A new estimate of the phylogenetic relationships among the nine gibbon taxa is presented, based on a compatibility analysis of 55 morphological and behavioural characters. The phylogeny presented here differs somewhat from those of other studies, but there appears to be a basic consensus that: the siamang and concolor gibbons represent the earliest forms to speciate; the agile, lar, moloch, Müller's, and pileated gibbons represent the lates forms to speciate; with the Kloss and hoolock gibbons representing intermediate forms. Although the hypotheses regarding the evolutionary direction of these characters remain subjective due to the lack of gibbons in the fossil record, the method used is totally objective in its approach and is repeatable when further data become available.
基于对55个形态和行为特征的兼容性分析，提出了对九种长臂猿分类群之间系统发育关系的新估计。这里呈现的系统发育与其他研究的有所不同，但似乎有一个基本共识：合趾猿和白颊长臂猿代表最早分化的形式；白手长臂猿、白眉长臂猿、银白长臂猿、穆氏长臂猿和戴帽长臂猿代表最晚分化的形式；克氏长臂猿和白掌长臂猿代表中间形式。尽管由于化石记录中缺乏长臂猿，关于这些特征进化方向的假设仍然主观，但所使用的方法在其方法上是完全客观的，并且当有更多数据可用时是可重复的。
