Paranthropus boisei 这样的物种能够使用先进的工艺，使用骨骼的方式类似于他们使用石头的方式。 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.
