Human tool behavior is species-specific. It remains a diagnostic feature of humans, even when comparisons are made with closely related non-human primates. The archaeological record demonstrates both the deep antiquity of human tool behavior and its fundamental role in distinguishing human behavior from that of non-human primates.
人类的工具行为具有物种特异性。即使与亲缘关系较近的非人类灵长类动物进行比较，它仍然是人类的一个诊断特征。考古记录既证明了人类工具行为的悠久历史，也证明了它在区分人类行为与非人类灵长类动物行为方面的基本作用。
