The intermembral index for a chimpanzee is 106 to the 12th degree whereas the intermembral index for a human is 88 to the 11th degree. The intermembral index is a ratio of limb proportions that provides insight into the type of locomotion of an animal.
Quantitative differences between adult humans, chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) are given in Table 13.1. The combined values for the intermembral index and the humerofemoral index show
A high intermembral index in chimpanzees reflects the fact that they rely heavily on their forelimbs for climbing and arm-hanging/swinging activities. Lucy's intermembral index is 88 11. Thus, Lucy appears to have an intermediate measurement between modern humans and chimpanzees.
The intermembral index is a ratio used to compare limb proportions, expressed as a percentage. It is equal to the length of forelimbs (humerus plus radius) divided by the length of the hind limbs (femur plus tibia) multiplied by 100, otherwise written mathematically as: (+) (+) ×The intermembral index is used frequently in primatology, since it helps predict primate locomotor patterns.

Other articles where Intermembral index is discussed: primate: Four types of locomotion: …being strictly quantitative, is the intermembral index. Briefly, the index is a ratio expressed as percentage of arm length to leg length; an index over 100 indicates relatively long arms. This provides a model by means of which the locomotion of an early primate can be inferred by determination of…
They have an intermembral index of 145 and are slow, arboreal climbers. Large adult males spend more time on the ground, because they are too heavy to travel efficiently between the tree branches. Size and weight: Sexual dimorphism is pronounced. Males are approximately 970mm tall and weigh 87kg, whereas females are only 780mm tall and weigh ...
