Sibley和Ahlquist使用DNA-DNA杂交比较了类人猿灵长类的单拷贝核DNA序列。根据这些数据，他们用距离瓦格纳法估计了人类和黑猩猩的亲缘关系。然而，尽管他们的数据集包含关于正确分支顺序的内部不一致性，但没有对该估计的分支发生率进行统计学置信度评估。本文提出了一个修改的Pielou的Q-统计量，允许一个非参数测试的系统发育关系的距离数据。该分析的结果表明，由于数据集的内部不一致性，Sibley和Ahlquist的估计同源性没有统计学意义。对其他类型的分子数据的调查和额外分析表明，黑猩猩和大猩猩的集群和人类谱系较早分裂的遗传学与所有分子数据（包括DNA-DNA杂交数据）在统计学上一致，而Sibley和Ahlquist估计的遗传学可以在5%的水平上使用线粒体基因组中限制性内切酶位点的数据被拒绝。
Sibley and Ahlquist compared the single-copy nuclear DNA sequences of the hominoid primates using DNA-DNA hybridization. From this data set they estimated a phylogeny that clusters man and chimpanzees using a distance Wagner procedure. However, no assessment of statistical confidence in this estimated phylogeny was made, despite the fact that their data set contains internal inconsistencies concerning the correct branching order. This paper presents a modification of Pielou's Q-statistic that allows one to make nonparametric tests of phylogenetic relationship from distance data. The results of this analysis indicate that the estimated phylogeny of Sibley and Ahlquist is without statistical significance owing to the internal inconsistencies of the data set. A survey and additional analyses of other types of molecular data indicate that the phylogeny that clusters chimpanzees and gorillas and has the human lineage splitting off earlier is statistically consistent with all the molecular data (including the DNA-DNA hybridization data), whereas the phylogeny estimated by Sibley and Ahlquist can be rejected at the 5% level using the data on restriction-endonuclease sites in the mitochondrial genome.
