Kluge 和 Kerfoot (1973) 根据几个脊椎动物数据集报道，不同地区性状的分化与相同性状的内部变异呈正相关。他们的分析方法受到批评，因为它会在没有地理分布的零情况下给出函数依赖性。提出了一种基于地区之间和地区内部变异系数的替代分析方法。当用这种方法重新检查 Kluge 和 Kerfoot 的数据集时，发现这种关系并不像这些作者报告的那么高或那么规律。对第一个无脊椎动物数据（来自蚜虫、苍蝇、蜗牛和原生动物）进行了分析，得出的结果与脊椎动物的研究结果相当。
Kluge and Kerfoot (1973) reported from several vertebrate data sets that interlocality character differentiation was positively correlated with intralocality variability for the same characters. Their method of analysis is criticized since it would give functional dependence in the null case of no geographic distribution. An alternative method of analysis is proposed based on coefficients of variation among and within localities. When Kluge and Kerfoot's data sets are reexamined by this method, the relationship is not as high or as regular as reported by these authors. The first invertebrate data (from aphids, flies, snails, and protozoa) are analyzed and yield results comparable to the findings on vertebrates.
