考古学家发现了迄今为止最早的木工技术证据。根据发表在《人类进化杂志》四月刊上的一份报告,属于直立人的150万年前的石器工具带有明显的金合欢木痕迹。这项新发现比已知最古老的木制工具早大约一百万年。

马德里康普顿斯大学的曼努埃尔·多明格斯-罗德里戈()及其同事在坦桑尼亚一个名为佩宁吉的遗址中挖掘出了古老的手斧,这些手斧是按照所谓的阿舍利文化传统制造的。随后对附着在工具上的基质进行的微观分析显示,木材残留物与已知的金合欢木残留物无法区分。此外,这些工具表现出磨损痕迹,表明它们曾被用于重型活动,例如硬木加工。

“这项研究的重要性在于,它表明人类在其进化的早期阶段,就已经生产了未能在考古记录中保存下来的木制工具,”研究人员在报告中写道。尽管有人认为,如此早期的人科动物缺乏必要的狩猎技术,但这项新研究开启了他们可能正在制造木制长矛的可能性。“这可能增强了他们作为猎人在开放环境中生存的能力,”该团队指出,“并让我们进一步了解当时人科动物的复杂智力。”
