人口水平的右撇子在历史上被认为是人类进化的标志。尽管最近对黑猩猩（Pan troglodytes）的研究已经证明了某些行为的群体水平的右利手，但一些人质疑这些发现的有效性和一致性，认为报告的侧化效应是特定于某些猿群和人类饲养的黑猩猩。作者报告了在3个独立的黑猩猩群体中存在右利手的证据。此外，在3个殖民地的利手是无关的比例，由人类提出的主题。这是迄今为止最有力的证据，表明黑猩猩的群体水平的惯用手是明显的，而不是人类饲养的人工制品。
Population-level right-handedness has historically been considered a hallmark of human evolution. Even though recent studies in chimpanzees (Pan troglodytes) have demonstrated population-level right-handedness for certain behaviors, some have questioned the validity and consistency of these findings by arguing that reported laterality effects are specific to certain colonies of apes and to those chimpanzees reared by humans. The authors report evidence of population-level right-handedness in 3 separate colonies of chimpanzees. Moreover, handedness in the 3 colonies was unrelated to the proportion of subjects that were raised by humans. This is the strongest evidence to date that population-level handedness is evident in chimpanzees and is not an artifact of human rearing.
