两种类型的度量已被建议测量形态距离，一个基于数量性状和其他数量性状。量子特征是那些状态变化并被评分为0或1（舌头的存在或不存在）的特征。数量性状是指那些状态连续变化的性状（腿长），在这种情况下，状态之间的差异程度是定量测量的。Findley（1）建议使用量子性状来比较人类与黑猩猩之间以及青蛙之间形态差异的大小。他选择了六个量子特征，
Two types of metric have been suggested to measure morphological distance, one based on quantal traits and the other on quantitative traits. Quantal traits are those whose state varies and is scored as 0 or 1 (presence or absence of a tongue). Quantitative traits are those whose state varies continuously (length of leg), and in this case the degree of difference be-tween states ismeasured quantitatively. Findley (1) recommends that quantal traits be used for comparing the magnitude of the morphological difference be-tween humans and chimpanzees with that between frogs. He chooses six quan-tal traits such that the state in Xenopus
