物种水平的右利手习惯通常被认为是人类所独有的。惯用手被认为与我们的语言能力相关，并被用作追踪语言进化的一种手段。在这里，我们研究了手在3个圈养组倭黑猩猩（潘paniscus），包括22个人。我们没有发现物种水平的利手现象。从这些发现可以得出的结论是：（1）物种水平的利手进化后，泛和人的血统分歧;（2）不一致的偏好可能代表人类利手的前兆，（3）泛可能有语言能力，但这些不能用利手来衡量。版权所有（C）2008 S. Karger AG，巴塞尔。
Species level right-handedness is often considered to be unique to humans. Handedness is held to be interrelated to our language ability and has been used as a means of tracing the evolution of language. Here we examine handedness in 3 captive groups of bonobos (Pan paniscus) comprising 22 individuals. We found no evidence for species level handedness. Conclusions that can be drawn from these findings are: (1) species level handedness evolved after the divergence of the Pan and Homo lineages; (2) inconsistent preferences may represent precursors to human handedness, and (3) Pan may have language abilities but these cannot be measured using handedness.
