在坦尚尼亞，考古學家發現了一組距今約 150 萬年的骨器工具，這是人類演化史上的一大突破！這些工具可能是由直立人製作而成，選用大象和河馬堅硬的肢骨製作而成，是目前最早有系統地使用非石材材料製作工具的證據。這項發現顯示，早期人類不只懂得利用動物作為食物，還有意識地把它們當作資源加以應用。📚 本集文法學習重點：1️⃣ 所有格形容詞（Possessive adjectives）例句：[...] while also adapting their methods to the bones' unique properties, such as its collagen content and layered structure.2️⃣ 語篇標記（Discourse markers）例句：In other words, this shows an awareness of animals not only as food but also as a source of raw material.📖 本集故事簡介：A set of 27 bone tools found in Tanzania, dating back around 1.5 million years, marks a significant technological milestone in human evolution. Likely crafted by Homo erectus, these tools — made from the dense limb bones of elephants and hippos — represent the earliest known example of systematic tool-making using materials other than stone. While bone tools had previously been used sporadically, this discovery suggests a deliberate and skilled approach. The tools, some reaching 37.5 cm in length, were probably used for butchering animals. Their creation required anatomical knowledge, as only thick, durable bones were selected. Researchers believe these early humans applied knapping techniques similar to stone tool-making, while also adapting their methods to the bones' unique properties, such as its collagen content and layered structure. This innovation does reflect a growing cognitive capacity and resourcefulness. In other words, this shows an awareness of animals not only as food but also as a source of raw material.📲 Readle App 下載連結：⁠https://readle-app.onelink.me/cKqE/8suoeb2w
