| Abstract: | Postcranial skeletal studies have demonstrated thatPan paniscus is a more gracile animal thanPan troglodytes, with different arm to leg proportions. Published data on external body dimensions are extremely rare forPan paniscus, however. We present here a series of such measures for a sample ofpaniscus, and we compare these to similar measures forPan troglodytes. This comparison further clarifies the morphological distinctions between the two chimpanzee species, and indicates that
bonobos have longer legs and smaller chest girths relative to overall body height than doPan troglodytes chimpanzees. |
