研究发现早期人类祖先的手是多才多艺的,既用于攀登,也用于工具制造。 Study finds early human ancestors' hands were versatile, used for both climbing and tool-making.

一项新的研究表明,早期的人类祖先,包括Australopithecus sediba和Naledi同性恋,用他们的手来攀登和制造工具。 A new study shows that early human ancestors, including Australopithecus sediba and Homo naledi, used their hands for both climbing and making tools. 科学家利用3D扫描分析化石手的骨头厚度,揭示了各种活动造成的压力模式。 Scientists used 3D scanning to analyze bone thickness in fossilized hands, revealing stress patterns from various activities. 这表明早期人类的手势是多才多艺的, 挑战了简单的进化进化 从“类人”到“类人”的手功能的想法。 This suggests early humans were versatile in their hand use, challenging the idea of a simple evolutionary progression from "ape-like" to "human-like" hand functions.
