本研究描述了圈养非洲象和亚洲象，Loxodonta africanaandElephus maximus，分别和野生非洲象的工具使用潜力，并探讨了这种行为的生态和进化意义。比较的类型，多样性和频率的工具使用的圈养和野生大象与其他已知的工具使用的哺乳动物提供的工具使用行为的进化意义进行评估的手段。关于工具使用的起源和进化意义的几个假设进行了研究，并提出，在大象，工具的使用可能作为适应，使这些无毛，大型热带陆地哺乳动物，以科普体外寄生虫和体温调节。
This study describes the tool-use potentials of captive African and Asian elephants,Loxodonta africanaandElephus maximus, respectively, and wild African elephants and explores the ecological and evolutionary significance of this behaviour. Comparison of the types, diversity and frequency of tool use by captive and wild elephants with other known tool-using mammals is offered as a means for evaluating the evolutionary significance of tool-using behaviour. Several hypotheses concerning the origin and evolutionary significance of tool use are examined, and it is proposed that in elephants, tool use may serve as adaptations enabling these furless, large-bodied tropical land mammals to cope with ectoparasites and thermoregulation.
